• A professional-strength specialty bowl cleaner that combines ammonium bifluoride, hydrochloric acid, and phosphoric acid for maximum stain-removing power.
• It rapidly dissolves rust stains, gray rings, mineral deposits, and hard water buildup that other bowl cleaners leave behind.
• Intended for occasional restoration of heavily soiled toilet bowls—not daily maintenance.
• Always wear appropriate protective equipment and follow label directions.
• Clear and colorless with a characteristic acidic odor.
