You can remove screen print paints from glass without causing any permanent damage. Window pane manufacturers sometimes screen print information about the glass or the company on the window. Car dealers and customisation companies often screen graphics and text directly onto the glass of a vehicle. These identifying markers can detract from the quality of the view through the glass. The painted designs can be scraped from the glass completely so it looks as if they were never there.
Mix concentrated liquid dish soap in hot water. Soak a soft sponge in the soapy water. Press the sponge to a small inconspicuous area on the glass. Remove the sponge.
Scrape the glass in the soapy area with a razor blade window scraper. Wipe the soap from the glass with a towel and inspect the glass to make sure that no damage was caused by the scraping. Consult an auto detailing professional if the small amount of scraping removed a film coating from the glass or left permanent scratches. If not damage was caused by the scraper, move on to the next step.
Coat the screen printed design with a layer of soap with the sponge. Hold the edge of the window scraper blade at a 45 degree angle to the glass and apply medium pressure.
Scrape the paint off the glass in single passes. Lift the blade from the glass and set it back down gently to begin the next pass. Wipe the screen printed image with the soapy sponge repeatedly to remove scraped paint and lubricate the surface.
Clean away all the soap and paint pieces with a clean towel. Spray glass cleaner all over the surface of the glass. Wipe off the glass cleaner in a quick circular motion to leave the paint-free window sparkling.
Always use a brand new razor blade in the window scraper. Most scrapers allow you to quickly switch in a new blade.
Never scrape a window surface with contact tint film on it. Film is usually applied to one side of the glass only.
