Dear Rebecca:
You don't need to necessarily feel a film to have the visual effect of mineral deposits. Around the faucets I would recommend to remove the worst with a razor blade (no, it will not scratch the stone!), and then finish the job with MB-3.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
