How to Remove Bleach-Based Discolorations on Travertine

Q. The travertine in my shower was cleaned with a bleach-based cleaning product, causing a stain. Will my travertine need to be replaced?

A. Bleach should not cause a stain on travertine. You are probably seeing alkaline etch damage. A stain happens when a colored substance is absorbed into the stone. Poultices can be applied to draw out stains. Etch damage is a chemical reaction on the surface of the stone that damages the stone. Poultices will have no effect on etch damage. This is not a DIY project. Please contact your stone restoration contractor to hone and polishing the travertine to blend with the surrounding finish.
