Hi, We recently installed black granite in our kitchen. We noticed two lighter strips at the front of the sink. I have tried acetone to remove the white strips, but it appear to make it only wider. The strangest part is the "hole" cutout for the sink does not have these marks on it at all.
I am thinking of using a poutice (baby powder + acatone) or using methylne chloride, but I am concerned about making it worse than better.
I would appreciate any input anyone can give us.
