We remodeled our 1/2 bathroom about 4 years ago. I now have 2 boys (age 4 and 2)who love to play in the sink. I've noticed that around the hot water handle in an area about 4 inches across the granite is rough and is cloudy. I'm sure there's been standing water there, but I don't use abrasive things to clean the bathroom I've put on our granite sealer and do so as recommended, but I have not seen any improvement in this area. Can someone help?
