This Heavy Duty mechanic’s soap is tough as mud—because it is mud. Bentonite clay, to be exact. Our coarse pumice formula breaks down grease, grime, and gunk to leave your hands cleaner than a Dad joke. Oh, you’re “sensitive”? Relax. All-natural moisturizing ingredients prevent skin of all types from drying out and cracking. Perfect for the home garage or low-traffic wash stations.
