I’m a fan of grilling all year round — even in the snow and ice of winter — but many people pack up their grills in the fall. If you’re someone who puts your grill away for the six cold months, consider the idea of not giving your grill a hardcore cleaning before putting it into storage.
The baked on crust that surrounds the metal on your grill grate will help protect the grate from rusting during the winter months. Rust can’t oxidize the metal grate if air and water aren’t able to directly come into contact with it. Instead of scrubbing the metal until it shines, take a clean, dry, cotton rag and wipe off all the large food crumbs and burned bits, but leave the black coating intact on the grate. Next spring, when you start up your grill for the first time, you can heat up the grate over the fire for 10 minutes and then scrub the grate thoroughly with a metal grill brush over the open flame (obviously wearing a really good oven mitt and using a grill brush that is up for the job). Fight the urge to do this type of deep cleaning now, though.
If you have a charcoal grill, you’ll want to empty any remaining ashes out of the bottom of your grill before storing it for the winter months. Please, be smart and only empty cold ashes from your grill so as not to hurt yourself or start a fire. Once the ashes are removed, use the same dry, cotton rag you used on the metal grate and wipe out the inside of the grill. It doesn’t need to be sparkling clean, you just want most of the ash out of the kettle of your grill. Again, the remaining ash will protect the interior of your grill from rusting during the winter months.
If you use a gas or electric grill, you can also use the dry, cotton rag to wipe down the cooking elements on the inside of your grill. Be careful not to damage them — a light touch is all you need. Gas grill owners will want to disconnect the tanks from the grill and return the empty to the rental company for a voucher. The voucher will let you start back up in the spring without having to pay another deposit for the tanks, and you won’t have to worry about storing the gas tank over the winter (something that can be dangerous if the tank isn’t completely empty).
You may want to dust off the exterior of your grill before storing it, but this step isn’t even all that important. It is important, however, that you cover your grill with a grill cover. The grill cover isn’t perfect, but it will help to keep most moisture out of your grill while it’s not in use. Moisture is the grill’s most common enemy, and you want to protect your grill from this adversary.
What you can give a good cleaning are all your grilling utensils. If any items need replacing, you may want to replace them now so you’ll be ready to go on the first warm day of spring. I like to replace the metal grill brush annually.
