That chalky white buildup on taps and showerheads is limescale, and if you live in a hard water area, it is one of the most common cleaning jobs in the home. The good news is that a simple, cheap acid soak clears most limescale without any harsh chemicals.
How Do You Remove Limescale From Taps and Showerheads?
To remove limescale, soak a cloth in white vinegar or lemon juice, wrap it around the affected area, leave it for at least an hour, then scrub gently with a soft brush and rinse clean. The acid in vinegar or lemon juice breaks down the calcium deposits that make up limescale, so soaking time matters more than scrubbing pressure.
What Causes Limescale?
Limescale, chemically known as calcium carbonate, forms when hard water containing calcium and magnesium evaporates and leaves mineral deposits behind. It is not harmful to health, and water in hard water areas remains perfectly safe to drink, but limescale can reduce water pressure and shorten the working life of taps and showerheads over time if left to build up.
What You Will Need
- White vinegar or fresh lemon juice
- A cloth or paper towel
- An elastic band, string, or a plastic bag
- A soft brush, such as an old toothbrush, for tight corners
- A clean cloth for drying
How to Remove Limescale From Taps: Step by Step
1. Soak a Cloth in Vinegar or Lemon Juice
Soak a cloth or paper towel thoroughly in white vinegar or fresh lemon juice, making sure it is fully saturated rather than just damp.
2. Wrap It Around the Tap
Wrap the soaked cloth snugly around the affected area, covering as much of the limescale as possible, and secure it in place with an elastic band or string so it stays in contact with the surface.
3. Leave It to Work
Leave the cloth in place for at least an hour. For heavier, older buildup, leaving it for several hours or overnight allows the acid to work more thoroughly through thicker deposits.
4. Scrub Gently
Remove the cloth and scrub the softened limescale with a soft brush or sponge. An old toothbrush works well for tight corners and awkward fittings that a cloth cannot reach easily.
5. Rinse and Dry
Rinse the tap thoroughly with water to remove any remaining vinegar or lemon juice residue, then dry it with a clean cloth. Drying is an important final step, since leaving the surface wet allows new limescale to start forming again almost immediately.
Removing Limescale From a Showerhead
For a removable showerhead, unscrew it and soak the whole head in a bowl of white vinegar for at least an hour, then use an old toothbrush to clear any remaining deposits from the individual spray holes before rinsing thoroughly. For a fixed showerhead that cannot be removed, fill a plastic bag with vinegar and secure it around the showerhead with an elastic band, following the same soak-and-scrub approach used for taps.
A Word of Caution on Finishes
Vinegar and lemon juice are safe on standard chrome fittings, but matt black, gold, and brushed brass finishes can be damaged by prolonged acid exposure. For these finishes, warm soapy water is the safer everyday choice, and if you do try a diluted vinegar solution on stubborn limescale, always test it on a small, hidden area first.

How to Prevent Limescale Building Up
- Wipe taps dry after use: a quick dry with a cloth prevents water evaporating and leaving mineral deposits behind.
- Clean regularly: a light wipe-down every week or two stops limescale building into a thicker, harder-to-remove layer.
- Consider a water softener: if you are in a hard water area, a water softener reduces the calcium and magnesium in your supply, cutting limescale buildup throughout the home, not just on visible taps.
Frequently Asked Questions
Does vinegar or lemon juice work better on limescale?
Both are effective mild acids that dissolve limescale in a similar way. Lemon juice can act as a mild bleaching agent in sunlight, so vinegar is generally the more neutral, all-purpose choice.
How long should I leave vinegar on limescale?
At least one hour for typical buildup, and up to overnight for older, more stubborn deposits. The longer soak time allows the acid to work further into thicker limescale layers.
Is it safe to use vinegar on all tap finishes?
No. Standard chrome fittings handle vinegar well, but matt black, gold, and brushed brass finishes can be damaged by prolonged acid exposure, so warm soapy water is the safer everyday option for these.
Why does limescale keep coming back after I clean it?
In hard water areas, mineral deposits reform as soon as water evaporates on a surface. Drying taps after use and cleaning regularly slows this down, though a water softener is the most effective long-term solution.
Can limescale damage my taps permanently?
Left untreated for a long time, heavy limescale buildup can reduce water flow and, in some cases, contribute to internal wear on tap mechanisms, so removing it periodically helps protect the fitting’s working life.
Always test any cleaning solution on a small, hidden area first, particularly on coloured or coated tap finishes, before applying it more broadly.
