Sounds like you wore through the sealer - might be able to clean off with Dawn dish washing detergent (undiluted, rub with rag then rinse well), or with a cultured stone polish available at most box and home improvement stores - be sure to get the non-abrasive type, not the abrasive buffing type. Then you would need to put on sealer.

Professionally - some Countertop and Stone dealers provide this service, as do many Ceramic Tile and Bathtub Refinishing vendors. If you wore through one spot, likely time to clean and reseal the entire thing. Usually kits include a cleaning solution, buffing/polishing pad, and sealer; or same vendors will do it as a service.

If this is a deeply ingrained stain, rather than just surficial soap scum and such, may require surface grinding, followed by polishing, buffing, and sealing. Again, same vendors, but likely in the couple to few hundred $ range rather than the $50-100 range for spot cleaning or $100-200 range for cleaning and resealing the whole tub.

Another common solution if in bottom - clean and reseal to prevent stain from spreading through the area, then cover with a stick-on non-slip decal.
