Gel Kilrock Limescale Remover Descaler 160ml 5 "It's a dream!" Miss Vaughan Spencer 21 March 2018 This worked perfectly. I love that it's easy to apply and it's thick enough to stay put to work its magic. I used it around the base of my bathroom sink taps, left it for five minutes, then lightly scrubbed it with an old toothbrush and the area came up perfectly clean within seconds. It's great to know I have a reliable product for when scale builds up in the future.
