CLR 26 oz. Brilliant Bath Cleaner is a multi-purpose, multi-surface cleaner that tackles dirt, calcium, lime, hard water deposits, and soap scum with its powerful foam spray. It effectively cleans ceramic tile, shower doors, sinks, bathtubs, white grout & caulk, toilet bowls, fiberglass, and kitchen countertops. However, it's not suitable for vinyl, marble, mirrors, plastic laminates, wood, fabrics, painted surfaces, colored grout, or wall coverings. Recognized by the EPA's Safer Choice Program, it's a safer alternative to harsh chemicals, free from phosphates, ammonia, or bleach. Always perform a spot test in an inconspicuous area before general use.
