Tough Nut: the hand cleaner that works just as hard as you do. Tough Nut is a heavy-duty hand cleaner that gets the job done without drying out your skin or tearing up your hands. Tough Nut uses only the best natural ingredients: no harmful solvents or pumice included. If you’ve ever worked with grease, paint, oil and other liquids that stain your skin, you know how much of a chore it is to remove the gunk and grime. Popular cleansers either take forever to clean your hands (if at all) or they leave your skin dry and damaged. Enter Tough Nut. We guarantee a better clean or your money back – no strings attached.
