Hello,
A white Porcelin sink we have always seems to develop a hard stain/coating on it that is a Bluish-Greenish color.
Any idea what minerals in water might be causing ?
And, what might be effective in removing it ? The typical, common, household cleaners have essentially no effet. Think Chlorox might work ?
Or,...?
Much thanks, Bob
Blue green might be copper. Removal? Not sure.

Bluish-Greenish color stain is most likely from copper pipes.
You probably have low ph (acidic) water or a small electric current in your pipes.
You should find the source of your problem and fix it before your copper pipes get slowly eaten away.
To remove stain, this page says use "Soap suds and ammonia, then rinse"
Copper reacting with sulkphur in the water? Copper ions are blue-green.
If that doesn't work, then maybe a product like CLR? It makes rust disappear quickly, would probably work on other metal based stains.
