I north London here the water is quite hard (i.e. a lot of chalk in it), so
we easily get limescale
build up in the bend of the wc bowl.

Using Harpic Limescale Remover has shifted most of it, but that seems to
have left the porcelain area under water a kind of a dirty colour. I then
used a lot more Harpic, but nothing has improved. Although it does seem to
come off a bit with lots of hard brushing. Anyone any idea if this Harpic
could be causing this?

Limescale remover doesn't work under water.
Empty the water out the pan then use the limescale remover again

Scale is composed of many chemicals and the harpic simply removed the
easily dissolved ones leaving a harder one behing. You removed it with
hard brushing.

Acid, including vinegar, dissolve lime. Bleach could be used to
remove iron stains.

Harpic used to advertised it's toilet cleaner (post 1940s) under the
heading "Clean around the bend".

Unfortunately that expression was also used to describe (slangily)
someone with a mental problem! Politically incorrect perhaps!

So instead of saying, as we might today "He/she is nuts" or "Like
crazy, man" the Harpic expression was sometimes used as a nickname!

PS. What's that other cleaner advertised on TV as a rust, lime,scale
remover? Something like RLS or RSL ??????

Terry,

CLR is a common cleaner in the US for this.

thanks to all. i've never seen CLR here in the u.k. would anyone
translate what it is, and would it be good for my application? Other wise
i see myself getting the water out of the bend (any tips on the best way to
do this other than spooning it up?) and using the harpic limescale remover.

I have used muriatic acid,

first plunge toilet, then sponge remaining water out of bend.

then pour most of acid down overflow tube in tank. this cleans the
interior toilet passages espically around the bowl rim. do you have
brown deposits around rim that clogs the holes and causes poor
flushes?

pour remaing acid in bend area wait say 15 minutes and flush noramally
say 10 times to dilute and move along any remaining acid.

use normal safety precautions open bathroom window. wear safety
glasses, pour acid into water NEVER water into acid, wear rubber
gloves avoid splashing, and take deep breathe, apply acid, get out of
room and close door promptly.

wait the time which gives acid time to work.

this is espically effective for toilets where the water swirls but
solids dont go down well.

Not long ago I fixed a friends toilet that had been broke over 2 years
in 15 minutes.

the acid dissolves the hard water sediment

The scale is a mixture of limescale and organic matter which
has embedded itself in it. They require quite different chemicals
to shift them. In the UK, buy a descent scale remover. Sulphamic
acid is the most common scale remover, and you can buy a large
tub of it at a builders/plumbers merchant under the name Furnox
DS-3. This will work out about 100th of the price of all those
kettle descalers you buy which are diluted with sand and other
rubbish. (Sulphamic acid isn't the best choice for descaling
plastic parts, as it can make them go brittle.) Empty the U-trap
by oscilating the water back and forth with a toilet brush.
Dissolve some DS-3 in warm water, and refill the U-trap with it.
A few drops of washing up liquid as a wetting agent might help.
Leave it to do the work for as long as you can. Brushing will
not much help beyond the occasional stir, although at the end,
it might break away undissolved material. Flush away.

If you've still got any dirt left, this will be organic. For
this, repeat the task above using washing machine detergent
(Europe only) or dishwasher detergent (Europe or US). This
will benefit from some light brushwork, and this will also
clean up the toilet brush nicely. Dishwasher detergent can
give you alkali burns, so be careful not to splash it around.

When switching between chemicals, make sure the previous
chemical is completely flushed from the pan and pipework to
avoid any danger of a reaction giving off fumes. Don't use
bleach -- it doesn't clean anything and just makes dirt go
temporarily transparent so you can't see something is still
dirty. It can also react very badly with many other cleaning
agents.

Get a mop (old type) or a big towel and pump it in the bowel until all
the water is out or soaked into the towel/mop. Dry bowel with tissue.
Apply limescale remover. Wait. Wash off and check results.

Harpic (or other brands) will help keep your pan clear of limescale
if applied regularly but it doesn't work too well under water to
remove existing scale.

Use a pumice stone.

It works and alot cheaper than the chemicals. :-)

Have you tried cola? Sounds daft but I pushed out most of the water
with the loo brush and filled with cola. Did it when I went to work,
flushed when I came home...and voila...a clean loo bowl. Have used
white vinegar in the past as well, works well.

Thanks for all suggestions. With regard to the pumice stone idea, surely
that would take the gloss of the glaze?

Limescale aka calcium carbonate (CaCO3) aka Rolaids.

Use hydrochloric acid (HCl) to dissolve it into calcium chloride (aka
road salt).

You'd think so, but no it really doesn't. You can always to a test patch if
you're not a believer :-)
