Best limescale remover 2023: Protect your surfaces, pipes and appliances from damage

Is your home plagued by unsightly white stains on bathroom taps? Sounds like limescale. The easiest, and often cheapest, method of kicking it to the curb is to use the very best limescale remover for the job.

Any white or copper-coloured markings near home-based water sources are likely to be limescale, particularly if you live in a hard-water region. As we’re sure you know, these stains just don't seem to budge when using ordinary cleaning products. Limescale leaves an unsightly finish to otherwise clean rooms and appliances, which can even develop into serious plumbing problems down the road, so it's best to deal with any outbreaks promptly.

Fortunately, descaling products – or limescale remover – can fight this problem head-on. Below, we’ve compiled a list of the very best options for whether you’re cleaning your toilet, dishwasher or pipes. Before that, though, any first-time limescale-busters or readers looking to learn more about this pesky substance should read our guide to what exactly limescale is and why it occurs.

To best understand how to get rid of limescale, it's good to know what it actually is.

Limescale is essentially a build-up of calcium and magnesium called calcium carbonate and usually deposits as a white, chalky substance.

Build-up is likely anywhere in your house where water is present, such as boilers and radiators, but particularly in areas where water often lingers before evaporating later on, like tap ends or showerheads. It can deposit quickly, too. In fact, the average family of four generates around 70kg of limescale in just one year, so it's best to keep an eye on the limescale-prone areas of your home.

Limescale problems are worse in parts of the country where hard water is found. Hard water contains high concentrations of mineral ions, usually magnesium and calcium. These chemicals are perfectly safe for you – in fact, bottled mineral water is often packed with the stuff – but it is only heavily concentrated in water from certain regions of the UK since it needs to pass through ground rock like chalk and limestone. These rocks are filled with the "hard" minerals and so the water picks them up along the way. When water evaporates, these hard minerals are left behind on surfaces and slowly build up to become visible matter like crusty layers caked on your shower head.

It should be noted that even soft water areas can get limescale; it might just remain invisible to the eye for longer, so a descaling session is always worth doing if you suspect there to be a problem.

The regions with the hardest water tend to be in the East and South of England; however, parts of the Midlands, the North East and Scotland are also affected. Check out the water hardness in your area here.

Don't fret if your kettle contains any chalky matter as limescale won't cause you any health scares. However, it can create problems for your home. Left to fester, limescale could block water flows in boilers, radiators, taps and beyond, making them much less efficient and therefore increasing energy bills as you look to make up for the shortfall.

According to British Water, just a 1.6mm coating of limescale on a heating element can decrease efficiency by 12% and cost you at least £200 extra in energy bills per year. In the most serious cases, prolonged limescale damage could even crack your pipes or cause your boiler and radiators to stop working, so it's best to deal with the problem before it gets serious and costs you too much money.

Unfortunately, unless you up sticks and move house, you’re stuck with the water your region provides. This means limescale will always be a problem, though limescale removers make it an easy fix.

The most common descalers are acid-based bottled liquids, but there are also powder sachets (often used for dishwashers, kettles or the inside of other appliances) and sprays made for easier application. Whatever form of descaler you pick will tend to have safe acidity levels for any surface, although it's always worth checking the label since some materials such as chrome can be damaged by higher concentrations of acid. More natural alternatives also exist, though they may be less potent.

For a higher price, there are also electronic descalers, which are usually used for piping so as to avoid the hassle of deconstructing or replacing the pipes themselves. Meanwhile, an even larger lump sum can get you a more permanent fix in the form of a water softener. These devices reduce the hardness of water as it comes into your home to prevent any limescale degradation from the off but often cost between £300 and £1,000.

All you need to do is spray the gel on the sides and under the rim of the toilet bowl, leave it to work its magic for around 20 to 30 minutes, and then clean the toilet bowl with a toilet brush, although many users note that just a good soak will remove limescale without any need to brush.
