How we uncover the best limescale removers

We’ve tested the most popular limescale remover sprays, including big brands such as Cillit Bang, Viakal, Dettol and Limelite, as well as supermarket-own brands and eco-friendly limescale removers. So when you use a Best Buy limescale remover, you can be sure that it will remove limescale and clean away soap scum better than rival products.

  • Limescale removal – we put limescale removers to work on a rock with the same properties as limescale to see how much they can dissolve. The best remove four times more than the worst.
  • Soap scum removal – we apply each product to tiles laid both upright and flat to check which can remove soap scum from horizontal and vertical surfaces in your bathroom, and which leave behind scum and streaks.
  • Surface care – we leave limescale remover on 10 different kitchen and bathroom materials for 24 hours to check for any surface damage, so you know what would happen if you miss rinsing off a spot of limescale remover.

Limescale remover reviews you can trust
