Any suggestions on cleaning these stains. I tried vinegar and baking soda works ok but these are pretty deep.

Don't know what they're are from.

Try CLR but read instructions about what it can be used on.

Our porcelain gets a 23% acid recommended by a janitorial supply, but it ain't nuthin like that, only calcium build-up. Consider taking that picture to a janitor supply and asking their opinion.

Have you tried powedered cleaning powder like Comet, Ajax or any other brand? It might not come out in one go as those stains look pretty deep, but it should come out eventually.
