Takes the guesswork out of cleaning. Spray on the penetrating blue foam and OxiClean Stain Fighters go to work on contact, breaking up soap scum and hard water stains. When the foam turns white, just wipe and rinse to reveal a brilliant shine. Cleans with a fresh scent and no obnoxious fumes. Also removes dirt, calcium, lime, grease and grime. Great for use on tubs, glazed ceramic tile, fiberglass, shower doors, vinyl curtains, sinks, countertops and chrome fixtures.
