After about 30 minutes, turn the heat off and let the grill cool down. Wipe things down to remove any lingering residue and you should be good to go. The grill grates should have turned a bronze or dark brown color if they are metal or a darker brown/black color if they are cast iron. For cast iron grates, the oil will have penetrated the pores of the metal and created a smooth non-stick surface that will be perfect to cook on.
Clean out the burners and venturi tubes. The venturi tubes are the pipes that go out from the burners and connect to the grill control valves. These tubes allow the air and gas to mix together, altering the intensity of the flame. Remove the burners and venturi tubes, and place a hose head at one end of the tube. Turn the water on to clear out any debris or insects that could have gotten inside.
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. 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.
Chefs and the cooks who know their way around a kitchen (or a grill) know how meat feels when it's raw and when it's cooked. The only way to learn this is to basically poke the steaks at different stages of cooking. Raw meat is almost squishy, rare meat is quite soft, medium rare meat resists your poking a bit, and medium meat springs back. Once meat feels firm, it's at least well done, if not completely overdone. Gently press a finger onto your steaks—being careful not to burn yourself—to teach yourself the difference.
Outdoor grilling is a great way to get together with family and friends and enjoy tasty food. However, the outdoor fun is only possible with a grill that is cleaned and maintained throughout the year. There are a few simple cleaning steps that you can do after every time you grill, along with deeper, semi-annual cleaning steps to keep your grill working its best for years to come. An outdoor grill that is kept clean and maintained will stay in good working order and will ensure that the food you cook on it always tastes great.
