How to Remove Paint Stains From Glass

Updated February 21, 2017

Paint can get on glass surfaces when painting window frames or even by picking up a drinking glass with paint on your hands. Paint on window glass should be removed as soon as possible because heat from the sun can bake the paint stain into the surface of the glass. Removing paint stains from glass is not hard, but care should be taken not to scratch the surface.

Squirt dish detergent into a bucket and fill it with water.

Apply the soap solution to the painted areas on the glass with a sponge. Make sure the painted areas are completely covered. The soapy water creates a slippery film for the razor blade, reducing the chance of scratching the glass surface.

Scrape the paint with a sharp razor blade. Use a sharp razor, as a dull blade may increase the risk of etching on the glass.

Use short scrapes with the razor and do not scrape back and forth. Move the razor with a forward motion, bring razor up from the glass surface, then bring back and scrape forward again. Continue this manner of scraping until all paint is loosened from the surface of the glass.

Apply more soapy water if the glass becomes dry while scraping. When all paint is scraped from the glass, wash with the soapy water to remove all loosened paint specks.

Rinse the window with cool water and dry with a soft, clean cloth.


Do not press hard on the glass with the razor blade. Press only enough to remove the paint. This will help to avoid scratching the glass.
