Rejuvenate Countertop Polish, 16 oz

Q: What product removes hard water stains from cultured marble?

Nothing gets a stain out of marble. You can have it re finished (sanded ) and re coated. Marble is porous and soft Rejuvenate is great to shine and clean but not to lift stains.

Q: Is this product safe to use on laminate kitchen countertops?

YES. According to the product's description, it is safe for use on laminate kitchen countertops.

Q: Can I use this cleaner for an E stone counter top ?

Don't know what Estone is, but I returned this cleaner. It is not worth the money, it did not 'rejuvenate' anything and is in my opinion worth then furniture dust spray. I don't think it is doing anything to hard surface.
