There is much debate as to which type of grill cooks better: Charcoal or gas. But one thing they have in common is how easy they are to clean. To maintain a gas or a charcoal grill all you need is a rag, a wire brush and some cooking oil.
Routine brushing of the grates prevents food and bacterial buildup. A brass wire brush is best for clearing and cleaning off surfaces. After each use, wash and soak your brush in hot soapy water. Then hang dry it with the brush upside down on a grill hanger. Drying the brush naturally ensures the bristles will last a long time. After your brush is dry, keep it indoors to reduce weather exposure to the bristles.
After you've brushed down your grill and the grates are at a cool temperature, spray it down with some cooking oil. This prevents your grill from rusting and ensures a long life. If you don't have cooking spray, another option is to pour some oil on your rag and wipe down the cast iron grates.
Cleaning the burners is also important as burners can accumulate grease and food, leading to uneven temperatures along your surface. After the burners have cooled, scrub with a wire brush evenly and clean around the ports to ensure food and grease have not amassed.
Cleaning out grease traps is important because grease is highly flammable and can cause a fire or heat up all surfaces, including the handles.
For charcoal grills, it's important to dump all used charcoal or ash after each use. After dumping out the remains, clean the insides with a wire brush. Ash catchers also need to be cleaned. By keeping the bed of your grill clean, you'll cut down on excess smoke and bad flavors.
Several times throughout the year, it's smart to dismantle your grill and give it an extensive cleaning. If you have a gas grill, disconnect the propane tank before beginning the process. Then, soak the grates in soapy water and scrub. If the racks are especially dirty, you can use a steel wool pad. After cleaning your grill, turn it on and let it cook for 10 minutes. This will allow any residual cleaning supplies to burn off.
It's also a good idea to check the chassis for rust. Rust easily comes off with a stiff wire brush or a steel wool pad. The joints, connectors and fasteners should also be inspected to ensure they aren't corroding. And re-tightening fasteners, replacing grill appendages (wheels, knobs and handles) and checking hinges is a good idea.
Polishing Your Grill
To polish your grill, sprinkle some baking soda on a sponge and clean off all exterior surfaces. Aluminum foil gently rubbed along your grill can help remove grime and buildup. If you notice any missing paint, grill-safe paint is a good option.
