Moving to a house with what I believe are granite or marble counters, and I have seen conflicting info on how to keep them clean. What's the bottom line? A wet sponge alone? Sponge with a little dish detergent? Just the sponge daily and then something else to really clean on a periodic basis? And is it different for granite or marble?
Also, will a glass with ice water leave a stain on the counter? Do you put pots right off the hot stove onto the stone?
