I have a bluish-gray "ring" that develops in my toilet bowls, more evident towards the upper area of the water level.

It really doesn't come off. It feels like a stain within the porcelain, as there is no crust, etc. Vinegar or bleach have no effect. I tried scrubbing the ring with Fast Orange with pumice, and it did notably remove some of bluing, but not all.

There is no blue coloring used in the water, which comes from a well, through a softener I got from Speedbump (Fleck and Clack, Resintech beads, rock salt), but I think this was starting before I added the softener.

Photo shows it with the water level down before I started cleaning it.

Any ideas??

Thanks,

You may have scrubbed through the glaze with all those abrasive cleaners...

Actually, there wasn't much scrubbing involved. I used a small paintbrush, going back and forth. I am a lazy guy, and wanted to see if they worked chemically, since the stain seemed to be in the porcelain, not to be felt by scraping with a fingernail.

Copper can show up as blue or green.

Hmm, interesting as I replaced the old rusty iron piping this summer with copper. Any ideas on how to remove the "residue"?

I googled it, lots of ideas, not sure you want to kill yourself for a toilet. I would think 6 month would be awlful fast.??
