Knowing how to remove paint from glass is an important part of any interior painting job. No matter how careful you try to be, it seems that paint inevitably ends up on a windowpane, no matter how carefully you taped it off. Professional house painters and DIYers can use some techniques to safely remove paint without scratching the glass.
Vinegar and water
Using vinegar and water to remove paint from glass is a tried-and-true technique. It simply requires a cup of white vinegar that is heated and brought to a boil (using a microwave is faster). Rubber gloves are recommended when using hot vinegar. Soak a sponge or rag in the hot vinegar and swipe it over the glass pane. Depending on the age of the paint, you may need to use a little more elbow grease, but the vinegar will help loosen it.
Nail polish remover or alcohol
Acetone or nail polish remover, or alcohol are also effective mediums to remove paint from glass, but it will depend on how much paint, how thick, and the area to be cleaned. The key is to protect the existing paint of windowsills and sashes, especially when cleaning after an interior paint or window installation job.
Hot soapy water
Hot, soapy water is also an effective technique for removing paint from glass, depending on how long the paint has been there. As with the vinegar and water technique, wear rubber gloves to protect your hands from hot water when using this technique. Fresh paint will come off rather quickly in most cases. As with the vinegar and water technique, some elbow grease may be required if the paint has dried for some time, but be patient.
The razor blade
Razor blades are an effective technique to remove paint from glass, but if not used with discretion can leave scratches in the glass. For this reason, use a new and sharp blade. Watch your fingers and hold it firmly at the top, placing the blade edge at an approximately 45° angle to the glass. Results may be better if both the windowpane and the razor blade are wet during this technique, but it’s also quite effective when both are dry. If the blade is held too straight or perpendicular to the paint and you try to scrape, you’re more likely to leave scratches on the glass.
When working with a razor blade, move it in one direction or one swipe at a time. Resist the urge to scrape it back and forth across the surface of the paint stain. The ideal result will be if you can manage to get the edge of the blade underneath a drop or section of paint stain and remove it in one clean swipe.
