I am an artist who is always exploring different materials, tools, and processes.
Drying of Acrylic Paint
Water-based acrylic paint uses an acrylic emulsion to bind pigment. Notice I said an emulsion, not a solution. The acrylic resin does not dissolve in water, and therefore an emulsion is required to get a single phase liquid paint medium. When the water evaporates from acrylic paint, the polymer cross-links its molecules and forms an adherent acrylic-paint film. Once dry, the film is no longer water soluble. Therefore, to remove dried acrylic paint from a porous or nonporous surface, you will need a cleaner that is capable of dissolving acrylic resin or at least reducing its adhesion. However, please take note: Some solvents and cleaners may not be appropriate for some surfaces and materials. This article will go over the appropriate surfaces for each cleaning liquid.
Before we really get into the various household chemicals useful in removing paint from various surfaces, I feel it prudent to mention a few words on safety. Most of the liquids mentioned here pose some kind of hazard to health and property.
The most important danger to consider here is flammabilty. Four of the five liquids featured in this article are moderately to extremely flammable. Remember to not use alcohols and solvents anywhere near naked flames or energized heating elements. Do not use flammable liquids close to running electric motors unless they are specifically designed to be used in a fire hazard zone. Most electric motors emit sparks. The vapors of the most flammable, namely acetone and lacquer thinner, are heavier than air and can travel considerable distances to a source of ignition.
Most solvents are not only flammable but also nervous system depressants and may also be toxic. Be especially mindful of solvents that contain aromatic hydrocarbons such as toluene and xylene such as certain lacquer thinners. Aromatics increase toxicity and the need for better ventilation. Special care in making sure adequate ventilation is provided when working with organic solvents. Also, ammonia is an irritant and can cause asphyxiation in closed spaces. Not to mention ammonia is also corrosive. If possible, it is best to work outdoors.
The next consideration is health concerns. These liquids can be dangerous:
- To inhale or ingest: You should only use solvents in well-ventilated areas. Ingestion or excessive inhalation can be extremely hazardous. Both the denatured alcohol and lacquer thinner may contain methanol, which is highly toxic by ingestion. It can cause blindness and even death!
- To touch: Do not allow contact between the solvent and your skin as the liquids will penetrate and get absorbed into your body. Ammonia solution also produces noxious vapors and can irritate the skin. Wear gloves and protective eyewear to mitigate accidental exposure risk.
Now that we have assessed the risk, we shall proceed better prepared and more informed.
Five Liquids That Clean Dried Acrylic
|Cleaning Liquid||Appropriate Materials||Warnings|
Non-porous surfaces, such as metal, glass, and plastics
Gives off intense fumes, dissolves brass (including the brass ferrules on paintbrushes and airbrushes), blackens aluminum, and should not be used on wood
Isopropyl alcohol, AKA rubbing alcohol
Both non-porous surfaces (including plastics and unvarnished, unpainted wood) and clothing
Has no common side effects, but infrequently causes irritation and redness on skin. As with all of these products, avoid topical contact
Non-porous surfaces, including plastics and unvarnished, unpainted wood
Contains methanol (a poison)
Non-porous surfaces, such as glass and metals. This is so strong it will not require much scrubbing (perfect for airbrush nozzle tips)
Gives off intense fumes—use in a well-ventilated area. Not safe for plastics or synthetic fabrics
Non-porous surfaces, such as glass and metals, and unvarnished, unpainted wood
Toluene and methanol are toxic; toluene can have long-term health effects. Look for thinners that contain ethyl acetate instead of toluene. Not safe for plastics
Note on Removing Acrylic Paint From Wood
Alcohol, acetone, and lacquer thinner should work on bare, unvarnished wood. If the wood is varnished and gets acrylic dried on it, then hot soapy water is the only way. Although alcohol will not strip varnish per se, it may dull the shine or discolor it.
1: Ammonia Solution
Good old cheap household ammonia is quite effective in removing semidry and dry acrylic paint from non-porous surfaces, such as metal, glass, and plastics. This is because ammonia is often used to stabilize acrylic emulsions by raising the pH. The sudsy variety might actually be best since it contains detergent to keep the loosened particles suspended for easier rinsing.
Be careful as the fumes can be intense. It might be best to clean with ammonia outdoors or under a fume hood or similar fume-extraction device. It's rare, but the fumes can also cause an allergic reaction.
Also, it bears mentioning that ammonia should not be used to clean airbrushes or regular paint brushes. It dissolves brass—including the brass plating on the ferrules of brushes—and blackens aluminum.
2: Rubbing Alcohol
Rubbing alcohol, also known as isopropyl alcohol, is effective in removing dried acrylic from not only non-porous surfaces but also clothing with a little elbow grease. It is another cheap and readily available cleaning solution. The 99+ % concentration works best, but that concentration needs to be ordered online.Unlike ammonia, this liquid actually has some solvent action on the acrylic binder. Small stains on cotton and other natural fabrics should come out if they are soaked, then agitated with an old toothbrush.
How to Remove Acrylic Paint from Clothing With Rubbing Alcohol
Step 1: Gather Your Materials
You will need rubbing alcohol (the higher the concentration, the better) and a butter knife or old toothbrush.
Step 2: Soak the Dried Acrylic With Rubbing Alcohol
First, test the rubbing alcohol on a spot of the fabric that's not usually visible to make sure it will not remove any of the dye (this is uncommon, but it is always best to be safe). Then soak the paint stain with rubbing alcohol.
Step 3: Scrape off the Paint
Let the stain soak for about 15 minutes. By that point, the rubbing alcohol will have loosened the paint, so now you can scrape it off. Use your butterknife or toothbrush to separate the paint from the material.
Step 4: Repeat
Each time you do this, some of the paint will come off. It may take several applications to get the paint off entirely. For this sweatshirt, three applications were needed in order to remove the paint entirely.
3: Denatured Alcohol
Something that is a little stronger than isopropyl alcohol (rubbing alcohol) but still safe on plastics is denatured alcohol.
Denatured alcohol is stronger than isopropyl alcohol for two reasons:
- It does not contain water, unlike rubbing alcohol.
- It is composed of ethyl and methyl alcohol, which are stronger solvents than isopropyl alcohol.
One word of caution, though: Denatured alcohol contains methanol, which is a strong poison. Also, as with all alcohols, denatured alcohol is quite flammable. It burns with a very pale blue flame that is invisible in sunlight. Good ventilation and fire prevention are essential.
A stronger option would be acetone. Unlike alcohol, this powerful solvent cannot be used on plastics or synthetic fabrics. It really is only for getting into hard-to-reach areas where scrubbing is not possible. Acetone-safe surfaces are mainly nonporous, such as glass and metal. It is extremely flammable but low in toxicity. Most hardware stores, paint stores, and home improvement centers carry acetone in metal tins. Acetone is a common solvent used with fiberglass resins. I soak airbrush nozzle tips in acetone when they get gummed up with paint.
5: Lacquer Thinner
Lacquer thinner is a stronger solvent blend that would remove acrylics effectively from glass and metal. Unfortunately, lacquer thinner often contains toluene and methanol, which are toxic. Toluene is capable of long-term health affects. Lacquer thinner should only be used outdoors. Newer "green" formulations of lacquer thinner have eliminated toluene and replaced it with ethyl acetate, a low-toxicity solvent with a pleasant, fruity odor.

Questions & Answers
Question: How do I get acrylic paint off balcony floors (tiles)?
Answer: Ceramic is fairly durable. You could use lacquer thinner on dried paint. Let soak for 5 minutes first.
Question: How do you get acrylic paint off of paint brushes?
Answer: I would soak them for a couple hours in lacquer thinner. Other wish hot soapy water or ammonia water would be good for wet paint.
Question: I have a German ceramic vase which someone has sprayed with gold paint. Can I use acetone on this?
Answer: You should be able to. Lacquer thinner is good too and it dries a tad slower leaving your more time to work with it.
Question: How do I remove spattered, dried acrylic wall paint from an old oil painting without damaging the painting?
Answer: Acrylic should not adhere to oil paint too well. Try dabbing affected area with a rag soaked in either denatured alcohol or isopropyl rubbing alcohol. Remember, you're doing this at your own risk.
Question: I made a big mistake on a corner of a white canvas. It made the whole painting look terrible. It's about 2"x3". I want to remove it and paint white over it with a just a tiny marking of black to finish it. What do you suggest?
Answer: Just paint right over it. Use a Little gesso or primer first if color change is drastic.
Question: I have an antique walnut armoire that has stenciled designs on the door panels. What would be best to use?
Answer: So tricky. I really can't recommend anything due to the delicate nature of antiques. If you're brave, test an inconspicuous area on the furniture with denatured alcohol to see if the varnish or stain can withstand this. Might not even work anyways. If you know the finish applied you can sand everything down to bare wood and refinish.
Question: I used artist’s acrylic paint to produce a union flag on the metal garage door, but vinegar doesn’t touch it. Do you have any suggestions?
Answer: Not only is this a vertical surface but it’s very large as well. Normally, lacquer thinner would be used on a metal surface but the scale of this would not be cost effective as several applications of solvent are probably needed. Therefore, I should recommend the handy heat gun and a putty knife. Any easier method would be to simply spray a white primer for metals over the painted design. Then apply an exterior paint finish that matches the original color of the garage door.
Question: We have two small spots of kids acrylic paint on our outdoor pavers. Which products can we use?
Answer: You might want to apply acetone or lacquer thinner to the paint spots and let them sit for 5 minutes. Use a putty knife to scratch off. A heat gun or boiling water may or may not work also.
Question: I painted a table top with acrylic paint and later used a clear acrylic sealer. It left white streaks over paint. How can I clean the sealer off without damaging the paint?
Answer: You really can’t. You have to strip it all off.
Question: I painted my calculator with acrylic paint. When I removed the paint, you can see the faded paint in the center from where I painted. I rubbed it with a cleansing wipe but it just doesn’t remove it. I rubbed it with acetone. It later dried and it kinda has an appearance of frost. How can I fix this?
Answer: You can’t repair it. Acetone, along with other harsh solvents, irreversibly damages several types of plastics. If it’s a smooth plastic surface you might try sand paper of 300, 600, then 1200 grit. Afterwards, you can just use a polish safe for plastics and buff it out. If it’s textured surface you are up a creek.
Question: I normally use a pouring medium to create different textures in my paintings. How can I remove that from a canvas? I wish to gesso all over it but the pouring medium has dimension!
Answer: Trying to remove acrylic paint deliberately applied is a different matter. You can try applying lacquer thinner and letting it set but it will likely just be a sticky mess.
Canvas is cotton so it be OK you use paint remover and let it sit 15 minutes. Very carefully use a plastic putty knife and gently remove paint. Clean off residue with alcohol or acetone. Let dry then gesso.
In your case I would just remove the dimensional portions. Clean off chemical residues. Go from there.
Question: I just did a portrait on pastel paper, with soft pastel and colored pencil. I did a bit of acrylic splatter for an neat effect, but I 'm not fussy on where one of the splatters landed. How can I safely remove it? I'ts only about 1/4 inch in size.
Answer: You might ruin the paper trying to remove the acrylic. If it is that small it would be easier to just paint over it with titanium white or whatever color the paper is.
Question: How I can remove artist acrylic colour (used for retouching) from an oil painting on jute canvas?
Answer: If the acrylic is already dry then no. Anything that would remove dried acrylic would at least damage oil paint. Your best option is to try to paint over it. I’d put a primer over the acrylic and try using oil paints again.
Question: I have some acrylic paint that I painted on board that I want to scrape down, re-gesso, and re-use the board. What is the best product to use? Is there any reason ZipStrip wouldn’t work?
Answer: Sure Zip-strip will work for this purpose but it might not be needed. If the old acrylic is not textured then scratching fine sandpaper should be sufficient treatment, then gesso over the matte surface.
Question: How can I remove acrylic colour from marble flooring?
Answer: First, marble cannot be treated with ANY acid or acid-containing product. Now with that, I would say put either denatured or rubbing alcohol on the acrylic and let it sit for 15 minutes. Then use a scratch-free sponge. Marble is kind of soft as a mineral and would scratch with harsh treatment. Once removed, you can then use a marble polish to bring the shine back.
An even safer bet would be to soften the acrylic with steam if you can rent the necessary equipment. But for simplicity, the alcohol and scratch-free sponge would be the fastest and cheapest way.
Question: What would work best to get paint off my canvas vans shoes?
Answer: Dab on some isopropyl alcohol. 91% or stronger would better. Let it sit then dab off.
Question: Would isopropyl alcohol remove dried acrylics from a silicone mat?
Answer: Absolutely! But almost nothing sticks to silicone. Try first to peel some of the acrylic off. Then use the alcohol on any stubborn remnants.
Question: How do you remove acrylic from vinyl flooring?
Answer: Well, solvents are out because of the vinyl. So instead you will need an ingredient that will loosen the adhesive bond of the acrylic emulsion. Try soaking area with ammonia for 5 minutes and then use very hot water or steam. Other alkaline substances can be also tried like boiling water with baking soda in it.
Question: How can I remove dry emulsion paint from a bucket?
Answer: Is the bucket plastic or metal? In either case, try denatured alcohol first and let it sit before scrubbing. If it’s smooth plastic, a lot of the dry paint may come off by mechanical means.
Question: I have a 5 gallon bucket with a printed image on it. I tried alcohol and acetone. I'm not sure how it was stenciled on. What can I try next?
Answer: I’m assuming it’s and HDPE bucket and there is pretty much nothing you can do with it if you cannot remove what you want with acetone or alcohol. Hot soapy water with some elbow grease is worth a try though.
Question: I painted with acrylic on a glazed ceramic mug and left it to sit for weeks and varnished it. I'm unsure about the design now. If I remove this acrylic paint and varnish with Acetone do you think it will remove it but damage the mug?
Answer: Acetone will not damage ceramics or glazes. It will work fine maybe lacquer thinner would be a tad more effective because of additional solvents.
Question: What products can you use to remove acrylic from a hardwood floor?
Answer: All the products mentioned in this article with the exception of ammonia. If the hardwood floor has an oil or varnish treatment it may be damaged by most solvents. Test a small area first. Denatured alcohol might be less aggressive but will help to remove dried paint.
Question: I used acrylic paint with wooden stamping blocks and mistakenly let the paint dry on the woodblocks. What’s the best way to remove the dried acrylic paint?
Answer: Cautiously try acetone or lacquer thinner if no rubber is present. If the rubber is present, you’ll have tried hot water with detergent.
Question: How can I remove spray paint in my shoes?
Answer: If it’s oil-based alkyd paint, then make a solution of washing soda in hot water. Lightly dab onto spray paint and let it sit for at least 15 minutes. It should soften the paint enough to be rubbed off with warm soapy water.

@maria, I cannot make recommendations if I don’t know what type of material you want to remove the paint from. Metal and wood are simple enough, just use lacquer thinner, acetone or similar. If surface is plastic you’ll need to find out what kind. Some plastics can stand up to solvent use while others cannot.

Jason (author) from Indianapolis, IN. USA on July 21, 2020:
I would first test to see if the paint on the fence is affected by denatured alcohol. If not, then simply use denatured alcohol to remove. If alcohol makes paint chalky, then you will either need to use hot soapy water or repaint the section of fence. For repainting, just sand the overspray section with 220 grit sandpaper and repaint.

How do you get dried acrylic paint that you brushed on with a paintbrush off of a canvas I need help?
Hi Dewy, if I were you I would use rubbing alchol and follow the directions for removing paint from clothing.(if you want to remove all the paint) Otherwise I would use the rubbing alchol and a Q-tip and gently remove just a bit of paint at a time.
Rhonda, MT on February 03, 2019:
I wish i had taken before, during and after pictures or video!
I used rubbing alchol 70%, poured some in the little depressions and waited about two minutes then used a small piece of green scrubby and was totally amazed at how easy the acrylic paint came off.
My friend uses a plastic paint tray, and doesnt clean the tray between colors very well. So the acrylic dries in layers and was never really cleaned except when she used a knife on it to scrape off the dried paint. When she put her tray in the sink i thought id clean it for her and found this page. I am so glad I did! this saved a lot of elbow grease. I won't ever forget about using alchol on the plastice, I'm sure it would work wonders on glass and ceramic paint trays as well.
Thank you so much Jason for writing up this article. It is definately a finger saver!
Gabriel on December 30, 2018:
Ei Jason! Thank you so much for the reply!
I don't know if the paint is acrylic, its the original paint of the sunglasses, and its quite solid and have a kinda glossy finish. I've tried alcohol on it, but, it did'nt worked. I have to try the hot water yet, bu i think its not strong enough though.
If its not acrylic, do you think that acetone or lacquer thinner would work? I think it need something very strong to remove this paint!
Sorry about the english, not my first language!
Jason (author) from Indianapolis, IN. USA on December 29, 2018:
@Gabriel- If we are talking about acrylic water based emulsion paint then rubbing alcohol should be OK. Do not use Acetone or lacquer thinner though. I am assuming the acetate glass is smooth, you might even get it off with boiling hot water with dish soap since acrylic does not adhere to plastic well. BTW, I do a small test with isopropyl (rubbing)alcohol with Q-tip to make sure first that it wont dull or mar the plastic before going for it all the way.

Jason (author) from Indianapolis, IN. USA on June 01, 2018:
Yep if you leasing be sure its alright to do that in the lease contract. My article was advocating removal of artist acrylic from clothing and carpeting. I mainly was talking about minor amounts. Some of the liquids I suggested are extremely flammable or noxious and once you are working with an area larger than the palm of your hand, the danger increases exponentially. For very large areas like a whole studio, Id have a pro do it and it would removed via mechanical means.
Mike on May 29, 2018:
Hi Jason, I am about to move into a large studio with concrete polished flooring. I was going to lay down vinyl to protect it but that will be expensive and require removing the double sided tape at the end of the lease as well. Your article suggests that I could actually likely get a professional to remove the acrylic and re-polish the concrete floor. Is that correct?

I had a new pair of midnight blue Jeans and bumped up against some pink acrylic craft paint and not realizing it I got it on my hand and I got it in 3 more places on my jeans. The jeans have been washed (prior to paint) in detergent and vinegar which I do every wash. I used the recommended solution for getting out the stains (my alcohol is only 70% though) after several tries the paint came out but it faded the blue out of places where I treated. So I still can't wear the pants. Any suggestions on how to get color back in the spots? I thought of doing a spot Dying with Rit or some other fabric dye but I don't want to do it if it will make things worse. Can you help me ? I don't want to loose a $50.00 pair of jeans!
Jason (author) from Indianapolis, IN. USA on May 24, 2018:
Sure no problem. Just make sure to test on a small inconspicuous area first. Carpet is mostly nylon which is not affected by alcohol but make sure the dye wont run or bleed.

Jason (author) from Indianapolis, IN. USA on January 06, 2018:
if its dry then use denatured alcohol or 90%+ isopropyl rubbing alcohol. You could assist the process by softening paint stain with near boiling water first before trying solvents. I cannot recommend lacquer thinner or acetone because I never used them on carpet. If you have a scrap of the carpet or a hidden spot you can see if lacquer thinner will affect it or not. Good luck!

Redoing my 68 Beetle. The previous owners pairing it an awful yellow and didn't tape any thing up including the chrome/aluminum trim on the side of the doors. Finger nail polish remover was my first go to but it's just taking forever. Lots of scrubbing to get it to lift. I'm considering getting stronger acetone maybe from a hardware store. My main question is, do you think I could soak it or will it ruin the chrome/aluminum finish?
jbosh1972 on April 20, 2017:
The problem is that acrylic and latex are nearly the same. Latex is water based paint with acrylic and polyvinyl acetate blended. Premium latex paint is 100% acrylic resin so you pay the price.
I do have good news though. If the walls are not painted with a flat paint you still MIGHT get the acrylic paint off the latex. It is a week old and dry to the touch but acrylics don't lose all there water for 30 days and they may take a year to completely cure! So first, take hot water with dish soap in it and apply to acrylic paint. If still you have trouble mix alcohol and water to 50/50 and be very careful. I would not get any more aggressive than that. If you try both of those without success, you are just better off sanding area flat and re painting over with the latex original color. Good luck.
Karilpg on April 18, 2017:
Thanks for your tips. I painted cabinets with acrylic paint and didn't realize I had accidentally got some paint on the wall, which I am thinking is latex. It's dried for a week. Can I do anything to get the acrylic paint off without removing the latex? Please no sarcastic comments, I know it was a dumb thing to do.

I have been successful using Murphys Oil. Less toxic. If you get it within the first 24 hours, nearly all of it comes out of clothing. I've used this on my plastic tile floor months later with success. For clothing, make a puddle of Murphys Oil on paint stain, let sit, rub in gentle, hand wash rubbing, I imagine if you had an old fashion scrub board it might take less time. My brushes come out like new even after months of abuse. I just soak the over a 24 hour period working oil through the brushes now and then, not nessecary to dilute.

Mineral spirits will not do unless the acrylic was specifically formulated with it. Lacquer thinner or acetone would work. If possible, I would paint over the blemish with a chalk paint or equivalent that can be lightly sanded smooth and color over it.

Hello, can I use mineral spirits to remove acrylic paint from paper? I made a mistake in my adult coloring book and I don't know how to remove the acrylic paint from my page all colored with colored pencils.

Patrick Lambert on February 12, 2017:
I have a polyurethane resin model that I have painted using acrylic paint and an enamel primer. I hate the paint job and want to start over. I tried applying some acetone free nail polish remover onto my model and rubbing the area with a cloth and it works, it brings off the acrylic paint revealing the primer, and if I run harder it brings off the primer.
However, I have read that nail polish remover isn't ideal as it can eat the resin, so then I stumbled upon your article.
Would Denatured alcohol or rubbing alcohol remove the paint and primer without damaging the model? My model has some really intricate detailing and I would like to keep the detail, so would a toothbrush suffice?

I have acrylic based solid stain on my driveway that has been peeling off all over and I'm forced to strip them all off. What is the most economical way to remove them? I have tried soy gel paint remover and that seems to work pretty good but they are very expensive ($2000). I'm going to first try stripping it with a 3100 psi power washer but I'm sure I also need to use a chemical stripper. Thanks.

I was making some titanium white acrylic since I have a pound of 99.5% pure titanium dioxide from my soap making days that I need to get rid of. I actually enjoy getting messy making paint BTW! Anyhow, I discovered, I could scrub my tools and such with a slurry of laundry detergent powder. I will eventually write a blog post or a hub about it.
Vinca Voda on January 10, 2017:
Thank you, Jason. I found this very helpful. I want to add one more thing that anyone can use on dried acrylic . It's not liquid, but it is extremely useful and safe. Regular baby wipes (Pampers) can clean dry acrylic from plastic, glass, laminate, metal, ceramic and any other non-porous material. For textile I use alcohol (as you recommended) and warm water and it works. I wish there is something affordable for brushes. Ideas? I teach art. Thanks, again.
Jason (author) from Indianapolis, IN. USA on November 29, 2016:
I am glad that you got alcohol to work. It is a fluid that is mild enough to be manageable but it is still flammable. Although acetone and lacquer thinner are far more active, their fumes are a nuisance especially indoors. Those drastic solvents are a last resort really.

I placed some folded sheets I used for drop cloths over the back of my "leather-like" futon, thinking any drops of acrylic paint residue was dry. They ended up sitting there for about 4 days. When I picked them up to put them away, I found that wet paint transferred to the futon; it covered and area if about 6 sq.ins. Some appeared wet so I squirted it with liquid soap and used a scrub brush. There was still a lot of dried paint remaining. After reading this article, I applied the rubbing alcohol to a coarse cloth, rubbing spots in as circular motion. The paint came right off! I want to kiss this author!

I have no idea. How is the leather bonded? Acetone or lacquer thinner will dissolve most glues. Anything strong enough to dissolve leather will dissolve human flesh so beware.

What can I use to remove bonded leather?

If water is working a little bit then you are in luck. So long as the brown paint is not allowed to fully cure, I would try adding a bit of dish soap( few drops) to hot water. If that is still not satisfactory, cautiously start adding alcohol to water in increasing ratios but do not damage underlying white paint. Start with a mix of 80% water and 20% alcohol and work from there.

Help! I painted a brown tree on white painted closet doors and I'm trying to get it off. Water works a little bit, but is there a faster way I can get it off??
Jason (author) from Indianapolis, IN. USA on October 26, 2015:
@Randy, Plastics is kind of tricky. I would try denatured alcohol in an inconspicous test spot first. Other options would be ammonia and water at 200 degrees.

I am trying to get off an air brushed muriel off of the top of a car headliner. It looks like plastic. What is the #1 thing that will get it off? Please help!

Once an acrylic paint had dried it is already cross linked. You will be able to dissolve dried acrylic paint with solvents like acetone but it will not work properly as a paint. I wrote this hub merely to help people remove small stains from clothing and furniture

A Bucket Of Acrylic Paint I Wnt 2 Used Is Totally Blocked,what Will I Use To Dissolve It So That I Will Use It To Paint My Store,help Pls?
Jason (author) from Indianapolis, IN. USA on March 24, 2015:
Hopefully the tank of the motorcycle is painted with polyurethane. First try hot soapy water and a sponge. If that fails try ammonia but test a small area first.

Please help! On my motorcycle tank there are some white paintings made by using a Schmincke AEROCOLOR acrylic ink pen left by its previous owner. I want to get rid of it but it is on tank paint and I want to preserve that without any damage. Problem is, I assume, that layer underneath acrylic letters that I want to dissolve is probably also acrylic so any effort will end up with damage on the tank paint surface. Am I right? Is there some possible way how to do it? Thanks!
Jason (author) from Indianapolis, IN. USA on February 12, 2015:
silicone rubber should be easy enough to remove acrylic paint. I would try soapy hot water and if that fails, denatured alcohol.
Aisyah on February 10, 2015:
Hello, what solution should i use to remove paint on silicone rubber surface? I assume that the paint used on the silicone is acrylic paint too? Please help me!

HDPE or PET plastics are satisfactory for handling acetone.
Jason (author) from Indianapolis, IN. USA on June 25, 2014:
Acetone would work but it will take considerable time. This solvent evaporates very fast. You might try Methyl Ethyl Ketone or Lacquer Thinner. The later two are more toxic so take precautions.
Jason (author) from Indianapolis, IN. USA on June 25, 2014:
That is complete nonsense. Acetone is a by-product of carbohydrate metabolism. Acetone is probably less toxic than ethyl alcohol.
Leander on November 23, 2013:
Painterman, acetone will do the trick with ease. I'm not sure how much you would need for a 90cm cube, but when buying it in larger quantities the price per litre drops to laughable lows. I think the more difficult question will be what kind of container you would need to use for the project as acetone attacks most of the plastics available.
painterman on September 11, 2013:
I've got this art project I'm working on that requires me to dissolve a piece of paint that's roughly a 90x90 cm cube does anyone know anything that will dissolve a solid block of acrylic paint?
rc on June 17, 2013:
acetone is dangerous. 1/4 tsp in a football field 1 foot deep in water is unsafe
Eric on April 23, 2013:
I have plastic pump sprays with dried acrylic wood stain inside the container, nozzles and hoses. Do you think the thinner will be successful or is it likely that these sprayers are shot? Should I use straight thinner or a ratio will water? Thanks
RTalloni on March 05, 2013:
Thanks much for I seem to get it everywhere when I paint!
Wayne Tully from Hull City United Kingdom on October 30, 2012:
Very useful this...cheers now!
Jason (author) from Indianapolis, IN. USA on August 19, 2012:
What? That is lazy mans talk. You must be made of money! Personally, dried acrylic paint is one of the easy things to remove. Try removing ink stains. So far isopropyl is the best thing for ink and it only works to remove 75% of the stain!
Ernesto Bueno on August 17, 2012:
Too much work. Get rid of the jeans and buy a new pair.
Rachel Koski Nielsen from Pennsylvania, now farming in Minnesota on July 19, 2012:
Voted up, useful, interesting. Nice work! I love painting and I'm always making such a mess with it, this info will be really useful to me next time I catch the bug to paint ;)
Jason (author) from Indianapolis, IN. USA on June 30, 2012:
Thank you. The thing to keep in mind is that acrylic paint is an acrylic polymer emulsion. If the paint is still tacky then solvents that mix with water like acetone and alcohol work. For completely hardened paint, acetone or lacquer thinner work best. Ammonia is not a solvent but a reactive medium. It is alkaline or high pH and reverses the polymerization of the acrylic.

I spent a lot of time searching the internet for options to remove dried acrylic paint from plastic sheeting. This article is by some margin the best researched and best presented of any that I found.
