Handy ways to tackle Limescale!


Following on from our post about what limescale is and where it comes from, we wanted to give you some handy tips on how to tackle that white crusty substances that lingers EVERYWHERE that’s been in contact with hard water!

It’s important that you tackle limescale and don’t ignore it! It can be destructive, inconvenient and costly and as Water Treatment UK reports, a health hazard –

“limescale deposits can be a breeding ground for dangerous bacteria including legionella bacteria which causes Legionnaires’ disease. This can be a particular problems for shower heads and taps that create an aerosol type spray.”

Although wiping away the water before it settles on surfaces is the best form of deterrent, it’s not always convenient and the inevitable limescale build up can occur. There are a huge range of products on the market that help with reducing limescale, with Viakal & Cilit Bang the most commonly used.

However, there are also some simple home remedies which you can use as well, including malt/white vinegar and lemon juice which dissolve the mineral deposits:

  • washing machine – use a large cup of either vinegar or lemon juice and run a normal washing cycle (without clothes)
  • dishwasher – pour the vinegar / lemon juice liquid into the base of the machine rather than the detergent dispenser and run a cycle whilst machine is empty
  • taps – cut a lemon in half then press it on to the spout of the tap, twisting gently until it stays in place. Leave for an hour to descale.

Although malt/white vinegar and lemon juice are fine for cleaning out your kettle or polishing taps and silverware, it’s only a temporary and small-scale solution. You can go one step further to preventing limescale by treating the hard water before it enters the taps, which can eradicate limescale altogether! This can be achieved in two ways – water softening and, more recently, water conditioning.

Water softening swaps the calcium for sodium, eliminating the possibility of limescale. With a choice of electric or non-electric water softening, it offers a constant supply of soft water direct from the tap.

Water conditioning is a relatively new method, which doesn’t alter the chemical composition of the hard water but inhibits the way limescale adheres to surfaces. This is done through magnetics altering limescale crystals or electrolytic, which suppresses the limescale formation by adding traces of zinc or iron to the water.
