Can Tilex be used for a pool tiles?

Hi there, and thanks for asking. Our Clorox Plus Tilex ProResults Mold & Mildew Remover doesn't have any claims on whether or not it can be used for pool tiles. It isn't safe for natural marble; however, it is safe for synthetic marble. It's also safe for most bathroom surfaces, including grout, tile, tubs, fiberglass, glass shower doors, vinyl curtains, counters, sinks, and no-wax floors. If you're unsure, you may spot test it on a small inconspicuous area before using it on the whole surface. We hope this helps. If you have more questions, give us a call at 800-227-1860 and reference this number: 210316-000725. Have a great day. Jeffery from The Clorox Team
