Just remembered something that I wanted to pass along. I have been having problems with my granite counter tops. Whatever I cleaned it with, left a cloudy film. And then one day I just used 3 little squirts and cleaned the entire surface... yes out counter is about 12 feet long. No problem at all. It seemed that I was using way too much. So, if this has been happening to you, try a little bit less each time and see if you get back that sparkle.
And, the brand I was using was one of those environmental brands. Can't think of the name, but it smells just like gin and bitter lemon lol!!
