Keeping A Grill From Rusting Out

How To Keep A Grill From Rusting Out? There’s nothing wrong with having some texture in your meat — unless the texture is caused by rust. When a grill’s grate becomes rusted, the rust can easily migrate to the food you’re cooking on it.

That might mean biting into rusted metal. Not only is the flavor and texture revolting, but it can also be harmful to one’s health. Rust is merely the beginning of the deteriorating process.

If you leave a rust problem on your grill unattended for too long, it may suffer structural damage and eventually break down. The good thing is that keeping your grill rust-free is a straightforward operation.

How To Prevent Rusting On A Grill

If your grill is now rust-free, the following suggestions will help maintain it that way. These are the things to do and avoid if you want your grill to last as long as possible.

  1. Do Not Allow The Grill Grates To Become Wet

Grilling or smoking a great meal without getting the grill grates wet is difficult. We always use some marinade, glaze, or sauce at Mad Backyard. Even the juices from your meat will saturate the barbecue grates while they cook. The aim is not to leave them wet after you’re through.

Turn the burners up or open the vents all the way and let the temperature climb as high as you can for a good 10 minutes after you remove the meat. The grates should start to dry out and turn ashy at this time, and you may turn down the heat and clean the grates with a good quality bristle-free brush. Then close the lid, wait for the grill to cool, and replace the covering.

  1. Take Action Quickly To Keep A Grill From Rusting Out

If you notice signs of rust, don’t spend any time. Once the rust has cooled, you should remove it quickly. The longer you leave, the worse the problem will become. Rust spreads much more rapidly than you may imagine.

  1. Lubricate To Keep A Grill From Rusting Out

You’ll need to oil your grill if you want it to run like a well-oiled machine. Professionals always recommend rubbing vegetable oil on your grates after a thorough cleaning, just like when seasoning a new grill or smoker.

What’s The Deal With Veggie Oil

It’s food-safe, eco-friendly, and cost-effective, and it gets the job done correctly. It will coat your grates in a protective layer that will keep rust at bay while still providing a safe cooking surface.

Obtain a rag and a small amount of vegetable oil. You want to apply a thin, even layer that isn’t too thick. You might also work the oil into the grate with a soft brush.

  1. Wrap It Up And Put It

Anything you do to prevent rust will be for naught if you don’t cover and store your barbecue properly. The humidity in the air will wreak havoc on your grill. It could be raining, snowing, or even a hot day. This is useful for people who live near a body of water or in humid climates.

A lid is standard on grills, but it’s not what we’re talking about here. A suitable vinyl or nylon cover that fits snugly around your grill is the way to go. If the cover contains a textile inner for added strength and longevity, you’ll get bonus points.

  1. Remove The Drip Tray And Drain It

Hopefully, you’ve noticed that your barbecue has a drip tray underneath it to capture greasy meat drippings. This is something you should verify before and after each cook on a frequent basis. It’s time to drain it when it’s too full of water, grease, and debris. It would be best if you double-checked your drip tray after any rain. If this fills up with water and sits, it will rust your grill soon.

  1. Don’t Forget To Keep It Clean

Keeping up with your regular cleanings is a specific strategy to keep rust at bay. Every time you use your barbecue, give it a quick cleaning.

To remove the particles stuck on your grill grates, use a mild grill brush. A firm metal brush, on the other hand, might scratch the grates and cause your grill to rust faster.

Grease The Grill Grates

After cleaning, coat all sorts of grill grates with vegetable oil to prevent food from sticking to them in the future. The oil also repels moisture, so it helps prevent rust. 

Do not use an aerosol can of vegetable oil, however, as aerosol cans occasionally explode when used near a fire. Apply a thin layer of oil to a dishrag and use it to coat the grill.

Cover The Grill Grate & Move It Indoors

The main cause of rusting your grill grates is water. When the grilling season is over, cover it with a nylon or vinyl cover with a cloth lining.

If there is high humidity, heavy rainfall, or snow, bring the portable grill inside or put it in a covered shed. It is especially important to clean and cover your grill if you live near the ocean, as the high level of salt may also corrode it.

Are Grill Covers Effective At Preventing Rusting

You can protect your outdoor grill from rust by investing in a grill cover. It is protected by flexible and durable materials that can withstand different climates. Once you have used the grill, always cover it. By doing so, it will reduce the grill’s exposure to air, which will extend its lifespan. 

If you live in a humid area, moisture might still get under the cover. In this case, you need to check your grill regularly for moisture. 

  1.  Replace it if Grated To Keep A Grill From Rusting Out

Your grates will most likely rust first, followed by the rest of the grill. And if the rust on them gets out of hand, it can quickly migrate to other elements of the grill, making replacement more difficult.

When your grates aren’t looking any better after you clean them or are starting to corrode and decay, it’s often preferable to bite the bullet and buy some new ones. Before you purchase unique grates, make sure you measure twice and buy one to ensure they will fit your grill/grill correctly.


If you would like to increase the life span of your grill, you must understand how to maintain a grill from rusting. Because if your grill begins to deteriorate, the corrosive rust will contaminate your meal. As a result, it’s a good idea to inspect and clean your grill before each cooking season. Follow our methods and directions – it will take some time to clean up, but the end result will be much better.
