How do I get ride of hard water stains on Uba Tuba and Dakota Mahogany?

 

Dear Craig:

Remove the worst of the mineral deposit build up (you do have a mineral deposit build-up, right? Or else how could they possibly be “hard water stains”?...) and then finish the job with a heavy duty alkaline cleaner with chelates in its formula and rated “for natural stone”, like MB-3.

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

Ciao and good luck,
