How to Remove Chalk Paint with Vinegar

If you’ve used chalk paint before, you already know that it can produce a beautiful, matte finish on furniture. But there are instances where you may want to remove dried chalk paint from a surface altogether. 

Thankfully, removing chalk paint is possible by using a common household item— vinegar. In this guide, we will walk you through the steps for how to remove chalk paint with vinegar.

KEY TAKEAWAYS

When applied to chalk paint, vinegar helps to break down the paint’s bond with wood furniture, which makes it easier to scrape the paint off. This paint removal method can be much more efficient than manually sanding the paint off.

Does vinegar actually remove chalk paint? 

Yes, vinegar can be an effective method for removing chalk paint. Vinegar is a known mild acid, and as you apply it to chalk paint, this compound may break down the paint’s bond with the surface. Ethanol, a key ingredient in alcohol-based paint removers and solvents, is oxidized by acetic bacteria to produce vinegar. The acidic nature and slight ethanol concentration in vinegar allow it to dissolve and remove dried finishes easily.

The mentioned process allows the paint to be easily removed with a scraper or sandpaper. However, it’s important to note that vinegar solution may be more or less effective depending on the chalk paint brand and the surface the paint was applied to. It’s always a good idea to test a small, inconspicuous area first before attempting to remove the paint from a larger surface.

Using undiluted vinegar can help by softening the dried coating. Eventually, it makes scraping off easier to do with a scraper or putty knife. Nonetheless, undiluted vinegar is highly corrosive and should be handled with care.

Removing chalk paint with vinegar step by step 

Below is the general procedure that you may observe on how to remove chalk paint with vinegar (available here on Amazon). 

Step 1: Prepare the required materials

A quarter cup of white distilled vinegar: This household product is the main ingredient you’ll be using to dissolve the chalk paint. It is vital to have enough vinegar to cover the area you aim to clean.

A sponge, rag, or soft cloth: A cloth will be needed to apply the vinegar to the furniture. Select a soft and absorbent material that won’t scratch or damage the surface.

A paintbrush: Suppose you will deal with a large affected area, a paintbrush can help you apply the vinegar evenly and cover all the nooks and crannies. Use a brush with soft bristles to avoid scratching the surface.

A paint scraper or putty knife: For stubborn paint stains or thick layers of paint, you’ll need a tool to scrape away the residue. A paint scraper or putty knife can help you remove the paint without damaging the surface underneath.

Step 2: Create a vinegar-water solution.

Before you start removing chalk paint using vinegar, you’ll need to mix it with water. This is because vinegar is an acid and direct application can be a bit harsh on wood furniture. 

For oil-based paints and sealants: Mix equal parts of vinegar and water in a clean bucket with a ratio of 1:1 ratio. Oil-based paints are tougher to strip and you need a more robust solution to dissolve them. The vinegar-water solution will help break down the paint and make it easier to remove.

For water-based paints: Prepare a vinegar-water solution using a ratio of 1:3 (one part vinegar to 3 parts water). Water-based paints are not challenging to remove, so a weaker solution might do the job. The vinegar-water solution will be effective in removing the paint without damaging the surface underneath.

It’s important to note that you shouldn’t boil vinegar before mixing it with water to increase its potency. Contrary to popular belief, boiling vinegar will not make it stronger. In fact, the acetic acid in the vinegar will evaporate while being heated, which will make it less effective in removing the paint. Simply mix the vinegar and water in the right ratio and you’re ready to start removing the chalk paint.

Step 3: Apply the solution on the surface.

After you’ve prepared the vinegar-water solution, you are now ready to apply the solution to the surface.

Dip the prepared soft cloth, sponge, or rag into the vinegar-water solution. Allow it to soak for a few seconds, or until it is completely soaked. Wipe the surface with the rag when it has been thoroughly soaked with the solution. You must ensure that any surfaces that have been coated with chalk paint are covered. Wipe with mild pressure to help soak the paint. 

Once done with wiping the surface with the vinegar-water solution, let it sit for 15 minutes. Such time will give the solution the right amount of time to break down the chalk paint, removing it in a breeze.

Step 4: Scrub off the chalk paint.

After 15 minutes, remove the paint residue using a paint scraper or putty knife. Because the solvent weakened the coating, scraping off the chalk paint should be pretty straightforward. Scrape off as much paint as possible from the surface.

When scraping off the paint, take care not to harm the surface underneath. To avoid scratching or gouging the surface, apply mild pressure and work carefully.

Step 5: Clean off affected surface

Once you’ve scrubbed off the chalk paint with a scraper or putty knife, the next step is to clean the affected surface.

Mix a small amount of dish soap with warm water to prepare a soapy water solution. Ensure that the solution is not too soapy, because this can leave residue on the surface.

Dip a clean rag in the soapy water solution and wring out any excess liquid. Use the damp rag to wipe down the surface in removing the remaining residue from the vinegar-water solution. If you are dealing with porous surfaces like wood, be careful not to pour water onto the surface as it can soak into the wood. Instead, use a damp rag to wipe down the surface.

After wiping down the surface with the soapy water solution, you may proceed by rinsing it off with clean water. Again, be careful not to pour water onto porous surfaces. Instead, wipe off the surface with a clean, damp towel to eliminate any leftover soap residue.

Other household products for removing chalk paint

Aside from vinegar here are other home remedies to remove paint from wood:

Baking Soda

This item is usually mixed with water to create a paste that can help remove chalk paint from wood. The paste should be applied to the affected region and left to sit for a few minutes before scrubbing it off with a brush or scraper.

Oven Cleaner

The chemical substance could be useful to remove chalk paint from wood, but it’s important to use caution when using this method. Oven cleaner is known to be highly toxic, so it’s important to wear gloves and protective eyewear and work in a well-ventilated area. The cleaner should be sprayed onto the affected area and left to sit for a few minutes before scrubbing it off with a brush or scraper.

Ammonia

The famous household compound can be mixed with water to create a solution that can help remove chalk paint from wood. The solution should be applied to the affected area. You may deal with the chalk paint via scrubbing with a brush or scraper.

Mineral Spirits

These spirits can be used to remove chalk paint off wood, but they must be handled with caution. Mineral spirits are very flammable and should only be used in well-ventilated areas. Apply the spirits to the damaged region and let it stay for a few minutes before cleaning it away with a brush or scraper.
