Honed quartzite kitchen counter. Help
I just installed a quartzite tile countertop in my kitchen. I sealed using impregnator as instructed but have a problem. The first day I got a drop of vegetable oil on it and it will not come up. It is just a dark spot. I have tried everything. So, first question is what will clean it and second question is should I have oiled all the tiles (like you do with butcher block)?
