Texas...yeah, in Texan speak, that’s “a ways”.

I don’t think the more expensive meter is going to be of more value to you. I think you’d be wasting money if you bought it.

Call up the manufacturer and ask what is most effective on stripping your sealer. Stu may know outright. If I clean a tile install that has a sealer with a high alkaline cleaner, I usually assume I’m degrading the sealer. But I don’t know the percent of degradation.

If it were me, I’d strip the floor sealer and see if the staining stopped getting worse. Then I’d consider leaving it be or possibly replacing a few tiles (if I was certain it was a traditionally built shower without a layer of surface waterproofing).
