In the UK many parts of the country are in hard water areas. The white deposits that build up on kettle elements are perhaps the most instantly recognisable sign of limescale deposits - but they can also be found on taps, showerheads and even in the grout between tiles. And then there are limescale deposits that can't be seen - such as in coffee machines, washing machines, steam irons and the heating elements of babies' sterilisers.
It is recommended that you descale such appliances regularly; the harder your water (you can ask your water company how 'hard' the water is in your area), the more regularly it will need doing. Left untreated, your energy bills will rise (as electricity is used to heat the limescale first) and the sooner the equipment will fail.
Using acid is the simplest method of removing limescale deposits and our citric acid uses the same active ingredients found in fruit and vegetables - most notably lemons and limes!
More Citric Acid may be required initially if limescale has had chance to build up, but after that, use regularly to keep limescale at bay.
