How to Limit Rust on Grills

Prepare your gas or charcoal grill surface before cooking by spraying it lightly with non-stick cooking spray. Preparing the grill surface in this way keeps foods form sticking and charring. This reduces the amount of scrubbing necessary to get the grill clean, which cuts down on the possibility of scratches that can open the grill up to rust.

Clean your grill surface after each use with a piece of steal wool and some hot, soapy water. Make sure to get all the surfaces scrubbed down, including corners and crevices where cooking debris can hide. For stubborn debris, use a spray-on oven or grill cleaner according to the package’s directions. Keeping the grill clean helps cut down on build-up that can scratch the cooking surface, making it susceptible to rust.

Dry your grill surface thoroughly after cleaning and store it in a clean, dry place. If your grill surface is cast iron, heat the grill on low after cleaning the grill surface and allow the grill to dry with the heat. Cast iron can rust easily if there is any water left on the surface. Once the grill is thoroughly dry, re-season it by wiping it down with some vegetable oil on a paper towel.

Store your grill under a grill cover. Make sure the cover fits snuggly and is free of rips or tears where moisture can get through. If you store your grill outside during the winter months, it’s a good idea to put a tarp over the grill cover for extra protection.

Empty a charcoal grill after each use. Charcoal residue can hold moisture from rain or dew, which can quickly cause the bottom of the grill to rust. Dispose of used charcoal in yard waste bags after it has cooled completely, or save it in a dust bin and add it to flower beds to enrich the soil. Rinse the grill pan with water and wipe it down. Store it in a clean, dry place.
