How to remove stained limescale in toilet

[Leaveitonthefloordrobe]

I got some great advice from this board about getting rid of bathroom mould so I though I'd ask here again!

Some members of my family have a terrible habit of leaving urine to linger in the toilet unflushed. We're in a very hard water area so a lot of limescale and the limescale in the family toilet is now badly stained. I've scrubbed and scrubbed but to no avail. Does anyone know of any miracle treatment to get rid of the staining below the water line?

Apparently scrubbing it off with a 2p piece works. Not tried it yet!

Use the brush to get rid of as much water as possible

Tip white vinegar down the loo (will probably need a whole bottle) and leave it overnight

Have you tried Viakal? You may need a few goes, and you may need to reduce the water level in the toilet pan first.

Black harpic

Kilrock

Large volumes of bleach

Full fat coke. Empty the water out by pushing a loo brush down the toilet vigorously a few times. Then pour a couple of bottle of full fat coke down it. You may never drink coke again.

Second vote for coke. Bail out as much water as you can from the bowl. Fill up with full fat coke so it covers the limescale - leave over night. Scrub with a pan scrubber and flush.

False teeth cleaning tablets. Leave two in overnight.

Black harpic is the shit for this. Bleach won't do it as you need to dissolve the limescale so you need acid based products.

Coke (phosphoric acid) and vinegar (acetic acid) ought to work depending on the location of the limescale, but I my go to is the black harpic cos the nice sticky stuff lingers on all the hard to reach places.

Citric acid crystals. You can buy a kilo on Amazon for a couple of quid. Dump a load in the toilet bowl. You can also use citric acid to descale kettles and get rid of limescale around taps.

This works for me.
You might have to do it a twice if it’s really bad.

White vinegar left overnight here too
The black bottle Harpic cleaner also works if it's on offer!

We had this when we moved into a new house. Vile. Tried bleach and coke etc but nothing touched it.

In the end I had to don a rubber glove, stuck my hand in and scrape it off with an old knife. It took numerous goes and flushes before it went.

Spirit of salts and you will have a sparkling loo by morning.

Bar Keepers Friend is fantastic for this!

Scrape off the excess first with an old knife and then just throw a load of BKF down the pan and leave for an hour or two.

When my dd moved into her apartment, the wc was in a terrible state. I did the above and it came up like new. 👍

Kilroc

Denture tablets. Whole tube of them in the bowl and leave overnight

Once I shared a house with a builders daughter and her dad gave us some brick acid which did a sterling job too

Bleach tablets - Sainsbury's sell them.

Kilrock for sure. I tried everything, everything! (Even the stuff that promised me it would beat everything else.)

Put Kilrock down the loo; left it overnight; used a long screwdriver to loose all of the limescale from the loo, which fell away immediately. Flushed. Perfect!

Make a paste with ordinary vinegar and bicarbonate of soda. Cleans really well and it's a cheap solution.

Coke didn't work; Steradent didn't work; vinegar didn't work - btw.

Black garlic

Harpic!
