Walmart offers the Permatex 1-Gallon Fast Orange Pumice Lotion Hand Cleaner with Pump, model no. 25219, for $9.88. (Amazon offers it to Prime members only for the same price.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's slightly under our October mention and the lowest price we've seen. (It's a current best by $4.) This waterless formula is biodegradable and contains no harsh chemicals, mineral oils, or ammonia.
