Clean the exterior of the grill. Soapy water is the safest cleaning solution for most gas grills.[3] Just make a cleaning solution with water and a squirt or two of mild dishwashing soap. Wipe the exterior of the grill with the soapy water, use a rag dipped in clean water to remove the soap residue, and then dry the exterior of the grill thoroughly.

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.

Like a boxing ring, it’s hard to knock out your opponent in the first round. Same goes for the Blackstone and the tension between the oil and steel. One round ain’t gonna cut it. To make the best non-sticking and tasty surface your meals deserve, you’re gonna have to repeat the seasoning. So be patient and make it count. Grab your oil again, dab it on the griddle, and watch the heated smoke-fest again. You should stop when the griddle plate is dark brown, and that takes around 2 to 3 times.
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.

Reassemble the grill, then turn it on to its highest temperature setting and close the hood. There may even be a cleaning level on your burner dials. After a few minutes, open the lid and scrape the grates vigorously with a non-bristle metal grill brush. One I particularly like is the $15 Grill Bristleless Scraper from Taylor. This brush has multiple surfaces and edges to attack and remove grime from grill grates. It even has a handy bottle opener. 
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.

Cookout season is just a few short weeks away, and if your gas or charcoal grill is still covered with the remnants of last year's cheeseburgers and Hawaiian chicken, now's the perfect time to give it a refresh as part of your spring cleaning routine. These speedy tips from the Good Housekeeping Institute Cleaning Lab come from years of testing outdoor grills as well as the cleaners and tools you need to keep them working well (and your food tasting great).


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.

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.
