Brand new kettle, very hard water area: how do I stop the limescale build up?

Is there anything preventative I can do? Thank you!

Not sure about any other preventative except installing filters. Which costs. But it may be wirth it if it's really hard water because your appliances like washing machine etc will last longer.

For easy removal, boil water with lots of vinegar. Works like magic.

RedHeadedSnippet · 03/04/2025 09:45

I do think we need a filter, it’s awful. But that’s another rabbit hole!

Vinegar. Every couple of weeks I fill it 1/3 with white vinegar and top up with water, boil, leave as long as you can, do two clean water boils. It really is like magic. Almost makes me fear eating vinegar but I still do.

I buy 5lt bottles off Amazon or eBay.

Get a Brita filter and make sure you only fill your kettle with pre filtered water.

AnotherHappyCamper · 03/04/2025 09:51

You don't even need to boil.

Before you go to bed, put in 10/1 water to vinegar, or maybe 10/2 - you might have to experiment with how strong it needs to be - up to the level where timescale is present (so if you have a glass kettle, for example, you'll probably see a distinct line of residue).

Leave overnight, and in the morning your kettle will be pristine again.

I second the boiling of vinegar , but it really smells , I only use a small amount of neat cheap vinegar and either boil the kettle in the garage or near an open window , then rinse several times with clean cold water to clear out the bits

RedHeadedSnippet · 03/04/2025 09:54

I will try this! Just normal white vinegar? Doesn’t it taste a bit vinegary next day?

AnotherHappyCamper · 03/04/2025 09:55

Sigh. Brain not braining today. Might be a slightly different ratio - can't remember if I actually just did a litre in total with a good big slosh of vinegar...that probably makes more sense.

AnotherHappyCamper · 03/04/2025 09:55

Rinse out a few times in the morning.

AnotherHappyCamper · 03/04/2025 10:01

If you don't boil it you don't get the strong vinegar smell. Yes. Just straight white vinegar, bog standard, but make sure it's food grade.

SydneyCarton · 03/04/2025 10:05

I used to have some of these which worked pretty well. You just leave them in the kettle and the limescale collects on them and not the element. Just wash them off every couple of weeks and put back in.

Cheap solution: only ever fill with filtered water from a Brita water jug and regularly descale with citric acid.

Intermediate: install a water filter tap on your kitchen sink

Best solution: install a water softening system and water filter tap. You won’t know how you lived without it, it makes cleaning a doddle and your skin and hair are so much nicer.

MoonlightMemories · 03/04/2025 10:10

I live in a very hard water area and use a Brita Filter water jug with the Limescale Pro filters (they work much better then their regular ones in my opinion). I do still need to descale the kettle once a month or so though, but it gets nowhere near as bad as it did before.

I hate the smell of vinegar, so I use food grade citric acid granules instead, you can get them on Amazon in large amounts. Boil the kettle with water about 3/4's full, then pop a couple of tablespoons of the citric acid in, give it a stir, let it soak for a couple of hours, then empty into the sink, rinse the kettle out, boil and rinse once more with water and you're good to go, no more scum on the top of your tea/coffee!

HolyMacaroniBatman · 03/04/2025 10:18

A Brita filter won’t do anything; the calcium is dissolved in the water.

A water softener won’t help; you should be using a separate tap for drinking water that comes off the mains.

Regular descaling with vinegar as recommended is probably your best bet.

chemteacher · 03/04/2025 10:25

Half and half solution of previous posters, boil the kettle but flick the switch off before it comes to the boil, to avoid stinky vinegar steam. Then leave it sitting in the kettle for half an hour then rinse. Cold works fine too but takes longer.

Pigeonqueen · 03/04/2025 10:43

I live in a really hard water area and none of our water things last at all - ie shower, kettle, dishwasher etc. We all moan about it on the community Facebook page and everyone admits they just buy the cheapest of everything and replace more often. Not very eco friendly I know.

AnotherHappyCamper · 03/04/2025 10:54

Omg I'm hopeless! A bit more awake now, heh. That coffee really matters!

I realised I was conflating 2 or maybe even 3 methods including one of the store-bought mixes (waste of money!).

Best method I've used was just straight white vinegar up to the level needed, which was quite low in our kettle, then left overnight. 50/50 would also work, I think.

I prefer non-boiling but if you want it done quickly that's the way to go.

I used Power BI to set up a simple visual

MinkyWales · 03/04/2025 17:56

I stopped using vinegar. Citric acid is much more effective, and doesn't smell.

Bluevelvetsofa · 03/04/2025 17:57

A water filter has the initial expense obviously, but you will use less laundry powder or liquid, less soap in general and you’ll need fewer products. Much easier to clean bathrooms, appliances etc.

ItsMutinyontheBunty · 03/04/2025 18:00

Another back up from the cheapest options of using a water filter and cleaning out with white vinegar. I just soak for a few hours, rinse and then do one boil with water afterwards that I chuck.

GasPanic · 03/04/2025 18:17

Use bottled water. Or just chuck the kettle away and buy a new one when it gets really scaled up as they are cheap as chips. I think mine cost £12.

SwanOfThoseThings · 03/04/2025 18:25

Find a kettle buddy - someone who lives in a soft water area - and swap kettles every six months.

That's how long it took my limed up kettle to become sparkling clean when I moved from a hard to a soft water area 😄

MrsMoastyToasty · 03/04/2025 19:00

Never re-boil any water left over in the kettle from the last time you boiled it. Calcium carbonate (limescale) precipitates out of solution at 60°c. So each time you reboil it you're encouraging it to form.

uncomfortablydumb60 · 03/04/2025 19:02

I have extremely hard water. I put a mesh doughnut thing inside the kettle then descale regularly with 50/50 vinegar boiled then left overnight
