1. Loosen any surface rust from your grill
First things first, let's tackle that pesky surface rust. Armed with a wire brush or steel wool, gently scrub away the rust from the surface of your grill. This will help to loosen any stubborn spots and prepare the grill for a deeper clean.
Rafi Friedman, CEO of Coastal Luxury Outdoors, says, "Your most important tool here is going to be a good grill brush. Grills tend to have quite a lot of burnt-on carbonized gunk, so you'll want something that will stand up to heavy use."
Rafi recommends the GRILLART Grill Brush & Scraper from Amazon as a great grill-scraping option.
He adds, "Start by getting as much gunk off as you can with your grill brush before you apply any cleaner. This will help a lot when it's time to soak the grill grates, since it will keep all of that black, carbonized food out of the water."

2. Soak your grill overnight
If you want to barbecue right, you'll want to give your grill a good soak to penetrate those hard-to-reach, rusty spots.
Rafi says, "Once you've scraped as much as you can, fill a large bucket or plastic tub with hot water and then make a paste consisting of one cup of dish soap and 1/4 cup of baking soda. Apply the paste liberally to the grill grates, then set them in the water to soak."
We recommend Arm & Hammer Pure Baking Soda from Walmart.
If you don't have a bucket or tub large enough, a sturdy garbage bag does the job — just be careful not to get yourself soaked. You want to submerge your grill grates, but don't overfill with water or you risk over-diluting your solution.
An alternative, equally-effective solution is salt and vinegar. Not only is it America's most popular crisp flavor, but this pair combine brilliantly to rid your grill from rust and it's one of multiple ways to use vinegar to clean around the house.
Mix one cup salt with two cups white vinegar (such as the Good & Gather White Distilled Vinegar from Target). The salt will increase the natural acidity of the vinegar to the point where it can dissolve the already oxidized metal. The salt also acts as an abrasive when it comes time to start scrubbing.
Choose the solution that works best for you and the products you have to hand. Unless you're in a rush (in which case, an hour can do the job), leave your grill to soak overnight — working its rust-banishing magic while you catch some Zs.
3. Scrub the grill
With the rust loosened and softened from its overnight soak, it's time to give your grill a good scrub. After all, not cleaning properly tops the list of major mistakes that will ruin your grill.
For this step, a paste made from baking soda and water works wonders. The baking soda acts as a gentle abrasive, helping to lift away the remaining rust and restore the surface of your grill to its former glory.
Apply the paste to the rusted areas of your grill and scrub vigorously with a nylon brush or sponge. The Royal Gourmet Cleaning Brush from Wayfair has both scraper and scouring brush and works brilliantly on porcelain, ceramic, iron and steel BBQs.
Alternatively, you can opt for a commercial rust-remover such as the Rust-Oleum Rust Dissolver Gel from Amazon.
Vanessa Bossart, founder of GreenTerra Cleaning, says, "There are several effective rust-removal products out there, like Bar Keepers Friend Soft Cleanser from Target. This acid-based solution effectively removes rust without damaging the grill’s surface."
4. Rinse, dry and protect your grill
Once you've scrubbed away the rust, it's time to give your grill a thorough rinse to remove any remaining residue.
Use a hose or bucket of water to rinse away the baking soda paste or rust-remover. Be sure to dry your grill thoroughly with a clean cloth or towel to prevent any new rust from forming. These Prep & Savour Cleaning Cloths from Wayfair will do the job nicely.
Vanessa says, "Rinsing and drying the grill thoroughly is critical to ensure any residual chemicals or cleaning products have been removed prior to your next grilling session."
To keep your grill well-maintained, remember the three Cs: clean, cover and coat.
Clean your grill regularly to remove grease and food debris, which can contribute to rust formation. Cover your grill between uses to protect it from the elements (we have plenty of ideas for guarding your grill in style). Coat it with cooking oil (try Amazon's Happy Belly Soybean Vegetable Oil) after each clean to prevent rust formation.
Vanessa adds, "The CitraSolv Valencia Orange Cleaner and Degreaser from Walmart is another great option to guard against moisture and future rust. It both cleans and leaves a protective coating, enhancing the grill's longevity."
So there you have it — with these simple steps and top tips in mind, you'll have your outdoor grill rust-free and looking sizzle-worthy in no time.
