I bought a 100+ year old house. It has a Claw Foot tub, which I will
retain. Unfortunatley it has a a few Rust stains, from the drain
chain, near the drain etc.

I have tried many items, to remove those rust stains - Ajax, Gel
Gloss, Soft Scrub.

Can anyone recommend a way, that I can remove the rust stains?
CLR or Phosphoric acid come to mind.
