Charcoal grill
Step1
Use a stiff wire brush to scrape away any loose debris from the grill and grates, then remove the grill and grates.
Step2
Scoop out any ash at the bottom of the barbecue with a large spoon or cup.
Step3
Clean the inside and outside of the barbecue with baking soda (or another abrasive cleaner) and a little water using a metal scouring pad. If your barbecue has a painted, a nonstick or an aluminum surface, use dishwashing liquid, water and a plastic scrubber (not abrasive cleaners and metal scrubbers).
Step4
Place the grill and grates in a large plastic bag and cover them thoroughly with oven cleaner. Allow them to sit for several hours or overnight. If the grill and grates are aluminum, soak them in dishwashing liquid and water instead.
Step5
Remove the grill and grates from the plastic bag and place them atop several layers of newspaper.
Step6
Use a metal scouring pad or stiff brush to scrub them clean. If the grill or grates are aluminum or nonstick, use a plastic scrubber, not a metal one.
Step7
Hose off the grill and grates to remove any remnants of the oven cleaner. Use the hose to clean out the barbecue itself as well.
Step8
Allow everything to dry thoroughly, then replace the grill and grates.
Step9
Coat the grill with vegetable oil to prevent rusting and future buildup.
Gas grill
Step1
Examine the flexible hose. If it is cracked or damaged, replace it with a new one.
Step2
Consult your owner's manual for basic maintenance tips (see also
How to Troubleshoot a Gas Grill). This will include checking the metal tubes under each burner. Spiders and other creepy crawlies like to nests in these tubes, which causes blockage and possibly even a fire. Use a paper clip or toothpick to clear these holes if necessary.
Step3
Remember that many gas grills are made of aluminum products, so you'll want to avoid abrasive cleaners, including oven cleaner, and metal brushes or scouring pads.
Step4
Soak the grill and any removable parts in dishwashing liquid and hot water. Scrub away buildup with a rag, sponge or plastic scrubber.
Step5
Remove the porcelain grills and flavorizer bars and run them through the dishwasher. Or scrub them with a brass wire brush.
Step6
Replace the lava rocks every year with new ones or boil them in soapy water to remove built-up grime.
Step7
Tape over any gas openings and then clean the inside of the barbecue with hot, soapy water and a rag, sponge or plastic scrubber.
Step8
Clean the outside of the barbecue with hot, soapy water and a rag or sponge.
Step9
Hose out the barbecue. Allow it to dry thoroughly before you replace all of the parts.
Step10
After everything is dry, rub the grill with vegetable oil and any wooden parts with linseed oil.
Step11
If you have a quick disconnect, make sure it is securely fastened before you use the grill.
