Granite Countertop Sealing. Saturate the surface with the product. Since most types of natural stone are porous, the material is susceptible to damage from liquid and stains that can penetrate the surface.
Get a good-quality granite countertop cleaner, a granite sealer that's designed to resist water and oil-based stains, and some clean rags. Although these materials appear to be maintenance free, in fact all of them are porous and must be sealed in order to be protected against staining and dirt build-up. Follow the cleaner's directions first, making sure the granite is dry before you start sealing.
This can cause unwanted problems and should not be done "just to be safe." Find Granite countertop cleaners & sealers at Lowe's today.

This used to be the advice from stone professionals over the years. If you cook frequently in your kitchen and use the countertops daily, you might need to reseal the granite even more frequently. A good granite countertop sealer not only seals the pores but also cleanses the surface.
