Marble Wax Seal

Four no wax polishes.
Marble wax seal. Remove the wax. Marble wax is used as a coating to protect the surface of the marble. I recommend dupont stonetech bulletproof sealer. This will remove any impurities from the surface of the marble that may interfere with the sealing process.
It will usually only take a few minutes. At a minimum wait at least 10 minutes for the wax to soak in. To do this use grade 0000 steel wool. The best marble sealer is going have low or no vocs volatile organic compounds and be environmentally friendly.
As you are carefully removing the wax you will need to make sure you are not getting wax back onto the countertop. Spread the sealer across the entire marble countertop with a clean dry cloth and let the sealer soak into the marble for the length of time specified on the product s container typically less. This sealant is a protective layer between the stone and the outside world. This will make your stone yellow.
Lastly remove the wax from your countertop. Since marble countertops grace many kitchens the sealer will also be certified safe for use where food is prepared. There are specific marble polishes easily found. Stay away from wax and polish.
What should you use as a sealant. It needs to have a solid manufacturer backed product warranty. This means it is nsf ansi 51 2012 compliant.
