Vinegar is an effective stain-removing agent found in virtually every home. It removes anything from oils to grease. But, can vinegar remove paint?
Vinegar doesn’t remove paint completely. The solvent is a mild acid that softens both water and oil-based paints making it easier to scrape off or remove the paint from several surfaces including glass, plastic, and wood.
Vinegar is usually classified as a paint remover because vinegar has traces of ethanol which is a key ingredient in making paint-removing solvents.
However, you should know that vinegar can be corrosive to sensitive materials like rubber, wool, and even metal. This is because vinegar is an acid. So it’s always a safe bet to dilute the vinegar before using it to remove paint from such surfaces.
But that’s not all. There is more to know about using vinegar to remove paint. For instance, Will vinegar dissolve dried paint? Let’s find out.

Will Vinegar Dissolve Dried Paint?
Vinegar will dissolve dried paint. For oil-based or water-based undercoat, paint, or sealant that has cured, undiluted vinegar will soften and dissolve the paint.
This is because vinegar is an acetic acid that is produced from the oxidization of ethanol by acetic bacteria. Ethanol is a key ingredient in the manufacturing of alcohol-based paint removers and solvents. The slight concentration of ethanol in the solvent coupled with the fact that vinegar is an acid means vinegar can dissolve and remove dried paint easily.
You should know that oil-based sealants especially those that are moisture-resistant can be tough to remove when the sealant has cured. You can bypass this problem by using undiluted vinegar to kickstart the removal of such sealants.
Undiluted vinegar will soften the dried coating making it easier to scrape it off with a paint scraper or putty knife. However, you should know that undiluted vinegar can be very corrosive and should be handled with care.
How Long Does It Take For Vinegar To Remove Paint?
It takes between 10 and 20 minutes for vinegar to remove paint. Vinegar when applied needs to soak in the paint coating for a few minutes and then dissolve and soften the paint to make it easier to scrape off. On average, it will take vinegar 15 minutes to remove paint.
You should know that the time it takes for the vinegar to work depends on the type of paint, how dry the paint is, and the concentration of vinegar applied.
Every paint-removing solvent takes time to remove the paint from the surface. For vinegar, it takes between 10 and 20 minutes. Vinegar removes water-based paints faster than oil-based paints.
That’s because water-based paints have a lower level of oils and chemicals making it easier to soften and dissolve. On average, vinegar will remove water-based paints in 10 minutes.
Oil-based paints however take longer. On average, it takes vinegar 15 minutes to remove oil-based paints due to the high concentration of oils and chemicals in the paint.
Oil-based sealants take longer and can take up to 20 minutes to be removed completely. You should also know that the more coats of paints were used, the longer it will take the vinegar to soak into and dissolve the paint.
Also, cured paints will take longer to be removed. Fresh or wet paints however will come off very quickly usually in the first minute. Now that you know vinegar can remove paint and how long it takes, let’s check out how to carry out the process.
How To Use Vinegar To Remove Paint (Made Easy)?
Removing paint with vinegar isn’t difficult. But you should exercise caution and care because the wrong application can ruin the material or surface underneath the paint. To remove paint with vinegar, you’ll need the following tools and supplies:
- A bottle of distilled vinegar
- A pair of gloves
- A paint scraper or putty knife
- A bucket of warm water
- Clean rags
- A clock or timer
Here is a quick rundown of how to remove paint using vinegar:
- Mix equal parts of hot distilled vinegar with water
- Dip a clean rag in the mixture and dab the paint
- Scrape the paint off after a few minutes
- Wipe the surface
Now, let’s get to work.
1. Mix Equal Parts of Vinegar With Water
The first step is to dilute the vinegar. This is an important step as vinegar is an acid and it’s not advised to use it directly. For oil-based paints and sealants, you should mix equal parts of vinegar with water in a clean bucket. This is because oil-based paints are tougher to remove and you need a stronger solution to do so.
For water-based paints, you can mix the vinegar and water in the ratio 1:3 (one part vinegar to 3 parts water) since water-based paints are not difficult to remove.
Most people tend to boil the vinegar before mixing it with water to increase its potency. Though you can boil vinegar, you shouldn’t. This is because the acetic acid in the vinegar will evaporate while behind heated.
And, if this is done in a poorly ventilated room, the steam can be dangerous if inhaled. Also, boiled vinegar is usually very corrosive. To be on the safer side, just mix the vinegar with water.
2. Dip A Clean Rag In The Solution
After mixing water and vinegar, dip a rag in the mixture and let it soak. Then take it out and use it to dampen the paint. When this is done, leave the paint for 15 minutes.
3. Scrape The Paint
After 15 minutes, use a paint scraper or putty knife to remove the paint from the surface. The vinegar would have softened the paint coating so it would be much easier to scrape off. Ensure to scrape off as much paint as you can from the surface.
Sometimes, you don’t have to wait 15 minutes before scraping the paint especially while dealing with water-based paints. If you see the paint starting to melt, turn liquid, discolor, or you see bubbles in the paint coating, you can scrape the paint then. All these signs show that the vinegar has dissolved the paint so it can be scraped.
4. Wipe The Surface
Wipe the surface with a clean rag and soapy water. For porous surfaces like wood, don’t pour the water on the wood as it can soak into the wood. It’s best to dampen a rag with soapy water and use it to wipe the surface. This step helps to clean the material so it’s ready for prep work and painting.
Does Vinegar Remove Stains?
Vinegar removes stains from different materials. The chemical makeup of vinegar makes it able to soften and remove stains easily. Vinegar can remove both water-based and oil-based stains from wood, plaster, or concrete.
However, you shouldn’t use vinegar to remove stains from porous materials or materials that can suck the vinegar. This is because vinegar can damage these materials causing discoloration and etching. So it’s a good idea to dilute the vinegar before using it to remove the stain.
Does Vinegar Remove Paint From Concrete?
Vinegar does remove paint from concrete surfaces easily. On average, vinegar will remove paint from concrete in less than 20 minutes.
Not just that, vinegar is safe to use on concrete as there is a low risk of corrosion, etching, or discoloration of the concrete material.
To remove vinegar from concrete, you’ll need to dilute the vinegar and then apply it to the paint. After a few minutes, you can wipe the paint off.
You should know that concrete surfaces are usually uneven and rough so scraping the paint can be tough as you won’t be able to get all the paint out. So it’s always a good idea to let the vinegar sit for long periods on the concrete to make it easy to wipe the paint off.
Does Vinegar Remove Paint From Wood?
Vinegar can remove paint from wooden surfaces but the concentration of the vinegar has to be heavily diluted.
Also, vinegar shouldn’t be used for long periods on porous wood like Maple, Buckeye, and Alder. This is because the vinegar can easily soak into the porous wood and cause discoloration.
To remove paint from wood using vinegar, you need to mix the vinegar with water in the ratio of 1:3. Then dip a rag in the mixture and dampen the paint on the wooden surface. Don’t pour the vinegar on the wood as that can cause the wood to soak up the vinegar.
Does Vinegar Remove Paint From Metal?
Vinegar does remove paint from metal but it’s not the best bet for this as vinegar is an acid that can corrode the metal.
Vinegar though a mild acid can still cause discoloration, etching, and corrosion of metal surfaces especially if the concentration of vinegar is high. So it’s better not to use vinegar on metal. Instead, you can use alcohol-based solvents or paint strippers designed for use on metal.
Does Vinegar Remove Paint From Plastic?
Vinegar can remove paint from plastic easily but for dried paint, you’ll need vinegar and a soft sponge to wash the paint off.
However, you should know that vinegar isn’t the safest paint remover to use on plastic especially on a soft plastic. This is because the vinegar in high concentrations can melt plastic or make the plastic material softer.
Overall, vinegar can remove paint from different surfaces. But, you should be careful as sensitive materials can be damaged by the vinegar.
So it’s always a good idea to dilute the vinegar before using it. Also, don’t let the vinegar sit on the surface for too long as corrosion can be caused by this.
