Descaling
Also called: limescale removal, descale, scale removal
Descaling is clearing the build-up of limescale — the hard, chalky mineral deposit that Dubai's hard water leaves behind wherever water is heated or left standing. It collects on heating elements, boilers, valves, spray jets and steam generators in water heaters, dishwashers, glasswashers, combi ovens and coffee machines. The problem is that scale insulates the heating element, so the machine works harder, heats more slowly and costs more to run, and it clogs jets, valves and sensors until performance drops or a fault code trips. Softened or filtered feed water slows it down, but in a commercial kitchen or a hard-water villa the equipment still needs periodic descaling on a schedule — not just when something breaks, because by then the scale has usually already cost you element life. Left too long it shortens the life of the whole machine, which is why regular descaling belongs in a planned kitchen equipment maintenance routine rather than being treated as an afterthought.
