Tub, Tile and Sink Cleaners
These specialty products are formulated to remove not only the normal soils found on bathroom and kitchen surfaces, but also hard water deposits, soap scum, rust stains and discolourations due to mould growth, which are common to these areas.Tub, tile and sink cleaners are usually liquids. They are marketed as dilutable liquids, trigger sprays and aerosols. Because many soiled surfaces are vertical, some sprays are dispensed as foams to prevent excessively fast run-off of the cleaning product.Almost universally, such cleaners contain surfactants to penetrate and loosen soil. In addition, they may contain special sequestering agents and specific solvents to dissolve and keep calcium (hardness) deposits, soap scum and metal discolourations in solution.Products designed to remove mildew stains may also contain an oxidant, such as sodium hypochlorite, antimicrobial agents to attack mould and mildew, and alkaline ingredients, such as sodium carbonate, sodium silicate and sodium hydroxide.
Depending on the soil, both acidic and alkaline conditions promote cleaning. Tub, tile and sink cleaners which target soap scum and water hardness deposits may contain acids, such as hydroxyacetic or sulphamic acids, in addition to the ingredients mentioned above.
