Most household cleaning products people keep under their sink or in their laundry rooms include acid, which as already mentioned, will leave stains behind (exactly what you're trying to get rid of). The best marble-friendly cleaning products are phosphate-free solutions or even liquid dishwashing soap. The best way to use any cleaning product on your marble tile is to rinse off the soap instantly with warm water to keep from drying out the marble.Step 3: Removing StainsStained marble tile leaves you with two options: live with the stain or live with etched marble tile where the stain used to be. Many cleaners that remove stains from your marble countertop do so by removing the stain but also damaging the surface finish.'For food and oil stains, a better option would be to spread dry con starch over the stain, letting it sit undisturbed for 24 hours. The corn starch will absorb the oil from the stain on the marble countertop, and will hopefully prevent you from having to use the harsher, damaging, cleaners.'Removing rust stains is much more damaging to your marble tile countertops, as rust can only be removed by using specialized rust-removal products that only work by etching away polished surfaces.

A better option is to use a stone sealer designed specifically for protecting marble tile and helping it to resist the oils and dirt you just spent so much time and energy removing.
