Super Glue is the brand name of a very strong adhesive containing cyanoacrylate that dries almost instantly. It is used to bond almost any surface to any other surface, especially in repairing broken items and in adhering craft projects. In general you can remove Super Glue from most surfaces with acetone, a chemical in some nail polish removers. Acetone melts plastic, however, so don't use it for Super Glue spills on plastic surfaces.
Warm, Soapy Water
Mix a few drops of mild soap, such as dishwashing liquid, with water in a large bowl. The mixture should be fairly sudsy. Soak a soft, clean cloth in a sudsy mixture of soap and water, and apply it to the spot where the Super Glue has spilt. Cover the cloth with plastic food wrap, and tape it down so that the moisture does not evaporate. After three or four hours or more, remove the tape, plastic food wrap and wet cloth. Using a dry soft, clean cloth, dab at the spot where the Super Glue is located. Use a blotting motion, and turn the cloth frequently; do not wipe or rub the spot. The softened glue should come up with the cloth. Repeat this procedure if any Super Glue remains until you can remove all traces of it. Wipe the plastic surface dry with a clean cloth.
Use rubbing alcohol on a cotton ball to soften the Super Glue. Dab the spot with the cotton ball, and blot the softened Super Glue with a clean, dry cloth. Repeat until the glue is removed, and wipe the area with a clean, damp rag.
Scraping or Sanding
Carefully scrape the Super Glue spill with a sharp craft knife or utility knife. It may help to soften the Super Glue with another method first. Take care not to gouge or damage the plastic when you are scraping. Alternatively, use a fine-grit sandpaper and very small, circular motions to remove layers of the Super Glue.
