Why Pros Choose It

Breaks down uric-acid crystals, calcium deposits, and rust that cause slow drains and odor.

Full instructions and safety warnings are on the bottle label and in the Safety Data Sheet. Quick summary:

PPE: Wear chemical-resistant gloves and eye protection.
Application: Pour directly into the urinal bowl or drain. Let it sit for the dwell time on the label so it can break down the scale.
Rinse: Flush thoroughly with water.
Cadence: Weekly for heavy-traffic restrooms, monthly for lighter use.

Do not mix with bleach or other cleaners. Keep out of reach of children.
