Why Pros Choose It

Dissolves Salt & Scale

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

Fume-Free Formula

Strong enough for industrial use but formulated to keep restroom air breathable while you work.

Pipe-Safe

Won't corrode standard plumbing when used as directed. Safe for regular maintenance schedules.

Commercial Grade

Concentrated industrial-strength formula built for high-traffic restrooms — schools, offices, stadiums, restaurants.

How to Use

Full instructions and safety warnings are on the bottle label and in the Safety Data Sheet. A quick summary for planning:

  • 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.

Cleared years of buildup
"Poured it into two urinals that had years of caked-on scale. Left it sit overnight, flushed in the morning, and the water ran clean for the first time since I started here. Ordered the 12-pack immediately."

Works, no headache from fumes
"Every other industrial descaler I've used stings your eyes for hours. This one you can use during business hours and nobody complains. Effective on the scale too, not just gentle."
Verified purchase
Standard product does what it says
"Nothing fancy, does the job. We use it monthly on our restroom floor drains and it keeps them from smelling. Bottle is a good size — one bottle lasts us a couple months."
