Is there anything I can do about it? We have a dark grey polished granite floor in the kitchen. It was installed by the chap we bought the house from - there is nothing wrong wth it, I just don't like that shiny thing going on on the floor. Have dogs etc and just want a good stone floor that won't show the dirt etc. Someone has told me you can get the top shiny layer sanded off? Has any one seen how it looks after this has been done?
