The eco-friendly and chemical-free EcozoneMagnoloo is the anti-limescale toilet descaler of choice. Guaranteed for five years, simply drop one Magnoloo descaler (or two in very hard water areas) into the cistern to keep your toilet free from a build-up of deposits for up to 5 years. The chemical-free Magnoloo can help to prevent or eliminate the unsightly stains of limescale built up in the toilet. How? Well when water is treated magnetically the calcium carbonate doesn\'t form a hard limescale butinstead flows out of the toilet with the water when you flush. The feet of Magnoloo allow it to sit at the bottom of the cistern and allow water to circulate underneath and through it. Alternatively, you can hang Magnoloo with some string or wire into the cistern, using the holes provided.
