BIC Wite-Out, known generically as whiteout, liquid paper, correction fluid or error cover up, stains or dirties glass in a variety of ways. Typically, the Wite-Out stain is the result of a spill. In some cases though, people use Wite-Out as paint to decorate surfaces, including glass desktops and cell phones. Whatever your situation, glass is a surface that you can clean Wite-Out from with little effort using household glass-cleaning products. The exact type of products and the way you use these products depends on several factors, including if the stain is wet or dry, or water or petroleum-based.
Scrape away as much of the stain as possible. If you're dealing with a dry stain, scrape the Wite-Out away with your fingernail or place the edge of a narrow or wide razor blade scraper at a 30-degree angle to the glass in front of the stain and carefully move the blade forward through the stain to scrape it away. If you're dealing with a wet stain, skip this step.
Spray glass cleaner on a Wite-Out stain or if you're dealing with an electronic device, spray the cleaner on a soft, lint-free microfiber cloth or cotton ball and then lay the damp cloth or ball against the stain. If you're cleaning up a water-based Wite-Out stain, spray it with any type of commercial glass cleaner. If you're cleaning up a petroleum-based Wite-Out stain, spray it with a citrus-based glass cleaner.
Wait five minutes for the cleaner to break down and dissolve the stain and then wipe the cleaner and stain from the glass with a damp cloth. If necessary, repeat the process -- dissolving the stain and wiping it away -- until you've removed all of it. When finished, dry the area thoroughly with a microfiber cloth.
