@SunnyBeBe, others may have a differing opinion, but I have always heard that you should use special cleansers on natural stones like marble and granite. I specifically selected quartz for my surfaces so that I could spray the Lysol and other disinfecting and degreasing cleaners on it. I’ve had red wines splashes, mustard, tomato sauce, etc., and never had to worry about which cleaner I use. When we PTA members decided to give the school staff lounge a facelift, we decided on quartz because we knew that over the years, the cleaning crew isn’t going to “baby” the counter and backsplash like we would at home if we had chosen another surface. In fact, when we went to the stone place to look at slabs, the guy there told us not to go with granite or marble. There are now some porcelain tiles that mimic marble beautifully! And I’m not sure how much marble cleaners are compared to regular spray cleaners. Just my opinion! I’m sure there are others here who have marble or granite and love it.
