Dos and Don'ts?

Hi Maurizio,

I found your site with the Q&A's and find your answers to be very honest and straightforward. I was not able to find the Dos and Don'ts that are referred to in many of your answers. Would you please send me a link or an attachment?

Thank you. I'm especially interested in learning about marble and granite care and maintenance as I'm going have granite installed in the kitchen and bath and possibly marble in the master bath. 

Thanks again,

Elaine.
