I've been getting this discoloration at the bottom of my toilet. It
looks like something is peeling off the bottom, but not sure what it
is? Anyone know? Also, is there a chemical product that i can use to
get rid of this? Pic below. Thanks.
Calcium buildup from the water supply (hardness).
Muriatic acid is very effective in dissolving
Muriatic acid is also VERY dangerous to use!!
Wear eye protection and have good ventilation.
Rubber gloves to protect skin.
Plunge the bowl to get rid of as much water as you can.
GOOGLE "muriatic acid" so you know what you're dealing with.

I would try diluted muratic acid (follow directions) to clean it and
rinse well. My guess is your water causes this.

Calcium buildup. If it is a light case a product like clr might remove it.
For a heavy layer reduce the water level to the lowest point and use about a
quart of muriatic acid with the window open. The fumes are nasty.
Be very careful if you use the acid!!!!!!!!!!!!!!!
It's also excellent for removing calcium deposits from the
porcelain on sinks (around the faucets and drain). A few
drops of white vinegar every few months does wonders for
Not sure it will handle heavy deposits in a toilet bowl tho'.
Could try let the vinegar working for a few hours, scrub with
a stiff brush, and repeat. I guess one would get there in the
end but it might take a few days.

Stronger, I think, than vinegar but safer, I think, than muriatic acid
would be Zep Acidic Toilet Bowl Cleaner sold at Lowes. They sell a lot
of Zep products in their cleaning and janitorial section. It has
hypochloric acid, which sounds similar to muriatic (hydrochloric) but
is probably weaker and whose warnings are less. And it's already
diluted. And it's also a bit thick so it clings to the sides better
than muriatic acid would (which I have somewhere and have used a
little bit.) Blue with yellow lable on white plastic bottle.
It can take several applications with soaking and brushiing inbetween
to completely clean the bowl.
There used to be anohter brand, with a largely green or 3-color one of
which is green bottle, and the tub cleaner by that company is still
sold around Baltimore, but I never see the toilet bowl cleaner. (Not
talking about CLR)
Vinegar is amazing with mineral build-up, but you have to let it soak
for quite a while - several hours to a couple days. What I would
recommend is if you are going away for a weekend or otherwise traveling
for a few days, turn the water supply off on the toilet, flush it until
you have little-to-no water left in the bowl, pour in a few cups of
vinegar, close the bathroom door and leave.
When you come home, use the toilet bowl brush to dislodge any stubborn
bits of mineral, turn on the water and flush. You should get rid of
most, if not all, of the mineral build-up. If there's anything left,
try one of the milder cleansers such as Bon Ami...I would stay away
from the chemical cleansers at first, just because I'm not sure how
they'd react with the vinegar (which is basically acetic acid) and what
fumes might be created. After a couple flushes you might be OK to use
the chemical cleaners.
I did this recently with my shower head, which had a TERRIBLE calcium
build-up, and the vinegar worked like a dream.
hows it flushing? the build up often clogs the inner bowl passages
causing poor flushing.....
muriatic acids risks are overstated, just have window open, dont
splash, wear gloves. wear eye protection in case you splash by
i just take a deep breathe hold it use acid and leave room immediately
years ago acids were used all the time without the safety hype
Hardwater deposits. How often do you use a toilet
cleaning solution? and scrub the dark area shown.
Contrary to others, you probably don't need any
special acid, regular toilet clean products
usually are acidic. What you should try and
probably the quickest and best approach is using a
pumice block ("PUMI" or some such name). Turn
the water supply off, flush the toilet, put on
your rubber gloves and scrub. Probably take 1
minute to remove most of it and will probably
smooth the surface enough to retard future deposits.
