Heavy-duty acid bowl cleaner for commercial

This 3M formula contains 23% hydrochloric acid to dissolve rust stains, hard water scale, lime, and organic matter on ceramics, enamel, and metal fixtures. It is sold as a case of 12 ready-to-use 32 oz bottles for professional maintenance teams.

Simple pour-and-scrub application

The liquid is non-flammable and unscented, reducing handling hazards during routine cleaning. Operators should wear acid-resistant gloves and eye protection, ensure adequate ventilation, and never combine this product with bleach or other chemicals to avoid dangerous gas release.

Verify fixture compatibility

Confirm that bowls and urinals are made of acid-resistant ceramics, enamel, or metal; soft stone, coloured grout, or damaged glazing may etch permanently. Check local regulations for hydrochloric acid disposal and ensure the plumbing system can tolerate low-pH effluent.
