Having a nice cup of coffee is what the majority of us do on a daily basis, whether it is a 'wake me up' coffee in the morning, an afternoon coffee with your neighbour or a relaxing coffee after a hard days work. But have you made yourself a coffee using your coffee maker and realised that it doesn't taste quite right? The reason for that could be down to your coffee maker, if you take a look inside your coffee maker you may find deposits, which are off-white and chalky in appearance. These deposits are limescale deposits. If you have limescale deposits in your coffee maker or kettle, then it is time to use a descaling solution to clean your appliances and get them to fully working order again.
