How to Remove Paint from Glass

How to Remove Paint from Glass

When you’ve finished painting your wooden windows, you want the paint to be smooth and even. Unfortunately, it can be difficult to keep paint off the glass, and once it dries it can be tricky to remove. In this blog post, we explain how to remove dried paint from the glass without scratching the surface.

Paint can be a great addition to wooden windows. It can add colour and character, as well as protect the wood from the elements.

The first thing to do is clean the surface of any excess paint using a cloth or paper towel. If there are still smears of paint on the glass, try using window cleaner or vinegar and water solution to remove them. Once they are gone, you can start removing the remaining residue with rubbing alcohol. This is a great option if you have painted wooden windows because it doesn’t contain any harmful chemicals that might damage your paint job.

Use a clean cloth and warm soapy water

If you only have a small amount of paint to remove, try using a clean cloth and warm soapy water. Wet the cloth with warm water and wring it out so it’s not dripping wet. Then dip the cloth into some mild detergent (such as dish soap) and start wiping away at any bits of paint that are still visible on your window pane. If necessary, use a second cloth dipped in cold water to remove any soap residue left behind by the first one.

Use glass cleaner or vinegar if necessary

If your window panes aren’t too large or if there isn’t too much paint on them, you can usually get away with just cleaning with warm soapy water alone – no need for anything else. However, if there are still some stubborn bits of dried-on paint around after doing this then consider using an all-purpose glass cleaner.

Once all traces of paint have been removed from your windows and sills, use a lint-free rag with some mineral spirits on it and wipe down all surfaces again just to make sure everything is clean before moving on to step three:

Sanded Paint Removal

Using fine-grit sandpaper to remove dried paint is the most common method for removing old paint from windows. However, it will scratch the glass and leave it looking cloudy.

Use a soft cloth to remove any dust from the surface of your window and then apply masking tape along the edge of the frame where you don’t want to sand. This will protect the surrounding areas from being scratched by your sandpaper.

Begin by lightly sanding over the area with an orbital sander using 80-grit paper. This will help get rid of any loose paint without damaging the surface of your window too much. Then switch to 120-grit paper and repeat until all visible traces of paint have been removed from the area you were working on.

Plastic scraper

The simplest method is to use a plastic scraper, such as a putty knife or plastic credit card. The key here is to use something flexible and soft, so that it doesn’t scratch the glass when it comes into contact with it. A piece of sandpaper can also be used in place of a scraper.

Rubbing alcohol

Mixing rubbing alcohol with water will create an alcohol-based solution that will help break down the paint and make it easier to remove. Dip your rag into the solution and rub over areas where paint has dried on your windows. This should only take a minute or two before you see results. Be sure not to leave any damp patches on your windows, as this could cause damage over time.


There are a few ways to remove paint from glass. Here are a few methods:

  • Use a razor blade. This is the most common method for removing paint from glass. Simply scrape the paint off the glass with a razor blade. Be careful not to scratch the glass.
  • Use a paint thinner. Paint thinner is a solvent that can dissolve paint. Apply the paint thinner to a rag and rub it on the paint. The paint should dissolve and you can wipe it away.
  • Use a commercial paint remover. Commercial paint removers are available at hardware stores. These products are designed to dissolve paint and make it easy to remove. Follow the instructions on the product label.

No matter which method you choose, be sure to wear gloves and safety glasses to protect yourself from the chemicals.

Here are some additional tips:

  • If the paint is old or dried, it may be more difficult to remove.
  • If the paint is on a window, you may need to remove the window from the frame to make it easier to remove the paint.
  • If the paint is on a mirror, you may need to cover the back of the mirror with a towel to prevent the paint thinner or remover from getting on the mirror.
