FAQ
Deep-clean a gas grill two to three times per year — typically at the start of grilling season, mid-summer, and before storing it for winter. If you grill more than once a week, lean toward three times. A full teardown (grates, Flavorizer bars, firebox, drip tray) every few months prevents grease buildup that causes flare-ups and shortens the life of your burner tubes.
Preheat the grill for 10–15 minutes to char off food residue, then use a bristle-free brush or a crumpled ball of foil held in tongs to scrub the grates. For stuck-on carbon, pull the grates and soak them in hot soapy water for 20–30 minutes, then scrub with a non-wire pad. Avoid wire brushes — bristles can break off and transfer to food.
Not on cast-iron grates — oven cleaner strips the seasoning you need to keep them rust-free. On porcelain-coated or stainless grates it can work if you rinse thoroughly, but a soak in hot soapy water plus a stiff non-wire brush is safer and avoids any chemical residue. Check the grate material before reaching for a cleaner.
The method depends on the grate material. For bare steel or cast iron, scrub with a non-wire brush and a paste of baking soda and water, then rinse, dry thoroughly, and re-season with a thin coat of high-smoke-point oil. For porcelain-coated grates, use only a soft cloth or sponge — aggressive scrubbing chips the coating and exposes bare metal to more rust. Replace any grate with deep pitting or flaking coating.
