If you've ever boiled the kettle to pour yourself a cuppa, only to be met with a layer of scum on your first sip, than your appliance may be full of limescale.
The calcium carbonate found in water hardens each time you turn the kettle on, which means it needs to be regularly descaled. While there are a number of single use products for sale that claim to strip the hard substance, there are also a number of ingredients that can do the same - and you likely already have them in your cupboard.
According to Mrs Hinch fans, boiling a solution of vinegar and water will descale your kettle in little time. Descaling involves filling your it with the cleaner of your choice with water and boiling it multiple times to get rid of the residue.
