Cleaning Your Grill Grates: Buying Guide, Reviews, And Ratings
"Last year's grease on the grill, last year's ashes on the bottom. That's what makes a Bundy Burger special." Al Bundy, Married With Children, 1989
Grease and oils get rancid, particularly in hot weather, and rancid grease on your grill grates can make your food taste bad. Rancid grease on the bottom of the grates can vaporize and flavor the food, too. Then there's the black crust. It is mostly carbon and it tastes like burnt toast.
It is vital that your food go on clean grates. Before you cook, get the grates ripping hot, close the hood, wait about 15 minutes or until the smoke subsides. That's grease smoke and it does not enhance flavor like wood smoke. It coats the meat with acrid soot. The heat will burn off the grease and turn any food or sauce bits to carbon.
A better practice is to clean after a cook to discourage insects from hanging around between cooks. Letting charcoal burn itself out and carbonize food residue is a good practice, but leaving a gasser or pellet burner on can get you in trouble. If you are forgetful, as I am, especially after a meal and wine, it is easy to accidentally leave the grill run all night and burn through a bottle of propane or a bag of pellets, so either set an alarm or just shut down when you bring in the food.
I start with a scraper like GrillFloss (below) and then I dip a stainless steel wire brush (below) in water and scrub with the wet brush, creating steam in the process. Then I follow up with a damp cloth to pick up any dust, chunks,or wire bristles left behind. You may want to try a handheld steam cleaner for both your grates and the interior of your grill. A mild enzymatic cleaner like Dawn Grill Cleaner is probably safer than a chemical cleaner whose residue could be noxious.
If your grates are reversible, flip them over between cooks. That will keep glop from building up on the underside.
Be careful with bristle brushes, especially cheap brass bristle brushes. Bristles fall out. Every year there are scores of sad news stories about people eating meals with bristles hiding on them. The bristle gets stuck in their throats or digestive systems, and repairs can get pretty ugly. Every so often someone dies. Here's an article on the subject from the Center for Disease Control documenting six (!) cases in Providence, RI, in one hospital system in 15 months! The X-rays here are from that article. Think I'm making a big deal out of nothing? Google "grill brush wire stuck throat".
So be sure to look your cooking surface over after brushing or give it a quick wipe with a damp cloth. I've even had readers tell me they run a half an onion or lemon over the grates after brushing. Make sure you have a good bright light pointed at your cooking surface.
If you have a lot of stubborn grease, lay a sheet of heavy duty aluminum foil on top of the grates, put some weights on it so it doesn't float up with the hot air, and let the fire rip for five minutes. Then use tongs to remove the foil, crumple it, grasp the wad of foil in the tongs, and scrub the grates.
When you are done cooking, if you have a gasser or pellet burner, it is a good idea to leave them on to burn off gunk, then scrape them. If you are forgetful, as I am, you can accidentally leave them run all night and burn through a bottle of propane or a bag of pellets, so set an alarm.
Do not run grates through the dishwasher! The grease is pernicious and can coat everything inside the diswasher, and you'll be sleeping on the couch for a while. Periodically take the grates off the grill and lay them on a cloth on the ground. Fill a bucket with hot water and dish detergent. With a brush, scrub both sides and rinse thoroughly. Be warned, if you do this on cast iron it will likely lose some of its non-stick properties, but sometimes, especially if there is rust, you have no choice. Just make sure you thoroughly dry and oil cast iron after washing. You can use a scrubby sponge, and even steel wool on stainless and plated if it has not been chipped.
The AmazingRibs.com science advisor, Dr. Greg Blonder, says "My end-of-year clean is to place the grates in a large tub, pour on boiling hot water, mix in some Dawn, and come back the next day. Cleans off easily with a stainless steel scrubby." My end-of-season clean is with a pressure washer and then dish soap.
Recommended scrubbers and brushes
Alas, there is no single tool that does the job perfectly. Here are some of the options.
Weber 18-Inch Bamboo Grill Brush . Still the easiest, and most effective way to remove grease. Heat the grates and then brush. Simple. There are a variety of brushes like this with rustproof brass bristles but the Weber is my favorite because it is well built. Some have flat scrapers on the end as well as the brush. I like this model because the C shaped scraper on the end.
The Last Brush. This long handled tool is perfect if you have a deep barbecue pit or catering rig. With two inch bristles that appear to be well anchored into the wood head, there is also a steel scraper, a 36" long wooden handle, and a leather strap for hanging.
US Forge Welding Stainless Steel Wire Brush. This is my go to tool. The bristles are stainless so they won't rust if I dunk them in water or leave them out in the rain. They're good and stiff for dislodging stubborn carbon deposits, and the narrow ones fit perfectly into the valleys of GrillGrates. They are anchored to the wooden handle well enough that I've never had a bristle pop out (I have seen them come out of plastic handles).
Billy Bar. This simple C-tipped device does a great job of cleaning the sides and undersides of the grates. Made with a wooden handle and sturdy coated steel that the manufacturer claims will never rust, it is 23" long so you can use it on a hot grill without burning your hand. The angled tip makes it easier to get the parts a brush cannot reach. The only downside is that it takes a few seconds to do each grate, and on a big grill, this can get old in a hurry when you are hungry.
This is the heavy artillery. I use mine once a year to deep clean and more often on the deflector plates on my pellet smokers. These steel plates lie directlyu below the cooking grates and gan get mighty greasy. Steam does the trick. Also come in handy in the kitchen and bathroom!
Grillfloss. Similar to the Billy Bar, the angled head makes getting the sides and undersides of grates easier. There are two semicircular scraping surface that fit all thicknesses. Like the Billy Bar, this takes time. The biggest problem is that the tip is not very thick and it can bend and eventually break. You can buy replacement tips, but I would prefer to start out with a sturdy one.
A block of wood. You can build your own by simply taking a block of wood and a heat-proof glove and rubbing the wood on the grates. If you do it right, eventually you will wear grooves in the wood that fit the grates perfectly. But a block will not get the underside.
Aluminum foil. Take a big ole wad of foil, put on a heat-proof glove, and scrub. You need heat proof gloves, and more than one wad, which has to be thrown out.
GrillStone Grill Cleaner Starter Set, with Handle and Two Blocks . These pumice-like bricks are great for cleaning wire cooking grate. Do not use them on porcelain or cast iron grates. They are very fast, much faster than Grill Floss or Billy Bars, but they get only the tops. Each brick will scrub about 100 grates before it wears out. They are made from ground recycled glass and they leave a bit of dust behind, so you need a brush to finish the job. It's the microscopic glass dust that makes me nervous. There are other brands of Grill Bricks available.
Tool Wizard BBQ Brush. This device uses a woven stainless steel pad that does a great job of cleaning the grates. At first. It sounds great in theory, and it gets good reviews from others who haven't really used it, but performance is another thing. In theory the scrubber can be removed and run through the dishwasher, but if it is greasy, it can really slime the dishwasher and anything in there. When the scrubber gets disgusting and starts falling apart you can buy replacements, but they are not cheap, and they break down quickly. Before long it begins to slide side to side and unravel. You have to be careful, because when it starts to disintegrate, the woven steel can fall off onto the grill and could get into your food.
T-Brush. This is a large brass-wire brush that used to be one of my faves until it started shedding bristles. The bristles are not glued in, they are held in by twists in a metal bar connected to the handle. Once one or two fall out, the rest come loose more easily. It is very rare, but there have been choking incidents when bristles on the grate got onto food and were ingested.
Scrub & Spray Brushes. These look great on paper. There are replaceable stainless steel brushes and you can drip water while you scrub creating steam. Alas, in practice, I was unimpressed. You have to fill it with water, open a small spigot, scrub, and close the spigot. I didn't think the steam made that much of a difference. I get better results with a simple brush dipped in water. And in winter the water freezes unless you empty it after each use or store it in the house, and nobody wants a greasy grill brush in the house. Besides, I'm always wary of replaceable brush scrubbers. Last time I bought one, at a premium price, the company went out of business within six months.
