Car Paint Repair: How to Remove Car Paint from Windows

If you have ever done any car paint repair, you know there are two methods you can use: 1) spray paint from an aerosol can, and 2) paint by brush. If you use spay paint, particularly if it is near one of your car windows, or if you are painting on a windy day, there is always the chance of getting paint on your car window glass. If that were to happen, how would you remove it? You can find the answer to that question in the information below.

Things you'll need:

  • Glass cleaner
  • Bucket
  • Scrubbing pad
  • Soap and water
  • Sponge
  • Clean dry rags or towels
  • Razor blade
  • Plastic putty knife

Step 1 – Wet the New Paint

Prepare a solution of water and soap in a bucket, wet a sponge with this soapy solution and apply it to the window with the paint on it. Although this will not actually dissolve or remove the paint it will soften it and make it easier to scrape it off the glass without scratching the glass.

Step 2 – Scrape the Paint

Use a razor blade to scrape off the paint. Hold the blade at an angle with its edge against the window glass where the paint is. Push the blade forward against the softened paint. If you find that the paint is not coming off under the razor blade edge, apply more soapy water, and try it again. Eventually, you should have no trouble removing the paint.

Step 3 – Removing Paint from a Tinted Window

A tinted window will require a different approach to cleaning off the paint. Using a razor blade will most likely damage the tint film. Instead, pick up a plastic putty knife at your local hardware store and use it as you did the razor blade. This should remove the paint without damaging your tint film.

Step 4 – Remove the Paint Residue

In the removal process described above, you will have paint residue on your window glass. This may include tiny paint chips you missed during the removal process. As you wipe away the paint debris with a scrubbing pad you'll find some of these chips still sticking to the glass. If scrubbing them away with the scrubber doesn't work, try the razor blade again. You may have to repeat this process a few times to remove all the paint residue and chips. When you are finished removing the paint debris, rinse off the glass with fresh water.

Step 5 – Clean the Glass

When you've removed all paint debris from the window, dry the glass, using a soft, dry cloth, chamois, or paper towel. Finally, use a good window cleaner and clean the glass with a second soft, dry cloth. For an even better spot remover when cleaning the glass, try using a wadded up newspaper after applying the window cleaner.

With your window now cleaned of paint, check other windows where paint might be stuck on the glass. Use the process as described above to remove this additional paint from your car's window glass.
