Toilet Limescale

[Smowball]

We have very hard water and even though our bathroom suite is only a couple of years old we have really bad limescale at the very back of the toilet, from the rim right down to the actual water in the bowl -one vertical very bad line of limescale. Everyone keeps telling me to use Coca Cola, but it’s not in the bowl. I need to put something on it that will cling to it and remove it. Any ideas??

Various limescale removers are available - I use Harpic. Marvellous.

Agree with Harpic, I use the power plus x 10, also in a very hard water area. Never got a build up of limescale since using it.

This one....contains hydrochloric acid, the best for dissolving calcium carbonate deposits, bar none. Thick too.

Only last weekend I had to unblock a toilet and remove years of thick limescale deposits. I only ever use one product as it shifts any scale almost instantly. It is very powerful and you cant be in the room once it is applied, it is far too pungent . Having used it for years on end I can asure you it will tarnish chrome, so can only be used on porcelain. Gauntlets, goggles and a mask are a must and follow the instructions.

^^^spirits of salt is, of course, hydrochloric acid....as per my suggestion, above.

Ive tried Harpic. Hasn’t worked. X

Have you tried vinegar?
I know it doesn't 'cling', but it should start fizzing the limescale, and then you can repeat the process.

If hard water problems really do bother you then subject to your attitude and budget etc - longer term, you might want consider installing a water softener. No doubt you will benefit from other AB ers opinions on such a course of action?

[woofgang]

smow, harpic will work but you have to persevere....two or three times a day for as long as it takes.....But yes a water softener is the answer, I love mine.

Another water softener addict here. No scale anywhere and tap washers, toilet flushers etc last for ever.

I live in a very hard water area and limescale is a nightmare. I use Domestos zero scale, in the black bottle. Try to leave it on as long as possible, but comes off a treat.

I used to get this. Once I got the limescale off I started to use in-cistern toilet blocks (you don’t have to have blue ones, they do clear!) and now I never get limescale anymore. And the loo is always clean!

[tonyav]

Pumice powder, mix it with a bit of water to make a paste and then get scrubbing.

[choux]

I think you have the answer there, meglet. Don't let the limescale build up in the first instance.

[DTCwordfan]

I endorse Harpic Bleach (a white pack - largely so).

[woofgang]

bleach doesn't remove limescale...chemically it can't happen.

Was about to say bleach wont remove limescale .. it will only whiten it, it may appear to have been removed after bleach treatment, but it hasn't. It wil still be there.

I tried all the remedies when I had the same problem, a while back.
None of them seemed to do much good, so in desperation, I fashioned a piece of wood (softwood) in the shape of a chisel and used it to scrape some pretty big flakes off.
The wood was hard enough to bust the scale but not so hard to damage the glaze.

You want some sort of paste or gel that will stick to where it's applied https://www.lakeland.co.uk/21274/Gel-Kilrock-Limescale-Remover-Descaler-160ml
