Dirt/Grime on waterline Travertine tiles

[patrickguinn]

Hi All,

Does anyone have a good method of removing dirt/grime/oil build up along the waterline tiles of a light-colored travertine? I've tried baking soda and a scrub brush, but that doesn't seem to touch it.
Maybe hit it lightly with a pressure washer?

Thanks,
Patrick

Do you have a picture of the grime/buildup and do you have your latest water test results to share? Helping identify the source will help the recommendations going forward.

Sure, thanks for your help. Attached pic of wall with dirt/grime (also - if you've experienced mold spots, like shown in the pic...how to get rid of them?). Pic of latest water test attached too.

Any ideas?

I would try a Magic Eraser as that cleans just about everything in my house!

I think the magic eraser could work. I've also seen people post good success using the scum sponge type products in the skimmer to absorb any surface oils like sunscreen etc. Tennis balls in the skimmer can also do the same thing.

Lastly, your chlorine is way too low regardless of the "Ideal level" column. For a Stabilizer/CYA of 60, your target range is 7-9. See the link in my signature for the full FC to CYA chart.
