Learning how to clean your gas grill is important. Whether it’s before or after grilling out or even preparing for winter, there are a few helpful tips and tricks that can make cleaning a grill easy and efficient. The Home Depot is your source for all of your grill cleaning needs. We have grill brushes, grill cleaners, grill cleaning pads, and so much more.
If the grates are really dirty, soak them a second time to help soften and remove more gunk without expending extra elbow grease. Or, try the new Sienna Grilltastic Grill Steam Cleaning System. Fill this electric scrubber with water, plug it in and in seconds the combination of the dishwasher-safe stainless steel brush head and hot steam will be blasting grease from your grates. (It cleaned our GH Test Kitchen grill so well, our recipe testers asked if they could keep it.) Finally, rinse the grates well and let them dry.
For metal and cast iron grill grates, coat lightly with a high temperature oil like Canola or Peanut oil – wipe off any excessive oil, install the grates and fire up the grill.  Heat the grill on high and let it burn for ~30 mins.  This will burn all the solvents and impurities off of the heating elements, grill grates, etc.  Note that porcelain grates won’t need a coat of oil, but will benefit from the burn in process to remove any chemicals/impurities that were applied by the manufacturer. 

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.
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.
Yes, you should touch the steaks to test for doneness, but that doesn't mean that you should be flipping and moving and poking a lot. Steaks should only be flipped once, and only moved once from a higher to a lower heat. And don't poke them with anything but your finger! Put the meat on a hot grill—they should sizzle immediately—and leave them there until they release on their own accord. If you're pulling or struggling with them, they are not seared and not ready to flip.
Now it’s time for propane flames to meet with forged cold steel. Turn up the heat and sit back while you watch the griddle plate blacken. The griddle will billow with smoke. That’s called “smoke point” and it takes about 30 minutes for your Blackstone to get there. So relax, grab a seat, and watch the smoke fly by. When all the smoke’s gone, you can turn off the griddle.
With the grates removed, brush down the inside to clear out any loose particles that have collected in the bottom and around the sides. Scrape off any large peeling flakes of carbon and grease and if yours is a charcoal grill, empty the ash catcher. Don’t forget to clean the drip pan and grease cup in warm soapy water and line them with aluminum foil so they’ll be easier to clean next time.

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.

After the grates and panels have soaked, take them out and scrub them thoroughly. A long handled grill brush offers added leverage. For really stubborn gunk, a paste of vinegar and baking soda helps the brush scrub off the worst bits. Rinse them clean. Take care to thoroughly dry cast-iron grates. Now’s a great time to inspect porcelain grates for chips that may lead to rust later on.
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.

While the grill grates and flavorizer bars are removed and soaking, tackle the caked-on gunk in the firebox. Put another bucket underneath the firebox where the grease tray sits to collect debris. The easiest way to start is with a wet/dry shop vacuum, whether full-size or a portable, like Milwaukee’s M18 hand vacuum. Since wet/dry vacs are mostly workshop items, you won’t feel bad about using one to suck up the gunk that’s collected in your grill. You can use the grill brush to help loosen stubborn stuck-on grit. If the deposits are really caked on, dip the wire brush in the bucket of soapy water and get to work. Use a hose to rinse it out when it’s clean.
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.

One school of thought suggests that applying the pepper before cooking can cause the pepper to burn while you cook it, imparting a bitter flavor. Followers of this school suggest grinding pepper onto the steaks after searing them, or right before serving. The other school simply seasons their steaks with freshly ground black pepper before cooking and doesn't give it a second thought.

When the grill is cool, remove the grates and flavorizer bars and put them into a full bucket of soapy water. Let them soak for at least 15 minutes. Remove anything else from the grill that you can take off without tools, like burner control knobs and the grease tray. This will make it easier to clean. Most gas grill burner tubes are removable as well (look for simple cotter pins on one end, although some models use screws).
