Agree with Fred. Test with the RSR 2000. This could even reduce the the rust somewhat.
Once confirmed, honing first helps to open the stone by increasing the surface area. Then poultice with Iron Out or similar product. Refinish as required after.
Removing rust can be difficult and not always at a 100% success rate.
Manage the results with the client.

Hello Partners!

We have a few marble floors within a clients home that have a very bright
orange/ pinkish staining. Has anyone ever seen anything like this or had
any success in removing them? Let us know, we greatly appreciate it!
