I hope someone can please help me. I just recently bought a house and
the toilet, although clean is stained brown everywhere there is water.
There is a medium-dark brown underwater. All above the water is white
as normal. Scrubbing is of no use. I haven't tried any cleaners yet.
Can someone enlighten me on how this kind of stain could have
developed and how to easily remove it?
City water or well water? Water softener?
Rust removing cleansers like ZUD may help.
(Or you can get Oxalic acid and make your own.)
In the event cleaning isn't successful, spring for a new toilet;
they are not expensive and new ones only use 1.6 Gal/flush.
Iron-oxide . . . calle RUST by most people
Oxalic acid (powder), full strength. Turn off water to tank, flush
until no water remains. Sprinkle on power (should be at least damp),
then scrub, repeat.
But it will probably reappear fairly quickly because the ceramic's glaze
has worn off and what remains is porous.
Solution: buy a new toilet. The new glaze will resist rust for some
years. And install a water softener.

Rather than water softener that should be water conditioning equipment
as needed after an independent water test. There are a lot of water
conditioning scams around, many with well known names. Problems are
different in different areas.
If you don't get an "independent" water test, you really don't know what
problems you may have. By independent I mean someone who will not be
providing any equipment.
In some cases a softener may be able to handle a small amount of iron,
but more serious cases are likely to need specific iron equipment.
At the marine we lived at, the water came from a well, and left rust stains in
the bowls as well as shower stalls. We used about a 1/4 cup of oxalic acid in a
gallon of hot water, in a garden sprayer. Spray it on, wait a few minutes, and
rinse off. Spotless.
Oxalic acid (wood bleach) in the hardware store is about $6/pound.
I found it at a pool supply store for $55/50 pounds.
Resistant stains are more likely permanganates than iron oxides. Oxalic
acid is the right chemical to use if so. You can get small quantities in
spray cans of "Bartenders' Friend", "Stainless Steel Cleaner", and a few
other products. Also, try some dishwasher detergent, full strength for
about an hour. Pour a bucket of water down the toilet first so the siphon
action will empty the bowl.
