Calgon prevents limescale build-up in your washing machine and protects its vital parts (heating element, drum, plastic pipes).

It is absolutely safe for all types of fabrics and has a unique phosphate-free formula.

Unlike other tablets, only Calgon contains active ingredients that dissolve within the first seconds of the wash.

Then, the blue and white layers dissolve throughout the washing cycle, providing complete protection from limescale in your machine.
