The best way of course is to keep the glue off your
fingers in the first place. If you apply some lotion to your
hands before using Miracle Glue, this will go a long way in keeping
you from gluing your fingers together.
Per the MSDS (Material
Data Safety Sheet) one can use warm soapy water if you get Miracle
Glue on your skin. It seems that this makes the skin sweat and
the oils in the skin slough off the glue. Soak your fingers for
a few minutes in warm soapy water. You can also use acetone or
nail polish remover with acetone in it to remove the glue.
Acetone will also break down the glue if you need to get something
apart. I prefer the soap and water as I don't like to use
acetone. I also would suggest for very dry skin to use some skin
cream before using the glue as there aren't as many natural oils to
protect your skin. Usually, when I'm doing a show demonstrating
the glue I get some on my fingers. Normally, this is completely
worn off within 12-24 hours.
