How to stop limescale in your home
Limescale is a hard, chalky deposit left behind when hard water evaporates. It is common across much of the UK. Here is how to keep it in check.
Where limescale builds up
Look at taps, shower heads, toilet cisterns, bowls and anywhere water sits and dries.
Toilets
A white or brown ring in the bowl and scale in the cistern are classic signs.
Cisterns
A cistern descaler block is placed in the tank and works every time the toilet flushes.
Check
Never place a cistern block in the bowl, and follow the pack instructions.
Taps and showers
Chalky white crust and reduced flow often point to scale in the aerator or shower head.
Filtered shower heads
Some shower heads include a filter stage that is designed to reduce deposits.
Tip
Wipe taps dry after use to slow the build-up.
A simple routine
Little and often is easier than a big descale.
Weekly
Squeegee shower screens and wipe taps dry.
Monthly
Clean the toilet bowl and check the cistern.
Safety
Never mix cleaning products and keep them away from children and pets.
Frequently asked questions
Is limescale harmful?
It is not harmful to touch but it makes surfaces look dull and can reduce flow in taps and shower heads.
How often should I descale?
It depends on how hard your water is. A quick monthly check works for most homes.
Can I mix cleaning products?
No. Never mix cleaning products, because some combinations release harmful fumes.
