Be careful if you have special coatings or don't want your items damaged in the process of removing the Super or Krazy glue. Acetone or Nail polish remover is recommended by the manufacturer but may damage your item as well.
If it is a glass or a shiny surface I would try scraping with a razor blade. Remember eyeglasses may have coatings that will be damaged.
For fabric let the glue dry then try to crumple it out.
Super Glue/Krazy Glue aka cyanoacrylate, may have a chemical reaction with many substances and actually becomes part of it. That is one of the reasons why it works so well.
