I have a sandstone rock shower and need a product that will remove soap film and mineral deposits. Wil the MB-3 work on this and not affect the rock?

 

Dear Brian:

Indeed, MB-3 wuilol work well on your stall and be safe on your sandstone. Just make sure that what you have is actual soap film and mineral deposits, and not some sort of efflorescence as a consequence of water having found its way behind and under your stone. That would be a totally different proposition that would require a totally different approach.

May I ask you now to please read and e-sign our Statement of Purpose at: http://www.marblecleaning.org/purpose.htm?

Ciao and good luck,
