When I moved in about 2 years ago, the bowl below the water line was
badly stained a brown colour. Thinking it was the obvious, I
eventually took the plunge to see if it would be easy to remove. It
simply wiped off and I had a perfectly white bowl.
However, the bowl is again starting to stain. It is flushed after
every use and the water is clear, there is no staining in the cistern.
Using a toilet brush would prevent anything building up over time, but
what would be causing it?
The water may look perfectly clear, but I can assure you it ain't. With
water standing in the bowl for any length of time, the small particles do
settle out against the porcelain. Try taking a white cup and filling it
with water from your tap, then let it stand on the window sill till it dries
out. You'll be amazed at what you find after all the water is gone.
the whole lot into the bowl and use a long handled washing up brush to get
it up to the rim. You may need to do this on and off for a couple of hours.
If you can be bothered to temporarily block the WC with a towel or
something, you can just leave it overnight.
IME this treatment lasts for a good couple of years. Once you get rid of the
salts, the colour can't build up so easily.

I was recently in a supermarket in spain and for some reason found
myself in the household chemicals aisle. (What a great way to spend
part of your holiday).
I spied some stuff which appeared to be some sort of descaler and
eventually managed to work out that it was hydrochloric acid. Every
supermarket seems to have it (always right next to the household
ammonia - another chemical now rather uncommon in the UK).
Nice that you can still buy dangerous chemicals within the EU!
I would like to put HCl into my kettle and toilet from time to time.
(Actually I remember when I was young you could buy it here under the
name "spirit of salt").
I'm planning to get some brick acid and pour it into my toilet. What
concentration would you recommend?
I've already tried emptying the trap and leaving it 24 hours with 2 litres
neat bleach filling the U-bend. It made it much cleaner, but there's still
loads of scale and general nastiness.
Doesn't need to be strong -- the scale dissolves easily with no
effort, just give it time. I use around a spoonful of Furnox
descaller (DS-3? -- large tubs available from B&Q or plumbers
merchant) dissolved in a pint of warm water and then poured
into the u-trap and left for an hour or overnight. You could
add a few drops of washing up liquid too if it's really bad,
but that's not necessary unless it looks really bad. (Don't add any
other cleaners as you might end up releasing clouds of chlorine
gas.) After leaving to soak, one wipe with the toilet brush and
flush, and brilliantly cleen loo, much more effectively and for
far less cost than any of the proprietry loo cleaners.
Bleach doesn't really clean anything like this, it just makes
the dirt invisible (for a short length of time).
Full strength, and leave it, slap the toilet lid down and put your
extractor in fill blast, or open a window. It will degrade rubber and
plastic seals and pipes so don't leave it more than overnoght, then
follow up with bleach to neutralise, wait, and do it again if necessary.
Neat bleach? Use neat caustic soda crystals :-) Turns turds into soap
and silt that does!

I'm not certain how concentrated it is and have not used it for a
toilet application. Since you probably don't want something too
vicious I would have thought diluting 5:1 would be a good start.
Add acid to water, of course, and you definitely do not want any
bleach around because copious amounts of chlorine gas would be
released. You can always increase the concentration of acid if
Just remember ANY cement joints in the drains will be eroded by the
acid, do it too often and trouble awaits, the water companies don't like
it either, not only due to drain damage, but it kills the microbes in
the sewerage farms...
Niel, with a rather large acid treatment plant at work!
You still can, in decent builders merchants and hardware shoppes. Used
as brick cleaner.
GFor bogs tho its a tad drastic. Most of teh proprietary descalers work
well, and then one of those loobloo things chucked in teh cistern
ocasionally works well too.
Or fitr a water softener. That stops it forming in the first place.
Bad enscalation can be chipped out, complete with its brown stains...not
a nice job.
