Maintenance for granite is virtually non-existent. It can be routinely cleaned with mild soap and water, or you can purchase inexpensive granite countertop cleaners from your grocery store. Your granite is sealed before cutting even begins and this protects your stone from staining. You should re-seal every three to five years as needed. Oil spills can be problematic so, if you spill oil on your counters, clean it up as you go and do not allow it to sit on the stone for any length of time.
