MB Stone Care MB-3 Soap & Mineral

MB Stone Care MB-3 Soap Scum & Mineral Deposit RemoverMB-3 Soap & Mineral is a non-acid concentrate that dissolves soap scum and hard water mineral deposits on natural stone, tile, glass and fiberglass. Because the formula contains no acid, it lifts build-up from shower walls, floors, doors, washbasins and bathtubs without the vigorous scrubbing or abrasives that dull a glossy finish.
