Remove Limescale from Your Kettle?

Limescale in the kettle builds up because of hard water. If you’re not sure what kind you have, try a quick hard water check or use a test strip at home. So, when is it time to clean or soften your water?

How to Descale a Kettle: Step-by-Step Guide

If your kettle is slow, noisy, or your tea tastes bad, it might be time for a clean. That white chalky stuff you see inside your kettle is limescale. It builds up fast, especially if you live in a hard water area. The good news? You don’t need to be a scientist to know how to descale a kettle. You can clean it using things you already have at home, and it only takes 10-15 minutes.

How to Clean a Kettle With Vinegar and Baking Soda

Here’s a simple method that works well without using any strong chemicals:

    • Step 1: Fill the kettle with water until it’s about three-quarters full. Then, add an equal amount of white vinegar (a natural limescale remover) or, if you prefer, instead of vinegar, toss in a few sliced lemons for a pleasant scent.

    • Step 2: Boil it – One boil does the trick with vinegar. With lemon, go for three.

    • Step 3: Cool and rinse – After it’s boiled, let it cool down. Pour it out. Rinse with fresh water a few times.

    • Step 4: One last boil – Fill it with clean water and boil again to get rid of any smell or aftertaste.

    • Step 5: Clean the outside – Grab a damp cloth, a little antibacterial spray, and give the outside a quick wipe. You’re done!

Some people use baking soda with water instead of lemon. It works in the same way and helps remove buildup too.

Commercial Descaling Products

If you don’t like the smell of vinegar or want something stronger, there are shop-bought kettle descalers. The best kettle descalers are made to break down limescale quickly and work well if you follow the instructions. The downside? They cost more over time and may leave a strange taste if you don’t rinse your kettle properly.

You still need to boil the kettle and rinse it well after using a descaler. Always read the label before you start.

Safety Tips When Descaling

Cleaning your kettle is simple, but still, here are some descaling solutions for your kettle to keep in mind:

    • Let it cool – Don’t open the kettle or pour out boiling water right after it boils. Let it cool a bit first.

    • Unplug before cleaning – Always unplug an electric kettle before wiping or rinsing it.

    • Don’t touch hot surfaces – The metal parts can get really hot, so give them time to cool.

    • Keep it away from kids – If you’re using vinegar or boiling the kettle, it’s safer to keep children away while you clean.

What Does Limescale Look Like

Limescale is the white, chalky residue that accumulates in kettles or coffee machines, particularly visible on stainless steel. This is a common problem in hard water areas, where there is a higher concentration of magnesium and calcium. 

Removing it needn’t be a huge chore, though it does need to be done frequently to keep your kettle in top condition. Try using helpful tips, like the ones mentioned above, on how to clean limescale from your kettle and prevent it from building up.

Do you need a water softener?

Test the mineral content in your home’s tap water.

If it’s 100ppm or above, you have hard water. A water softener can help you avoid limescale buildup, saving time and money.

* PPM stands for parts per million and indicates the concentration of dissolved limescale minerals like calcium and magnesium in water.

When to Descale Your Kettle

You can take good care of your kettle, but it still needs to be cleaned sometimes. Maybe the water looks a bit cloudy, or your tea just doesn’t taste right. If it starts making weird noises too, takes much longer to heat up your water, there’s a good chance limescale is building up inside. You might even spot white flakes in your drink or see a crusty layer inside. When that happens, it’s probably time to descale your kettle.

Is limescale bad for health?

Limescale comes from the high concentration of calcium found in the hard water we drink, so it will not cause you harm if you consume some from your kettle or coffee maker.

Kidney stones occur when there is a build-up of a substance in the body, such as calcium, ammonia, or cystine. However, there is no research which shows that drinking hard water increases your risk of developing kidney stones. In fact, you’re more likely to develop them if you’re not drinking enough water, so it’s worth keeping your kettle in top condition and brewing up!
