Do you keep your grills/smokers covered or uncovered? My friend believes that covers retain moisture and promote/accelerate rusting. I currently cover my grill, but I have found a cover with a mesh backing that I believe to help ventilate the grill when covered. I live in New York, so weather extremes are common. Snow does not sit on the grill for long since I use it all year long. Snow is removed from my deck even before my driveway. Thank you!
