Oh my... My husband decided to do a project involving super glue. He managed to drip some inside our copper sink. I can't get it off the bottom of the sink. Any ideas?
Acetone...or the old-fashioned nail polish remover which contains acetone will remove super glue.
When it dries it's generally quite brittle - a razor blade might get it up quickly.
Really hot water might release it also. I like circus's idea with the razor blade.
Is your DH alive or on a wanted poster right now! It is fixable, so hopefully you can forgive him :-)
