Dear Lorena:
To remove soap scum from any surface you need an alkaline cleaner with chelates in its formula, and to clean the same soap scum from a natural stone surface you need an alkaline cleaner with chelates in its formula that's rated “for natural stone”, like MB-3. It doesn't really matter if the surface of the stone is polished or dull: a cleaning product inside a bottle is not smart enough to know the difference!...

It will just do its job of removing the soap scum without effecting the stone, period.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
