Dear Melissa:
In my experience, the best product to clean a shower stall from soap film and mineral deposit accumulation is MB-3.
However, before you rush and buy some, what must be said is that some times what appear to be hard-water mineral deposits could be something else; namely the indication of some serious structural problem due to the presence of water behind and under the stone tiles.
Before we go any further with this I would recommend that you send me a couple of pictures of your alleged mineral deposits.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
