How to Remove Paint from Rubber or Plastic Window Trim

Nothing is more frustrating than finishing up the perfect window glazing project only to discover that paint has gotten onto the window trim. Harsh chemical paint cleaners and thinners can damage plastic, leaving few options for removal. Here are several options for removing paint from plastic or rubber window trim.

Warm Water

If the window in question has been painted with matte emulsion paint, warm water should go a long way in softening it for removal. Soak a sponge in warm water and wet the paint. If it softens, you may be able to simply wipe it off; otherwise, gently coax it off with the scraper.


If the window was painted with gloss paint, gloss paint doesn't adhere very well to plastic. A scraper alone, in this case, should get the paint off. Be careful not to scratch the plastic.

Rubbing Alcohol

If warm water and a scraper fail to do the job, you can try using rubbing alcohol. Apply a small amount on top of the area where the paint is located. Then wipe the spot off with a damp sponge that has been soaked in warm water and a mild detergent. The paint should be easily removed at this point.
