Super glue refers to an industrial-strength glue that is fast drying and can repair anything from cracks in wood to broken china, glass, split rubber and other issues. However, super glue sometimes has a way of ending up in places where you don't intend it to be, such as your fingertip, clothing or on upholstery. If you think you've permanently damaged a leather couch or chair with a few globs of super glue, don't despair. You can remove the glue without damaging the leather.
Allow the glue a minute or two to dry. It's actually easier to remove glue when it's completely dry. Dip a cotton swab in acetone nail polish remover until the swab is soaked.
Dab the cotton swab on the dried super glue. As you dab, the glue will start to dissolve. gently run a razor blade across the super glue, to nudge it off the couch. Your goal is to have the razor blade make contact with the glue, but not the leather, as it could scratch or cut it. So do this very carefully.
Continue dabbing with your cotton swab and re-dipping the swab into the bottle of nail polish remover. Run the razor along the glue until it is all gone.
Wipe down the area with a dry cotton ball.
