MER-MAID is a heavy-duty acidic cleaner. Very effective at removing lime, calcium, and hard water stains. MER-MAID is great for cleaning toilets, tubs, shower baths, tile, drain boards, porcelain, wash basins, sinks, and urinals. Safe on enamelware and porcelain when used as directed. Take caution with using on calciferous stone such as marble, travertine, or limestone, as acids will etch the stone and make them more porous.
