Try to avoid this if you can, but if you just have to take a peek, remove the steak from the grill and use the tip of a paring knife to make a cut into the center of the steak to see how things are going. Keep in mind that the steak will continue to cook as it rests after being removed from the grill. Cutting into the steak is discouraged because it will release the precious juices that help flavor and tenderize the meat.
If you're salting right before cooking: Again, let the steaks sit at room temperature for 30 minutes, sprinkle both sides (and the edges) generously with Kosher salt and freshly ground black pepper. Press the salt crystals and pepper granules into the meat. We like to brush our steaks with a little bit of clarified butter right before we grill them. You could use a refined high-heat oil or a mixture of oil and clarified butter.

Inspect your burners for signs of corrosion or anything blocking the row of flame holes. Burner tubes are inviting spots for spiders to lay eggs if your grill goes unused for a while. Use a wire brush and clean them by brushing back and forth over the holes, not down the length of the tube. The wire bottle brush can clean out the inside of each tube.

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.
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.
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.
