Cleaning washrooms in hospitality, offices, sports centres, schools and public buildings combines three needs: removing limescale from sanitaryware and taps, cleaning surfaces and maintaining hygiene. This range brings together acid-action limescale removers (spray, concentrated or ready to use), concentrated universal and ammonia cleaners, bleach with detergent, a glass cleaner, biological cleaners with enzymes for organic residues and two references with the EU Ecolabel. Several concentrates are prepared with Instaquim's mixing stations or dilution systems.

Kalin, a limescale remover in spray form, is used neat or diluted at 20 to 40 g/l; Bionet, a universal ammonia cleaner with bioalcohol, is dosed at 10 to 20 g/l; Clornet, bleach with detergent, at 10 to 20 g/l; eqo Sanitarios is applied diluted at 2.5 % by spraying; and Eco Kal, an EU Ecolabel limescale remover, is applied neat and removed with a damp cloth. Each product has a technical data sheet and a safety data sheet (SDS), and Instaquim is the manufacturer.
