When Kleen Products decided to create Hand Scrub, the first consideration was to maintain the highest level of quality expected from Joe's Products. A polyethylene scrubber provided the required criteria. Consistent particle size blends evenly and thoroughly. Secondly, the polyethylene is round and smooth, unlike jagged edges of pumice or sand. Subsequently, the scrubbing process is a safer, more gentle method. Treat your hands to a wake-up call with Joe's Hand Scrub.
