Grill grates are like most cooking appliances that food touches. If not cleaned properly, bacteria will make it their home, potentially making you, your family and your guests sick. That can be a big downer during your summer outdoor grilling parties.

Grill grates are typically made of stainless steel or cast iron, and are often porcelain coated. Stainless steel grates can handle more vigorous cleaning compared to porcelain, which can be easily scratched. It’s important to use soft brushes on porcelain and make sure the grates are dry after cleaning to avoid rust.

Cast iron grates can be cleaned with a ball of tin foil, or a cleaning brush and dish soap for tough areas. Cast iron grates without an enamel coating run a higher risk of rusting, so be sure to completely dry those after cleaning as well.

Grates should be cleaned after every use; it’s quick and easy. First, heat the grill all the way to burn off anything left on the grates. Then turn it off and wait a few minutes. While the grates are still warm, remove residue with an appropriate scraper and brush.

Ideally, you should deep clean your grill once a year to prevent dirt, food and grease buildup. Here’s an effective and safe way to deep clean your grill grates:
