Pellet grills are easy to cook on, but they’re not maintenance-free. Ash builds up in the fire pot and can stop the grill from lighting. Grease collects on the drip tray and can catch fire. Sawdust in the hopper can jam the auger.

The good news is that a little regular cleaning prevents nearly all of it. Here’s what to do and when, based on Traeger’s cleaning guidance and Smoked BBQ Source’s long-term experience.

Safety first: Always turn the grill off, unplug it and let it cool completely before cleaning. Ash can stay hot for hours, so make sure it’s cold before you vacuum it.

Pellet grill cleaning schedule

Cook a lot of fatty meats, like pork shoulder and brisket? Clean more often.

What you’ll need

• A shop vac or ash vacuum, used only for the grill
• A plastic scraper or putty knife
• A nylon grill brush
• Paper towels or rags
• A food-safe degreaser, or dish soap and vinegar
• Foil or drip tray liners and grease bucket liners
• Gloves

Traeger warns against wire brushes on its grates, and against steel wool or metal tools on drip trays, which can scratch them and cause rust. Check your grill’s manual for what it recommends.

Quick clean (every 2 to 3 cooks)

1. Make sure the grill is off, unplugged and cold.
2. Remove the grates and scrape off any stuck-on food.
3. Take out the drip tray and scrape the grease buildup into the grease chute with a plastic scraper. Replace the foil or liner.
4. Lift out the heat baffle.
5. Vacuum the fire pot and the area around and under it. Ash here is the most common reason a pellet grill won’t light.
6. Vacuum the bottom of the barrel.
7. Empty the grease bucket and replace the liner.
8. Put everything back. Make sure the fire pot sits flush and doesn’t catch on the auger tube.

This takes about 10 to 15 minutes.

Deep clean (once or twice a year)

1. Do everything in the quick clean.
2. Soak the grates, drip tray and heat baffle in hot water with a degreaser. Heavily baked-on grease may need a long soak.
3. Spray the inside of the barrel and lid with degreaser, let it sit, then wipe it off. Scrape any flaking buildup from the lid.
4. Clean the grease chute and chimney with a cloth or paper towels.
5. Empty and vacuum the hopper. Sawdust at the bottom can jam the auger.
6. Wipe the temperature probe inside the grill only if you can see buildup on it. Traeger says not to clean it otherwise.
7. Rinse and dry everything well before you put it back together.
8. Do a burn-off. Run the grill empty for about an hour to burn off any leftover cleaner and moisture.

How to prevent grease fires

Grease fires are the biggest safety risk with pellet grills. To prevent them:

• Scrape the drip tray before high-heat cooks, especially after a long, fatty smoke.
• Keep the grease chute clear and the bucket emptied.
• Use foil or liners on the drip tray and replace them often.
• If a grease fire starts, keep the lid closed and turn the grill off. Follow your manual’s instructions.

Pellet care

Pellets swell and crumble when they get damp, which can jam the auger.

• Store pellets in a sealed container in a dry place.
• Empty the hopper if the grill will sit unused for weeks, especially in humid weather.
• Use a cover and keep the grill out of rain and snow.

Still wondering?

How often should I clean my pellet grill? Empty the grease bucket and brush the grates every cook, vacuum ash every 2 to 3 cooks and deep clean once or twice a year.

Why won’t my pellet grill light? Ash in the fire pot is the most common cause. Vacuum it out. Damp pellets and an empty hopper are the next things to check.

Can I pressure wash a pellet grill? It’s not a good idea. Water can damage the electronics and soak the pellets.
