These are the workhorses of your cooker and because they come in direct contact with your food, they need to be clean. Start by removing the cool grates and wiping or brushing off as much of the big, loose debris as you can with a mesh or nylon scrub pad or a brush. In a sink or large bucket, mix up a sudsy solution of a grease-cutting dish liquid, like Dawn, and hot water and place the grates in to soak. If they don’t completely fit in, immerse one half, soak, then flip it over to get the other side. After soaking 15 to 30 minutes, put on some rubber gloves (like GH Seal holder, Playtex) and scrub the grates clean with a sturdy grill brush or scrubbing pad. Take extra care with porcelain grates, because you don't want to damage them.
It seems that people approach grilling steak one of two ways: either in a casual manner or paying perhaps too much attention. Some will heat the grill with abandon, throw the steaks on, flip once, then pull them off, and serve; others will fret and worry, cutting into the meat every two seconds wringing their hands over whether the meat is done or not. Both techniques do have some merits but a method somewhere in the middle is ideal.
When finished, you’ll have ears of corn with varying degrees of husk and silk clinging to golden, lightly charred corn and you’ll probably be wondering how the heck to husk it. Remove the ears from the grill and cool for five minutes. Then you should be able to easily pull back the husks and silk. Use a clean kitchen towel to wipe away any unwanted silk or charred husk flakes.
Certain practices can help discourage deposits of dirt and grease from forming in the first place. One method is to grease the grates of your hot grill with a little cooking oil right before your start cooking. In the same vein, scrubbing your grill grates with a raw onion is another tactic you can try. If you do have a grill brush without bristles, it's a good idea to scrape your hot grates both before and after grilling.
You also want a cooler, medium heat area of the grill to move the steaks to once they're seared and crispy on the outside. If you have enough burners and space on your grill, set them to a lower heat; if you don't have enough room, simply turn off the burner. If you are using a charcoal grill, one side should have a hot fire while the other a smaller, cooler flame.
There's another debate about seasoning steaks, and this one relates to black pepper. To begin with, let's agree that freshly ground black pepper is a must for the perfect steak. (And again, we're not talking about that preground black dust they sell at the grocery store. We mean whole black peppercorns that you grind yourself directly onto the steak.)
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.
