Cleaning Ash, Grease, and Gunk the Right Way

Keep your smoker in top shape with this simple maintenance guide. Learn how to clean out ash, tackle grease buildup, and avoid flavor-killing grime—without damaging your rig.

Take Care of Your Pit, and It’ll Take Care of You

A well-loved smoker is going to get dirty. Between the drips of rendered fat, piles of ash, and layers of smoke residue, it’s easy for things to build up fast. But here’s the truth: a dirty smoker doesn’t just look bad—it can mess with airflow, temperature, and even flavor.

If you want consistent cooks, clean smoke, and a smoker that lasts, regular maintenance is a must. This guide walks you through how to clean your smoker properly without overdoing it or damaging your setup.

Step 1: Let It Cool, But Not Cold

After a cook, let your smoker cool down until it’s warm but not cold. This makes grease easier to wipe off and ash easier to remove.

• Charcoal smokers: Wait 1–2 hours
• Pellet smokers: Shut down completely and wait 30–60 minutes
• Offset stick burners: Let coals burn out, then sweep out ash while still warm

Step 2: Ash Removal

Ash can retain moisture and corrode your smoker from the inside out if left too long.

How to Remove Ash:

• Use a metal ash scoop or shop vacuum (dry setting only)
• Wear gloves and a dust mask if needed
• Dump ash into a metal bin with a lid—never plastic

Pro Tip: Ash + moisture = lye, which is extremely corrosive to steel. Always keep your smoker dry and ash-free between cooks.

Step 3: Grease Trap and Drip Pan Cleaning

Excess grease can clog your smoker, cause flare-ups, or lead to nasty smoke.

What to Do:

• Remove and dump the grease tray or foil liner
• Scrape hardened grease with a plastic spatula
• Wipe with a paper towel and hot, soapy water or a degreasing spray

For pellet smokers: Make sure the grease drain channel is clear and flowing freely.

Step 4: Grates and Heat Plates

Grates don’t need to be spotless, but they should be free of chunks and buildup.

• Scrape while warm using a bristle-free brush or wooden scraper
• Soak removable grates in hot, soapy water occasionally
• Wipe heat deflectors or drip plates with a rag or degreaser every few cooks

Step 5: Clean the Inside—But Don’t Overdo It

It’s okay (and even good) to have a little smoke buildup on the interior—it helps with insulation and seasoning. But too much gunk or flaking residue? That’s a problem.

Light Interior Cleaning:

• Wipe down with a damp rag
• Scrape off peeling flakes with a plastic putty knife
• Use vinegar and water (50/50) if needed for spots

Never use soap inside your smoker—it’ll ruin your next cook’s flavor.

Step 6: Exterior Cleaning

Keep the outside looking sharp with a wipe-down using:

• Soapy water or grill cleaner spray
• Microfiber cloth or soft sponge
• Stainless steel polish (if applicable)

Dry thoroughly and cover once completely cool.
