Redecker Kessy Limescale CatcherKeep your kettle clean and in top condition with this nifty and environmentally friendly stainless steel limescale catcher. Simply pop it in and it gets to work, collecting limescale deposits with every use. When it has turned white with limescale, remove it, allow to dry, then gently tap to dislodge the deposits and it is ready to use again. Heating elements and the bottoms of your pots stay free of limescale without the use of harmful chemicals.
