The Patrol’s rule: a clean grill is a safe grill. Grease and carbon are what turn a normal cook into a flare-up or a grease fire, so this routine is safety first, shine second.
Every cook
- Brush the grates while they are still warm, not screaming hot. Warm grease lifts off easily, and a blazing-hot grate is harder on your hand and warps over time. Use a bristle-free brush or scraper only. We do not recommend wire-bristle brushes at any price: a stray metal bristle in your food is an ER trip, full stop.
- Wipe the grate with a damp cloth once it cools. This carries off the residue the brush broke loose.
Monthly, or whenever buildup shows
- Pull the grates and soak them in hot, soapy water. For baked-on carbon, reach for a dedicated grill degreaser instead of scrubbing harder. On porcelain-coated grates, never use a metal scraper or wire brush, which chips the coating and starts rust.
- Empty the ash (charcoal) or the grease tray (gas). A full grease tray is the number-one cause of grease fires. Empty it before it overflows, not after.
- Check the burner ports (gas) or air vents (charcoal) are clear. Blocked ports cause uneven heat and flare-ups; clear them with a thin wire or a toothpick.
Gas vs charcoal
- Gas: watch the grease tray and burner ports. Most gas flare-ups trace back to a tray nobody emptied.
- Charcoal: clear the ash after every cook. Ash smothers airflow and traps moisture that rusts the bowl.
The Guardian’s 30-second inspection
Before you light it: grates brushed, grease tray empty, ports clear, no loose bristles on the grate. Four checks pass, you are clear to cook.
