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.
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.
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.
Grilling season is upon us, which means summer cookouts, burgers and barbecue, and long, warm nights in the yard. It also means it’s time to clean your grill. The same cooking process that makes those Instagram-perfect, flavorful char marks on your food produces carbon deposits on virtually every interior surface of your grill: the grates, flavorizing bars and burner tubes (on gas grills), and the firebox itself. Those carbon deposits aren’t just ugly; grease can stick to them and harbor bacteria, and carbon buildup can cause your grill to heat unevenly or prevent it from reaching full operating temperature, and burner tubes to fail.
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.[12] Remove the burners and venturi tubes, and place a hose head at one end of the tube.[13] Turn the water on to clear out any debris or insects that could have gotten inside.
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.
Transfer the steaks to cooling racks with a sheet pan or cookie sheet underneath, cover the whole tray with plastic wrap and stick them in the fridge. Take them out about 30 minutes before cooking, pat them dry again with paper towels (because the salt will pull out some juices), season with freshly ground black pepper (press the pepper into the meat as you did with the salt) and then grill as you normally would. We'll talk more about black pepper in a moment. As for patting the steaks dry, a dry steak will form a browner crust when it's cooked.
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.

There are a ton of different grill cleaning gizmos to choose from, but nothing can beat a long handled wire brush, a wire bottle-style brush, a five-gallon bucket, and some elbow grease. Avoid toxic cleaning formulas. They can impart an off taste to foods, and aren’t necessary: warm water and dish soap and a paste of vinegar and baking soda are all the cleaning power you need. If your grill has stainless steel exterior surfaces, a good stainless steel cleaner (or vinegar) imparts an extra shine. You’ll also need some durable gloves and a few disposable sponges and rags. Pick an overcast day; hot sun can make it hard to remove streaks from cleaners (plus, it’s cooler working weather).
