By using one of these descaler rings in the cistern, you can keep your toilet free from a build up of scale deposits for up to 5 years. This chemical-free magnetic ring will polarize the calcium, preventing unsightly stains and limescale build up.

Just put one into your cistern and you can cut down on the use of cleaning chemicals. 5 cm diameter.

RRP £6.99, tgtc price now £5.95

Please note: in some areas of very hard water, i.e. London and the South East, it may be necessary to use 2 toilet descaler rings in each cistern for this to be effective.
