Calgon 4in1 Washing Machine Water Softener Tablets

Stops limescale building up inside the machine.

If you live in a hard water area, limescale slowly coats the heating element and the drum. That makes the machine work harder and shortens its life.

One tablet goes in with every wash. Calgon's 4in1 formula works on four things at once: limescale, rust, detergent residue and the stale smell a machine picks up over time.

How to use it

Put one tablet in the drum with each wash, alongside your normal detergent. It does not replace detergent.
