Using a grill cover is a great way to keep your grill clean and free of things like water spots, dust, dirt, pollen, tree sap, and unwanted presents from birds.
If you live in an area where it snows, it also makes it easy to just pull off the cover and get right down to grilling, instead of having to clean all of the snow off of the grill by hand.
If your grill is located in a humid area, you may want to periodically remove the cover to let the grill breathe for a little while if you go long periods of time without using the grill.
