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.
The trick with seafood is to make sure it doesn’t stick. So coat it lightly with oil and check that the grate is clean and very hot. For fillets and whole fish, you can also try this foolproof (albeit more time-consuming) method: Place the fish on a soaked cedar plank or a lightly oiled piece of heavy-duty foil, then grill (covered), over medium indirect heat.
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.
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.
Clean the bottom of the grill with a soapy sponge. Once all the chunks are gone, scrub the bottom with a sponge or scouring pad and soapy water to remove any built up grease or grime. Lots of drippings and food scraps tend to build up under the burners of the grill. Pay close attention to this area and clean it as much as possible to avoid corrosion.
