Q. How can one remove hard water deposits (probably from calcium) from granite (specifically Emerald Pearl)?

A. We suggest that you first try a soap film remover. It will remove not only film, but hard water deposits without damaging the polished surface of your stone shower stalls. If that doesn't do the trick, you may need to call in a restoration professional. If you don't already have a PRO, contact us.
