toilet limescale removal

Obviously I mean turn the water content of the bowl acidic, not the bowl itself. Simon.

Brick/patio acid::Builders merchant.

But realistically you will alwyas need a similar amount of conc. acid to dissolve a given amount of scale.

What it boils down to is cost and collateral damage to e.g rubber seals

Brick acid? From your local builders' merchant or shed. Strong stuff, so handle with care. But your local water authority may not be too pleased to have acidic water flushed into their drains and sewage plants. It may attack any cement seals between sections of old clay pipes in the drainage system, if such there be these days. But how would they know it was you?

Alternatively, a bottle of vinegar, left overnight?

I'm surprised you have to actually empty the water from the toilet and U-bend every time. The directions on Domestos zero limescale don't mention that AFAICT.

How do you empty the bowl?

I find that by using the sort of toilet brush which has a large rubber disc behind the bristles, I can expel most of the water round the bend with a continuous pumping action. I then get the rest out with an old cooking baster (not the one which SWMBO currently uses!) - sucking it up and depositing it into a 2 lb marmalade jar.

Might it be easier all round to buy a water softener?

I suppose acid just in the bowl should not be touching any rubber seals in the pipes, and when flushed away, it will be diluted. Simon.

Wait until one of you relatives helps baste the turkey at Christmas. And remind me not to try any of your marmalade !

I have used a small cup to get rid of most, then a sponge to soak up the rest. And choose a non-windy day to reduce drain smells.

I guess the alternative would be a limescale reducing device somewhere in the supply. But I don't like that holiday showering in soft water thing where you can't rinse the soap off, so maybe just in the cistern feed.

Also sold as Spirits of Salts in proper hardware stores.

If you want to go natural, citric acid is likely a better bet.

Why bother emptying the bowl? Just bung the lime scale remover around the bowl, maybe slosh the water about a bit and leave it. either overnight or all day whilst at work. Good brushing and it'll be clear.

BTW check the ingredients on the limescale remover, they are not all created equal, even the "power" ones. A good strong one has around 9g of hydrochloric acid per 100 ml of liquid (Harpic Orginal Power Plus).

Because its always half an hour before someone important is coming round, so there's only 30 minutes to do the job ;-)

Fit a water softener.

Fernox DS-3 is sulphamic acid. The crystals are easy to handle, but about as acidic as you can get. I wouldn't want hydrochloric hanging round the house

Be very careful what you use. I have seen the glaze damaged by strong acids.

Use the Domestos more often & leave it longer. e.g. weekly & overnight.

Do it last thing at night.

Or in the morning if you're off to work. I sometimes use bealch and hot water, I've trined limescale remover for kettle and while it works well on kettles doesn;t do much in teh toilet.

Does not seem to work. The big problem is around the bend out of reach where it begins to pong a lot very soon after any cleaning of the bits you can get at. Acid can damage the glaze. Brian

This is what wet and dry vaccuum cleaners were invented for!

A 1kg tub of Fernox DS3 from a plumbers merchant... Chuck a table spoon in and stir it up, leave it for as long as you can. It won't attack the glaze or seals etc.
