How to prevent limescale
Prevention is better than cure, and there are a number of ways you can do this.
Wipe the bathroom after use
Drying water off wet parts of the bathroom will stop it from evaporating and leaving water behind.
Try and soften your water
A water softener can help to reduce limescale. Some options use ion exchange and salt to remove the minerals that cause limescale from the water.
Others alter the chemical so they cannot cling to surfaces.
