How to clean Travertine shower walls, especially grout.

I avoid using chemically aggressive materials like vinegar, breach. But, at grout lines, particularly where the travertine walls contact the fiberglass tray/floor, mold is difficult to remove.

You would need to find the source and repair - which could mean tearing down the whole shower. Water behind the surface could come from use or it can come from condensation on the back side of the shower due to lack of proper insulation in the wall.

Forfatter9 år sidenMy mold problem is not considered extensive, but it does need to be addressed by means other than elbow grease and commercial cleaning materials that likely would damage the stone.
Thanks to each of you for your input. I plan to remove and replace the mold on the caulk where the tile meets the PVC shower base and use a bleach/water mixture with a stiff grout brush on the grout where there is some mold. I do use DuPont StoneTech Professional Soap Scum Remover for Natural Stone on my shower Travertine tile. It does not appear to harm the stone or its sealer.- PRO

Any restoration professional knows that you cannot resolve a mold issue by cleaning alone. You must dry out the area causing the mold. Depending on the extent of the problem would depend on how you would dry it. If it's mold by caulk as you said and not grout it's not just surface mold (as opposed to if grout gets some mold (which is not as common) or the tile surface then sometimes it's just surface mold and bleach will remove it without any other measures necessary) I do not promote bleaching grout as a cleanser because it will ruin it over time (and it is not a good grout cleaner anyway) but on a rare occasion to remove some mold from grout, it will generally not ruin it as long as it is rinsed well afterward.

I have a ceramic tile shower pan that I use 409 on. When I had my tile floors power cleaned by a professional, he also did the shower which did a great job of cleaning, although we had to redo the caulk afterwards.
