There are a few ways to clean a cast iron BBQ grill. You can use baking soda paste or vinegar to remove rust build-up. Just apply the paste on the build-up and scrub it off with an abrasive surface. This method should work in most cases.

Salt and vinegar

It is important to clean your cast iron grill regularly to prevent rust and damage. While cleaning with soap can remove stains, it will not remove the rust. Using a mixture of vinegar and salt can be an effective cleaning solution. Be sure to wear old clothes while using this method. Soak the grill overnight or more, depending on the degree of rust. After soaking, scrape off rust with steel wool.

Vinegar contains acetic acid, which is an excellent cleaning agent. When combined with table salt, it acts like a powerful rust remover. The acidic nature of vinegar also makes it suitable for cleaning many surfaces around the house. The solution can be applied to the exterior of the grill as well as its interior to remove dirt and grime.

Hot water and washing-up liquid are also useful tools for cleaning your grill. These solutions are safe to use and remove any traces of oil, grease, and stains. They work by dissolving organic substances and grease, and can easily be applied with a scourer sponge.

Another option is to use a baking soda-and-vinegar paste. This mixture will remove surface rust from your grill. You can apply the paste to the rusted areas of the grill and scrub the rust away. If the rust is stubborn, you may also need to use baking soda paste.

You can also spray a mixture of vinegar and water onto the grill grates. The solution will break up the oil and kill harmful germs left by raw meat. Alternatively, you can spray the mixture onto a piece of foil and scrub the grates with it. This method is less effective and can leave a sticky residue on your grill grate.

Oven cleaner

The first step in cleaning a cast iron barbecue grill is to empty all of the food and grease that has built up on it. You can do this with a standard oven cleaner or a special grill cleaner. Either one works well, and is effective in removing rust, baked-on crud, and other food particles. Oven cleaners typically contain lye, which is a strong alkaline solution. The solution should be applied to the grates of the grill and stored in a warm area for at least two days.

You can also use baking soda to clean the grill. This can be applied to the grates and then rinsed. Then, you can reseason the cast iron by using vinegar. Vinegar is also a good option for cleaning gas stove grates and cast iron barbecue grills. It has the advantage of being non-toxic, which makes it an ideal choice for cleaning.

Before cleaning a cast iron barbecue grill, you need to oil the grill grates. It is best to use flaxseed oil rather than vegetable oil. After that, you need to heat the surfaces of the grill to 200 degrees Fahrenheit for about 15 minutes to allow the oil to penetrate. After that, you need to use hot soapy water to remove any grease or food, as well as the sudsy residue.

For rust-free grills, you can use a steel bristle brush. This will help to scrub away the remaining rust. However, if you use a brush, you should make sure to scrub the grates before applying any high-temperature oil. Oven cleaners contain harsh chemicals, which are not the best choice for a grill with grates that have been exposed to a lot of moisture.


You can season your cast iron barbecue grill to improve its performance. To do this, first heat your grill to 200 degrees Fahrenheit and clean the grates. Brush the grates with a steel brush to remove any rust and residue. After this, use a paper towel to rub a thin layer of oil over the grates. Avoid using nonstick spray, because it can cause stickiness. Instead, use vegetable oil to season your cast iron grill.

You can use any vegetable oil blend to season your cast iron barbecue grill. Choose neutral flavored oils with high smoke points. Canola oil, peanut oil, and vegetable oil are all fine choices. You can also use a specialized oil like Crispee Puck. You’ll need about half a cup to season a cast iron barbecue grill.

Another method for seasoning your grill is to place it in a warm oven and bake it for 30 minutes. You can also place a cookie sheet below the cast iron grid to prevent it from scorching. Then, remove the grill and allow it to cool. Repeat this process several times until the grill is thoroughly seasoned. This process will ensure that your grill’s grates won’t stick to foods and won’t rust.

Oiling the grates is also a good idea. This will protect the grates from rust and make cleanup easier. The oil will also prevent food from sticking to the grates and make them nonstick. As long as you’re careful, you can enjoy your cast iron barbecue grill for many years to come.

After the oil is applied, use a paper towel to wipe off the excess oil. The oil should cover the grates evenly. Allow the oil to cook for about 30 minutes before removing it. The grates should become dark in color as the oil and smoke begin to work their magic. This will impart your grill with its signature flavor.

After-cooking care

Cast iron barbecue grills require after-cooking care to keep them in good condition. This cleaning process must be done as soon as possible to avoid food and grease from setting on the grates. It is also best to wait at least 10 minutes after cleaning to ensure that no grease or food remains on the grill.

Clean the cooking grates using warm water and mild dish soap. Use a clean cloth to dry the grates. Once the grates are clean, apply a thin layer of oil to the grates. The residual heat will bake the oil into the cast iron. The grill should be cool to the touch before applying oil to it.

Season the grates with vegetable oil or cast iron seasoning. If you do not have a brush, you can use a paper towel. You can also dip a paper towel in cooking oil and rub it on the grates. Be careful not to get too oily or you might end up with smoke on your hands.

The grates should also be brushed with vegetable or olive oil before cleaning. If the stuck-on bits are stubborn, you can use steel wool or water and mild dish soap. To prevent any further damage, you can also rub vegetable oil on the grates after cooking. Make sure to wear gloves when cleaning to avoid scratching the grill.

Cast iron barbecue grills need to be cleaned after every use to keep them in good condition. Cast iron gets better with age, and you can add seasonings to your cooking to make it taste even better.

Cleaning with a brush

A brush works great for cleaning a cast iron barbecue grill, but you must be careful that the bristles don’t damage the surface. You can purchase brushes with nylon attachments that won’t damage the surface. Another option is to purchase an extender to reach into tight areas.

First, you need to empty the water. You should use clean water and dish soap. Next, use a large kitchen sponge to scrub the outside of the grill. Avoid using a metal sponge or scouring pad, because these can scratch the surface. Once the outside of the grill is clean, use a super absorbent microfiber towel to wipe it down.

You can also use a commercial oven cleaner. Generally, this cleaner contains lye, which is strong enough to unclog drains and remove heavy rust buildup on cast iron grill grates. Be sure to use protective gloves and safety glasses when using this cleaner, and use a container that is large enough to hold the grates. Once you’ve completed cleaning the grill, store it in a warm, dry place for at least two days.

If you’re looking for a budget-friendly brush that won’t sacrifice quality, you’ll want to try the Backyard Dudes BBQ Brass Brush. While brass bristles won’t withstand as much heat as the nylon bristles, they will still be tough enough to clean your grill.

The grates on a cast iron barbecue grill need regular care to stay clean and rust-free. By regularly cleaning them with a brush, you’ll be able to enjoy using it for many years to come. And after all, the results are well worth the effort!
