if the white marble tabletop already has stains, can I use this now?

I can't answer that question with impunity, but I can tell you that I have used this product on granite and marble and it has been impervious to stains of any kind for 5 years, and fluids still bead on it. It is the best stone sealer that I have found. Saying that, it is understandable that there are no stains at all on the countertop and floor that were new when I sealed them. I might scrub stained marble with CLR , rinse well, and allow it to dry a couple of days to to be rid of some soaked in stain. I have never had to deal with marble that had penetrated stains, so I can't be certain that my suggestion is a good one. Without a professional to assist in the suggestion, you might be taking a chance using something previously untried on a white highly porous stone. Personally, I would never want marble in a kitchen, because of fruit, wine/juices, grease, and dark sauce stains. Good luck,

Can I use this product to seal grout as well?

Hi JoyYesIt's a super grout sealant as wellRegardsWilliam

How long should I expect the solvent odor to linger in the room if I were to use it on the kitchen countertops (and turn on an exhaust fan or two)?

about an hour. We opened hte back door and used exhaust fans in the bathroom
