If you have ever worked with the black foam for ponds you know it can be a very sticky and messy endeavor. If you get it on your skin there are no chemicals which will take it off. I have tried goop, abrasive hand cleaners, comet, acetone, and various other cleaners. None seem to work completely. Then by accident I came across the magical formula. Digging with your hands in georgia red clay removes the foam. I don’t know if it is the abrasion or the acidity of the soil but it works surprisingly well. Of course then you have to get the clay off your hands which can be nearly as difficult.
Clay does not seem to get it off of fingernails however but that is an easy scrape and file.
