How best to clean my granite flooring?

[GraemeC]

Hi all and thaks for reading!
I have granite tiles on my bathroom floor, they were probably laid in the 50's, the are a greenish colour and have a matt type finish to them. Over the years they obviously havent been cleaned that well. I would like to revive these tiles as i am sure they would be expensive to replace.
can anyone advise me on haow best to restore them and what type of cleaning product will work best?

thanks in advance

Granite floors have to be treated carefully, and you shouldn't use ordinary household cleaners on them.
Damp-mop your floors regularly, and put good mats down so that the residue from peoples socks/footwear doesn't harm the granite and cause a build up. The old-fashioned type of mops are best to use, and you can add products such as you'll find in the link. Then polish with a product that's specially designed for granite and marble flooring.
