Dear Debbie:
First off, a soap film remover is not designed to clean mildew stain. For that you'd need a mildew stain remover rated for natural stone like MB-9.
That said, I'm a little concerned (actually, a lot) about your report of the fact that just a couple of week after cleaning you have a heavy build-up of “soap scum” and mildew. There's no plausible reason for that: soap film accumulation occurs over a few months, not a couple of weeks. Ad so does mildew.
However, if you have a structural issue – and here is where my concern is – the problem is not poor housekeeping, but something different and, alas, more serious; and it is certainly not by trying to solve the perceived problem that you'd be able to solve the real one.
Take a look at your grout and/or caulk lines; is there any grout missing and or cracked? Or did the installer feel like being “Italian” that day and installed your marble tiles butt-joint? If this is the
If the tiles were set butt-joint (close to one another with no provision for a grout gap), then the only solution is, alas, a jack-hammer. If instead there's room for grout but it came off in some places, let me know and, depending how serious the situation is, I will tell you what to do.
Like I said before, I sincerely hope that my diagnosis is wrong, but the way your report is worded is somehow alarming and I wanted to anticipate a different possibility.
May I ask you now to please read and e-sign our Statement of Purpose at:
