This $11 Must-Have Protects Your Grill From Pests, Mold, and Rust Over Winter – It's the Quick Fix That Saves Hours of Work Next Summer
It takes more than a good cover to protect over winter
As summer starts to wind down and cooler fall weather creeps in, grilling season begins to come to an end. But that doesn’t mean your grill can be forgotten until next year.
As laborious as it may sound, cleaning your grill and preparing it for winter is essential if you want to keep the same setup in good shape for years to come. A little maintenance now can save you time, money, and plenty of scrubbing when grilling season rolls around again.
And the secret to keeping those grates in good condition? Seasoning. It’s not just a pre-cooking ritual; a bottle of grapeseed oil from Amazon can help protect your grill grates from moisture and rust while they sit unused through the colder months, making for a much easier return to outdoor cooking next spring. Here’s how.
Grapeseed oil is one of the best choices for seasoning cookware, whether it is your skillet or our grill grates. The high smoke point means that it does not burn easily when heated, while the neutral flavor doesn't affect overall taste.
Seasoning a grill is common practice when preparing a grill after winter to prevent food from sticking and burning, but it is actually one of the best things you can do before, too.
Seasoning and cleaning cast iron, when done correctly, creates a hydrophobic barrier that blocks out humidity, condensation, and water, preventing rust and corrosion on metal grates. When you open it up again come springtime, they will be ready for a quick clean and cookout.
While you can remove rust and restore cast iron, prevention is always better than the cure. Seasoning before you pack everything away at the end of the season protects the structural integrity of your grates and will take less time than scrubbing rust spots when you want to start cooking. Trust me, it is more than worth the effort in the end.
The trick is to use a high-smoke-point oil, such as grapeseed oil from Walmart, to coat the clean grates before heating them until the oil is baked on. This helps create a protective barrier against moisture and rust while also helping to eliminate lingering food residue that could attract mold or pests over the winter.
As Grilling Expert Dylan Clay of Barbeque FAQ explains, 'In terms of oils, all you’re doing is avoiding ones that have a low smoke point. Those are things like butter, olive oil, extra virgin olive oil, etc. Anything neutral, such as grapeseed, vegetable oil, avocado oil, even Crisco, works. I prefer grapeseed − it's cheap and neutral.
'To re-season, apply a super-thin (thinner than you think you need) layer of oil or fat to all surfaces, and then even wipe off the excess. Bake at around 450-500 degrees Fahrenheit for one hour.'
Finish with a well-fitting grill cover, and your barbecue will be protected through the colder months and ready to fire up when the first warm day of next summer arrives.
