In showers in gyms, swimming pools, hotels, care homes and industrial changing rooms the main problem is limescale build-up on screens, taps and shower trays, together with daily soiling. This range combines acid-action limescale removers (in spray form, concentrates for dilution or for preparation with a mixing station), concentrated ammonia and universal cleaners for routine cleaning, and a high-viscosity descaler for localised scale. The concentrates in the eqo and IQ series are prepared with Instaquim's dilution systems.

Kalin, a limescale remover in spray form, is used neat or diluted at 20 to 40 g/l and, if applied neat, is rinsed with plenty of water; Amonet, a concentrated ammonia cleaner, at 5 to 10 g/l; Brillnet, multipurpose, at 20 to 40 g/l with subsequent rinsing; eqo Sanitarios, diluted at 2.5 % by spraying; and Defort, neat on scaled areas, scrubbing with a brush if necessary. All have a technical data sheet and a safety data sheet (SDS), and Instaquim is the manufacturer.
