How to Remove Limescale

Last Updated: September 24, 2020 References

Limescale is a calcium carbonate deposit left when water evaporates from a surface. Over time, this mineral builds up, causing white crystals to form. Limescale often forms on household appliances as well as on surfaces like taps and shower heads. Luckily, using basic white vinegar and some elbow grease, you can easily remove limescale to reveal the sparkling surface underneath!

4
Run a water cycle. After you have done a vinegar cycle, do a regular cycle. For coffeemakers and kettles, fill with water and boil. For washing machines and dishwashers, put the machine through a cycle without any soap or cleaner. This will wash out any remnants of the vinegar to leave your appliance vinegar and limescale free!

If you are cleaning a coffeemaker or kettle you may want to do several cycles so you don't taste the vinegar the next time you use it.

Submerge the head of the faucet. Sometimes the head of the faucet needs special attention because it is the place that tends to accumulate the most limescale. If you notice that the rest of the tap looks great but the head still has some limescale, take a small cup of vinegar and submerge the head of the faucet in it.^{[12]

Question

How do I remove limescale from around my faucet taps?

Community Answer

Use acetic acid or white vinegar. For heavy build-up or extra stubborn limescale buildup soak a rag in the acid or vinegar and wrap it around the faucet taps. Let the soaked rag sit an hour or two around the taps and the limescale should come right off.
