How to remove limescale from a washing machine
Most homes in the UK have some degree of hard water, which means limescale deposits inside your machine can reduce the efficiency of the washing machine and act as a breeding ground for germs.
As well as cleaning your washing machine, unless you have very soft water, then you should consider descaling your machine regularly. The frequency depends on exactly how hard your water is. As a general rule of thumb, it's a good idea to clean your machine one month and then descale it on alternate months. Both procedures generally involve running an empty hot wash with a product designed for the job.
Limescale build up on a heating element
Removing limescale from the internal parts of your washing machine is relatively straightforward. There are a number of products available on the market and although they can vary wildly in price, they are all merely an acid suitable for dissolving limescale. They are usually based on sulphamic acid or citric acid.
The acid dissolves the limescale, which is then washed away to the drain. Application is simple and usually involves simply pouring the relevant dose into the drum and running an empty load on a hot wash.
