Limescale build-up in your bath and how to remove it

A bath with limescale built up inside

If you live in certain areas of the UK, then limescale forming in your bath can be an annoying problem that you may want to deal with.

In this article, we’ll look at what limescale is and some methods of getting rid of it from your bath.

What is limescale?

If you’ve ever seen a white, chalky deposit around your shower head, taps, plug holes or tiles, you’re probably looking at a buildup of limescale in your bathroom.

Limescale is caused when hot water evaporates and leaves deposits of calcium and magnesium behind.

This issue mainly affects homes in the south of England where the water supply has a high mineral content. This is also known as ‘hard water.’

A limescale buildup is not harmful to health but can look unsightly if not removed from your fixtures and fittings, like baths or taps.

However, it can be serious if allowed to formulate in your central heating pipes, narrowing your waterways and making your boiler and heat pump work harder and less efficiently.

Methods to remove limescale

There a a few methods to remove limescale and some things you can do to stop it formulating in the first place.

Vinegar and water

White vinegar is a fantastic way of cleaning all sorts of things and its ability to get rid of limescale is well known.

Dilute 1 part vinegar with 3 parts warm water and pour or spray it onto the area with the limescale.

After about 30mins, scrub it off with something like a dishwashing sponge. It needs to be firm enough to take off the limescale but not to abrasive so as to damage the finish of your bath tub. Then use a damp cloth to wipe any residue away.

Limescale remover spray

There are many brand name products specifically designed to deal with the problem of limescale.

These are normally in the form of a spray or gel and can be applied to the affected area before being scrubbed and wiped away.

Not quite as eco-friendly as white vinegar, but you might find a dedicated limescale remover useful for particularly large or stubborn deposits.

Water softeners

Water softeners are a useful bit of kit that you can often store out of sight under a sink, in a utility room or in the loft.

They contain large blocks of salt and are connected up to your plumbing system close to your mains.

All water coming into your home passes through the water softener and the calcium and magnesium is extracted before it reaches your taps.

This ensure that the previously hard water is ‘softened’ and will help to reduce or even completely prevent mineral deposits from building up in the first place.

If you live in a hard water area and have a luxury whirlpool bath installed, adding a water softener to your water supply will help to prolong the life and smooth running of your bath.
