Limescale: the hidden household annoyance

Limescale is a common problem for many homeowners, yet many do not know where it comes from or how to effectively remove it. In this article, we'll discuss everything you should know about limescale — read on to find out more.

What is Limescale?

What is limescale?
Limescale is the build-up of a hard white substance on pipes, taps, kettles, washing machines and other areas and appliances that regularly come into contact with water. It is mainly made up of calcium carbonate.

How is limescale formed?
Limescale is caused by hard water. This type of water contains magnesium and calcium ions, as a result of coming into contact with rocks during the water capturing and purification process. 60% of UK homes have hard water and in general, it has a minimum impact on the way we live.

However, when hard water evaporates, it leaves behind calcium carbonate deposits — or limescale as it is more commonly known.

What does limescale do?
Generally, limescale is relatively harmless, offering limited effects to our physical health. However, limescale build-up can be detrimental to the efficiency of appliances. For example, when allowed to build-up in boilers, it can cause heating bills to skyrocket and result in hefty repair bills by damaging vital internal equipment like the boiler pump.

In addition, it can be particularly unsightly on visible surfaces, ruining the sleek, polished finish of our interiors.

How to clean away limescale
Because limescale is effectively a sediment, it can be tempting to simply scrape it away. However, doing so can damage the surface it's on, ruining the appearance of taps, tiles and exposed pipes.

A better way to remove limescale is by using lemon juice or a strong vinegar. Because both of these are very acidic, they're perfect for cleaning away the residue.

As a preventative measure, technology has been developed by Combimate to help prevent scale building up. The easy-to-install device contains Combiphos, a natural material that prevents limescale from forming.
