CL400DS Aktivo Dishwasher and Washing Machine Descaler 400g, Limescale Remover for Dishwashers and Washing Machines

CL400DS is a 400g descaler made for both dishwashers and washing machines. Hard water leaves mineral deposits, known as limescale, on heating elements, spray arms, pipes and inside the drum, and a descaler dissolves that build-up. One product covers both appliances, which makes it handy for a kitchen and laundry clean in the same week. Always follow the dosing and safety directions on the pack.

Signs your dishwasher or washer needs descaling

Limescale is the chalky white crust that forms where hard water is heated or dries out. In a dishwasher it shows up as a white film on glasses and the tub, blocked spray arm holes and slower heating. In a washing machine it coats the element and drum, making heating less efficient, and can leave a musty smell or grey residue on clothes. Descaling from time to time keeps water flowing freely and helps heating elements work as they should. Homes with harder water will need to do it more often.
