I've got the same problem. Did not want to treat water but did add a
sediment filter which helps. Wife uses the acidic bowl cleaner every
now and then.
I was glad I did not add a treatment unit as hardness defined by amount
of calcium was only maybe a ppm too high. Close enough for me.
Neighbor with treatment discovered that you are not allowed to let the
salt flush of resin go to septic and had to pay to put in a separate
system for that.
My water tastes fine and that is all I drink and we cook with it but
wife does not like looks of sediment on standing and will buy bottled
water although she will use tap water ice cubes.
I've seen a well like that at friends hunting camp where water smelled.
As long as bacteria is absent it should be OK to drink. Mine has no
funny taste but, as I wrote, wife buys bottled water to drink as she
does not like to see sediment on standing. Several neighbors have water
delivered which I do not understand.
Our well is about 125 feet deep with a recharge rate of 15 gal/min.
Water has been much clearer last several months lately maybe because of
a lot of rain and wife is not cleaning bowls often.

That "rust" is more likely Iron Bacteria and is very pervasive. We have
learned to live with underwear (Bleach not kind to a Septic tank) that
is no longer white and stains in the dishwasher. We occasionally use
Rust-Out but is tedious to use and expensive.
For the toilet we got a thing called "Kaboom" dumbest name ever. It uses
large white Chlorine tablets and hangs in the tank ABOVE the water level
so it does not affect the water in the toilet tank. I had tried some of
the in-tank things and they ate the rubber seals.
Anyway, the kaboom tablets are expensive so I got some Brominator
tablets for cleaning swimming pools. About 30 x 1" diameter tablets for
Honey has not had to clean the toilet bowls for two years. Awesome
I have nothing to do with Kaboom or the bromine tablets, just a very
For stains already n the bowl, use Rust-Out and make a loose-paste
(pancake batter) and brush it on. It has to "work" for about 20-minutes
so you need to go back every five minutes and brush some more on as it
dries out and stops working. A royal pain, but once the stain is gone
the tablets will keep it that way.
Oren my huckleberry friend,
You forgot about brown cooties already?
You taught me all about them!
I suspect what the OP "thinks" is rust, is the brown cooties you described
in my sister's toilet bowl.
Remember I tried a dozen chemicals from phosphoric acid to pool acid?
I tried bleach. I tried vinegar. I tried Ajax. I tried every powder in the
Nothing works as well as plain old pool acid.
Gone in an instant.
To the OP. Run a search for my name in
Put a couple of keywords about the toilet bowl cleaning and you'll find the
I have given a half-dozen neighbors jars of pool acid since, and they all
cleaned their toilet bowls of what we can nicely term "rust" but which
isn't rust in the least (as proven by the fact that the rust removers did
nothing and the bleach bleached them white).
To the OP:
What you have most likely is some kind of mineral deposit (depending on
your water, mine was calcium carbonates) with poo poo on top.
It's probably not rust because if it were rust, the phosphoric acid would
Oren kindly explained to me what it really was:
I documented the use of all the chemicals that people suggested:
Go to tinyurl.com/alt-home-repair and search for:
Experiment removing brown toilet bowl stains with various acids
You'll find this thread where I documented every household chemical:
Here is the final experiment in progress:
And here is the penultimate picture, with only a little more to go:
Here are composite photos from that thread:
So, your *first* revelation is to realize that it's not rust.
Ask Oren for the details.
