Toilet Bowl Stain


Hi to all!
I'm having an odd stain/growth issue in my own home!
In the of my toilet bowls, a grayish/brown growth is occurring.
It starts out at the front end of the bowl just at & below the water line.
It rapidly gets larger.
It forms at several points under the water in the bowl, at various points in the bowl.
If I clean it, it reforms in 2 days.
The 2nd floor bowl is a cheap bowl, I have changed all of the internals, and if left unchecked the bowl inside is a solid mass of grey. It first started in the that toilet and had been going on for about a year but its gotten pretty bad.
The 1st floor is a Toto. It just started to develop that same symptom about 2 months ago.
Internals have been changed in that bowl as well.
Nothing in either shower nor either sink.

The bowls have been in use for 15 years.
Piping is all copper with a small, canister style whole house water filter which , also, has been in use for 15 years.

I am baffled. Never seen anything like this.

Re: Toilet Bowl Stain


It looks like something is living in the guts of the flush, like everything below the flapper, down to the jet hole.

How about this? Drain the bowl, plug the jet hole, then pour a bleach solution down the flush valve hole. Some will pour out the rim holes (unless you block those, too). Let it sit for a while to kill what's in there.

Or just dump some bleach into the bowl every once in a while to see if it makes a difference,

Or get new toilets.

Re: Toilet Bowl Stain


I would have your water tested. I have a similar issue and it's due to the water quality. Not much I can do about it since I'm in a condo environment, but at least you'd know why.

Re: Toilet Bowl Stain


Looks like a water issue to me.

FWIW, the bowl rinse passages are almost never cleaned.

Re: Toilet Bowl Stain


Is that something growing or is it sediment? Do you have to scrub/scrape it off?

Re: Toilet Bowl Stain


It's definitely something growing....not sediment.
Without a new flush it multiplies rapidly....and a new flush will not remove any of it.
It has to be scrubbed off.
The 2 toilets have nothing in common except the water supply.
The odd thing is that it doesn't appear in any porcelein sinks.
Ive been in literally thousands of homes....as a GC and as an Inspector, and Ive never seen this.

Re: Toilet Bowl Stain


mold mildew or algae chlorine bleach kills 'em all.

Might be getting transferred by toilet scrub brush one fixture to next.

Might be in water lines - UGH.

I've seen this before, caused by over-consumption of habanaro burrito's.

Re: Toilet Bowl Stain


I have nothing to add about the source, but I have to be kind to my waste water since I'm on a septic system so harsh chemicals are out. We get calcium deposits here and I tried the pumice stone but notice they scratch the porcelain so I tried wet/dry sandpaper. Worked great and made short work of it. I hit it with 220 then 400.
