Greg, sounds like you just have an unreasonable customer. I did
a lot of research a while ago because of all the chloride staining in Hawaii,
the dark spots on granite that are locked in, it is insoluable salts, and
I learned the water is loaded with nitrates and chlorides and they will leave a
deposit on or in the stone, not to mention the silica which comes from being on
a volcanic rock. Seems like impregnating can exasperate this problem, as the
water beads up it makes the mineral rings more apparent. what about
some of your nano glass treatments, they are more of a surface type sealer
although I know the chemistry is more for igneous material… Or a
wax of some kind.

Subject: [sccpartners] Marble Shower
I have a customer in Maui that is complaining about water
stains on the floor of her highly polished marble shower. They have a water
softener installed, and the company that installed it, tested the water and
says that the water is fine. We polished out the mineral buildup and sealed the
stone and grout with Limestone & Mable Protector and after about a weeks
use, they have heavy duty water deposits on the floor again. They seem to think
that we are not using a good impregnator because the spots should be easier to
clean off. I explained to them that impregnators keep the stains on the surface
but will not do anything about the minerals in the water that are being left
behind.
They claim that they have the same marble shower in their home in California,
without a water softener and do not have this problem.
Is there a way to prevent the minerals from bonding so well to the polished
marble floor? Do you know of a product that will remove these deposits with out
harming the polished finish?
Thanks
