Glue residue can happen when using a spray adhesive and overspray sticks to the surface of the surrounding area, or if some of the glue presses out of the section being glued together. To help avoid overspray or over application, place a piece of paper or tape on the project to mask off and protect the area.
If the glue is still wet, use a dry paper towel or Q-tip to remove most of the excess, then clean away with a damp, soapy cloth. If the glue has dried, you can try peeling or rubbing it away, carefully scraping it from the surface with a knife or razor blade, or using a glue remover product like Goo Gone®. You can also try acetone (found in nail polish remover), a high percentage rubbing alcohol (85% or higher) or mineral spirits for solvent-based adhesives such as The Ultimate, Bead & Glass, etc. All Tacky Glues can be removed with an all-natural, biodegradable citrus-based cleaner.
