How to Clean a Grill

After every cook (5 minutes)

1. Burn off residue. Run the grill on high with the lid closed for 10–15 minutes. Most food residue carbonizes to ash.
2. Brush the grates while hot. Use a coiled or nylon brush.
3. Drain or empty the grease tray if visibly full.
4. Cover the grill once cool. Don’t cover while hot.

Monthly (15 minutes)

1. Empty the grease tray.
2. Wipe down the exterior with a damp cloth.
3. Test every burner ignition.
4. Inspect hoses and connections.

Seasonal deep clean (30 minutes)

1. Remove the grates and flavorizer bars.
2. Scrub the grates with hot soapy water. Dry completely.
3. Vacuum out the firebox with a shop vac.
4. Clean burners with a soft brass brush. Look for clogged ports and even flame patterns.
5. Inspect venturi tubes for spider webs or insect nests — common cause of weak flame.
6. Replace any flavorizer bars that are heavily corroded.
7. Re-season cast iron grates with a thin layer of oil before storage.

Common mistakes

• Hosing down the grill. Water inside electrical components or burners causes corrosion and ignition problems.
• Skipping the cover. Uncovered storage halves grill life.
• Using oven cleaner on stainless. Most oven cleaners contain caustics that pit stainless steel.
• Wire brushes on porcelain grates. Wire brushes chip porcelain enamel and accelerate rust.

Pellet grill specifics

After every 5–10 cooks, vacuum the firepot. Once per season, empty and clean the auger tube. Damp pellets are the most common pellet-grill failure mode — keep pellets dry.
