Clean the cook box. Remove the cooking grates and use a stainless steel cook brush to brush all the excess grease and debris from inside of the grill into the collecting bottom tray. Then, remove the bottom tray and throw out the collected grease and debris.[15] Some of the debris will be loose and easily disposable, whereas other debris will be caked on. You might need to use a scouring pad or a sharp putty knife to remove the stuck on debris.
Brush your grill grates after every use (inspect for wire brush bristles before cooking), and thoroughly clean them every couple of months, depending on grill usage. And twice a year, you should give your grill a thorough cleaning, which helps it cook better and last longer. The basic process is the same for gas or charcoal grills; charcoal grills just have fewer parts.
Cast iron grill grates conduct heat quickly and evenly, cooking and searing meat for that distinctive charbroiled flavor. But to achieve those delicious results, cast iron grill grates need proper seasoning and regular care. Seasoning cast iron grill grates when they're new keeps your food from sticking and can prevent rust to make the grates last longer. Cooking on cast iron helps to create a smooth, non-stick surface to minimize seasoning needs in the future. Cast iron is porous, and as meat cooks, fats and oils soak into the pores where they harden.

Re-assemble all the parts you removed, taking care to fix the burner tubes back in place in proper position with the cotter pins or screws. Rub cast-iron grill grates with a light coating of vegetable oil. Finally, re-connect your propane tank and fire up the grill; let it heat for at least 15 minutes, then turn it off again. This will help burn off any residues from cleaning, season cast-iron grill grates, and serve as a check that you re-assembled everything properly.
No matter what you are grilling, you should always begin with clean grill grates. Not only does this make it easier to flip and remove the food from the grill but it also does not impart any flavors from previous grilled meals, such as barbecued chicken, into the steaks. Make sure to clean your cooking grate using a stiff wire brush. It is best to do this after you've finished grilling while the grates are still warm, but you can also clean the grill while it is preheating if you discover caked on residue. Taking the time to brush off old bits of cooked-on food will pay off handsomely when your steaks release from the cooking grate with ease.

Check the fuel lines for invisible openings. Create a mixture of soap and water. Make sure you stir the mixture around so it gets really sudsy. Then, use a paintbrush to brush the soapy mixture onto the fuel lines.[6] Turn on the gas, and brush some more soapy water onto the gas lines. If any bubbles form on the gas lines, that indicates a gas leak. Immediately replace any fuel lines that exhibit signs of a gas leak.
