Wait Until Spring to Clean your Grill
Now that summer is over, you may be thinking about putting your barbecue into storage. If you usually clean your grill before storing it, you may want to consider leaving the baked-on crust in place until next spring. The reason? To keep your grill from rusting.
Go ahead and wipe down your grill before storing your barbecue. When you take it out again next spring, give it a deep cleaning by applying heat from an open flame for about 10 minutes. You should then be able to scrub the crust off without too much effort.
