cleaning travertine

[awally]

I have travertine (not sure where it originated) in a small back bath on the countertop. I seal it every six months with the 511 product. On one of the tiles there are a few spots and a ring where a glass apparently sat. Is there a prouct I could clean this with? It may have been sealed in at some point and I may need to strip that sealer. Any product suggestions?

Thank you-

Hi awally, Welcome!

This ring is a etch caused by something acidic coming in contact with the stone. There are no impregnating sealers to protect against this type of damage. No need to remove the sealer. If the stone isn't damaged too badly, the etch may be able to be just polished out.

Is this travertine polished (shiney), or honed (mute sheen at angle)?
