If you’ve ever looked inside your kettle chances are you’ve probably spotted a tough, stony, off-white crust at the bottom of it. This is limescale, the deposit left behind by hard water. As Great Britain is largely made up of limestone and chalk, around 60% of homes in England and Wales are supplied with hard water. It’s this formation of scale which in turn can cause damage to household goods such as dishwashers, washing machines, and of course your shower. The most preventable way to treat either a single item or whole house is with a water softener.
