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.
To season the grill, rinse the grill grate with plain water, then dry it thoroughly. The next step is to apply a fat – either vegetable oil or shortening – to the grates, coating all of the cast iron with it. Place the grill grate over a cold grill, then slowly increase the temperature to about 400 degrees and keep it there for about 40 minutes. Finally, allow the grill grate to cool.
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.
If scrubbing isn’t your thing, there's Carbona’s 2-in-1 Oven Rack and Grill Cleaner. This kit contains a large zip-top bag and a 16 oz. bottle of cleaner. Simply place your grates in the bag, pour in the liquid, seal the bag and shake gently so the cleaner coats the racks. Let it sit (away from children and pets) eight hours, or even overnight. Afterward, remove the racks from the bag, lightly scrub away any stubborn residue and rinse them well. In our GH Institute Cleaning Lab tests, even grates from a charcoal smoker came out clean with virtually no effort, thanks to this product.
Brining or soaking the ears in water before grilling is thought to season and also plump the corn. There are two problems with those theories, though: In order to take on any salt from the brine, ears would have to soak for several days, at which point you’re losing valuable sweetness as the ears age. Secondly, if you’re buying fresh juicy corn, you cannot make it any juicier. While soaking may benefit older or off-season ears, it has no added value for fresh summer corn.
According to Taylor, you'll be able to find this tool in stores, and it's also sold online by Amazon. If you can't wait that long, then use a nylon brush, but make sure to do this only when the grill is cold. Another option is the $15 Sumpri Grill Brush and Scraper. It's made out of stainless steel and is bristle-free, too. While I haven't used it personally, it appears to be popular with Amazon shoppers.
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.
