I don't know if this is the right thread for this but; Today I was making something for my secret reaper victim and got Great Stuff ALL OVER my hands. Soap, nail polish, and vinegar were USELESS. What finally got it off was a product called Pumie Scouring Stick Heavy Duty. This isa pumice stone used for getting rings off of toilets and ceramic basins and tubs. It worked PERFECTLY! Here's how I used it: hold the pumice stick under water to moisten it, wet your hands, and GENTLY scrub with the pumice stone. In less than five minutes my hands that were so sticky I could have dangled from the ceiling with them were absolutely clean.
