Deep cleaning grill grates involves either a high-heat burn-off combined with a foil scrub or an overnight soak in a degreasing solution. This breaks down baked-on carbon and greasy buildup without using dangerous wire brushes.
Moisten the grill grate with water. Sprinkle ARM & HAMMER Baking Soda liberally over the stainless steel grates and let sit for 10 minutes. Using a damp scourer sponge, scrub the grate going up and down each wire. Rinse with water and return the grate to the grill.
To clean your gas stove's cast iron grates, soak them in hot, soapy water to loosen grease. Scrub with a stiff nylon brush or a non-scratch pad, make a baking soda paste for stubborn spots, and rinse. Dry them thoroughly to prevent rust, then lightly oil to re-season them.
In a large utility sink or plastic tub, mix regular table salt with distilled white vinegar in a 1:2 ratio. Lay the grates in the mixture and allow them to soak overnight. In the morning, you'll see that much of the rust has been dissolved. You can use steel wool or leftover salt to get rid of any remaining rust.
Yes, you can absolutely soak your grill grates in Dawn dish soap. Dawn is an excellent degreaser that breaks down tough, baked-on grease and food particles.
For a quick and natural clean, use a crumpled ball of aluminum foil to scrub warm grates. For a deeper clean, soak the grates in a trash bag with a mixture of baking soda and vinegar, then scrub with a scouring pad.
Using an onion to clean a grill relies on the onion's natural moisture and acidity to steam and lift grease, stuck-on food, and carbon from hot grates. This method provides several practical, culinary, and cultural benefits:
Ingesting a small amount of iron oxide (rust) is generally not harmful, but it is not food-safe. Rust can harbor bacteria and leave an unpleasant metallic, bitter taste on your food. It is highly recommended to clean, scrub, and re-season rusty grates before cooking.
Dawn does not chemically dissolve rust on its own, but it is an excellent tool for loosening and scrubbing away surface-level rust. Because Dawn breaks down grease and grime, it allows water and scouring pads to penetrate and lift rust off metal surfaces like griddles, tools, and hardware.
If your cast iron grates are seasoned, place them in the sink and soak in soapy water for 20 minutes. After they are done soaking, wipe the grates clean and thoroughly dry before placing them back on your stove.
Detergents aren't made with lye, so can't be soap. Either way you still shouldn't use soap with cast iron, but can use detergents, though there is no reason to do so. You can easily clean well maintained cast iron without it.
Scrub with a pasty mixture of baking soda and dish soap. Combining this method with a crumpled ball of aluminum foil really helps get into those hard-to-reach grooves. If you're not bothered by using chemicals, Easy Off works great as well. (Just be sure to wash them well with soap and water before cooking.)
Common Mistakes People Make When Cleaning Cast Iron Pots and Grates. Using abrasive cleaners, scouring pads, anything with bleach, and harsh detergents. These can damage the pan and the seasoning you've so carefully built up.
Rubbing a raw potato on a hot grill deposits a layer of starch onto the metal, creating a natural, non-stick barrier. This prevents delicate foods like fish, chicken, or vegetables from sticking to the grates and helps clean away leftover food residue.
To make grill grates look new, soak them in a mixture of hot water and baking soda or white vinegar for 30–60 minutes, then scrub with a heavy-duty scour pad or foil. For stubborn, baked-on grease, applying a paste of baking soda and soap, or sealing them in a trash bag with vinegar overnight, works best to restore a polished, clean finish.
Mistake 3: Soaking the Pan in Water
Cast iron rusts when exposed to moisture for long periods. A water soak can undo months of seasoning and require a full restoration. Wash quickly with warm water and a soft brush while the pan is still warm. Dry it immediately on low heat until all moisture evaporates.
Yes, vinegar reacts with cast iron because it is a mild acid, which can be both useful and harmful depending on the application. While it is excellent for dissolving rust in short-term applications, long-term contact will etch (eat away at) the metal, destroying the seasoning and causing permanent damage.
Option #2: Baking Soda and Vinegar
Grill grates can also be soaked overnight in vinegar to remove heavy rust. Use a shallow pan so that the grill grates are fully submerged. Spray or wipe vinegar onto the rusty grates. Sprinkle with baking soda and let it fizz.
Yes, a little bit of surface rust on cast iron is completely fine. It is not toxic and will not ruin your pan. Rust is just iron oxide, and tiny amounts are harmless. However, it can leave a metallic taste or cause food to stick, so it shouldn't be ignored forever.
Better yet, advises Prince, toss your wire grill brushes. “A number of people are injured by these wire bristles each year, and simply changing the way you clean your barbecue grill or other cooking surfaces can eliminate this risk completely,” he says. “Just stop using the wire bristle brush.
Rubbing an onion on a hot grill is a popular outdoor cooking hack that acts as a natural cleaning alternative to traditional wire brushes. It is used to loosen cooked-on grime, season the grates to help prevent sticking, and create an inviting aroma.
Hibachi chefs primarily use water or ice, a heavy-duty metal scraper, and a grill brick to clean their flat-top grills. Instead of using harsh chemical detergents, they rely on heat and steam to lift stuck-on grease and food.
Use an onion to scrub the grill grates
Did you know that you can use just half of an onion and a grill fork to scrub your grill grates clean? The heat of the grill paired with the natural antibacterial properties of the onion help to break down any stubborn char or sticky sauce.
