Painting is a cheap and simple way to give your house a new look. It can be done quickly, and most people find painting to be a fairly easy skill to master. Painting windows, however, can be tricky business. Tape must be applied carefully and paintbrushes must be wielded gently. Unfortunately, paint seems to get on the windows no matter what steps you take to prevent it from happening. Accept it, plan for it and never fear: You can get that paint off your vinyl windows with just a little time and effort.
Scrub off the paint. First, soften the paint by using a washrag to apply warm water mixed to the paint. Gently rub at the paint with the wash rag, re-applying warm water and soap if needed. Try using a rough sponge if the wash rag is too soft to get the paint off.
Scrape the paint off. If the warm water and soap just aren't doing the trick, use a putty knife to scrape off the rest of the paint. Apply light pressure to prevent leaving marks on the vinyl or glass, and use short, quick scraping motions, moving in one direction only. Scraping in different directions might do damage to the window in the form of scratch marks.
Use a commercial paint remover, such as Goof Off. Put on gloves to protect your hands, then apply the solution to the paint and let it sit according to the directions on the container. For small paint areas, use a spray bottle with a diffuser attachment to apply the remover directly to the paint, being careful not to get it on any other part of the window. While these types of paint removers are known to work quickly and very well, some consumers warn that they can also stain the vinyl.
Use an old wash rag to remove the leftover paint and residue, taking care not to inhale the fumes or let any of the solution touch your bare skin. Clean the window thoroughly with soap and water until no trace of the solvent or paint remains.
