To get Krazy Glue off the hands, use acetone to dissolve it. Acetone is the active ingredient in nail polish remover.
The Krazy Glue bond can be very strong, so skin that gets glued should not be pulled on in an attempt to force-break the bond. This can damage the skin.
Use an acetone-coated cotton swab to apply acetone directly to the glue, or soak the glued area in a puddle of acetone. Wait until the bond begins to weaken, this can take a few minutes, so be patient. Rinse the area thoroughly.
If acetone is not available, soak the bonded area in warm, very soapy water, and gently work the skin to break the bond.
