These ingenious cartridges prevent minerals, germs and fungus from causing stains, rings and limescale build up in your toilet.

To use them, first scrub the bowl, then simply drop one chemical-free cleaner into your cistern. The special 'mineral magnets' will keep your toilet free from deposits for 50,000 flushes or up to 5 years.

Eliminates the need for chemicals. Adds nothing and takes nothing from the water.
Safe for your children, pets and the world environment!

They're quite small (10 x 4cm). For very hard water areas use 2 cartridges per cistern.
