Dirty grills aren’t just gross. They can affect your pellet grill or smoker’s temperature accuracy, fire safety, and overall performance. Your food deserves better. Here’s how to clean and maintain your pellet grill for brag-worthy results.
Why Regular Cleaning Matters
Your pellet grill needs to be taken care of in order to work at its best. Why’s it so important? Accumulated grease, rust, ash, and debris can interfere with every component like:
-
Blocking hardwood pellets from getting into the firebox from the hopper
-
Keeping the fire from properly heating the grill grates
-
Leaking smoke and heat from the pellet grill that can delay your cook
-
Trapping debris that can create a fire hazard
Those are just a few potential issues. . Not cool. Take the time to clean and maintain your pellet grill. You’ll thank yourself later.
Ash Management
Regular ash removal keeps your pellet grill or smoker running safely and cleanly.
Inspect your hopper and cooking chamber after every cook. Do yourself a solid and empty it if there’s a heavy ash buildup. If your model has a removable ash tray, empty that too.
Keeping your grill squeaky clean is a cinch with the Pit Boss Pellet Grill 5-Piece Cleaning Kit. It packs a Pit Boss chimney/burn pot scrubber, ash broom with pan and scraper, and a set of thick rubber cleaning gloves. Plus, you can store the brushes on your grill's tool hooks and keep your supplies within reach.
You can also use a wet/dry shop vacuum or dedicated ash vacuum. Avoid using a shop-vac attachment, as your regular vacuum cleaner isn’t designed to pick up fine ash. The plastic hoses and filters can even spark a fire. Better safe than sorry.
Grease and Grime Removal

Grease and grime can really do a number to your food’s flavor. After all, you don’t want to cook dinner on top of whatever you cooked a month ago. So scrape your grill grates after every cook with our Nylon BBQ Cleaning Brush.
Every 15-20 hours, it’s time for a deeper clean. Fortunately, it’s easy. Simply spray the pellet grill using the Grill & Smoker Foaming Degreaser, then wipe it off using a brush or cloth. That’s it. Make sure to clean everything in the interior, including the grill grates and drip tray. Your pellet grill will look nicer and your food will taste better. Win-win.
Gasket Care
A gasket seal keeps smoke and heat where it belongs: in the pellet grill. Some gasket leaks are easy to spot by the escaping smoke, but others are sneaky.
If your grill has a gasket, you can easily check whether or not it has a leak. Dust the edges of the lid or hopper with flour. Heat up the grill to around 250°F. Any leaking smoke will burn off the flour.
Once you have found the leak, it’s time to replace the gasket. Just remove the old seal, clean the surface, and apply the new gasket. Easy as that.
Pro tip: There’s a common misconception that gaskets need to be as tight as possible to seal properly. Not true. Just make sure it’s attached firmly, and you’ll be fine.
Temperature Probe Maintenance
Ash management, grease and grime, and gasket care take up the lion’s share of grill maintenance, but don’t forget your temperature probes. To ensure accurate temp readings and avoid cross contamination between different foods, wipe down your probes after every use with a warm soapy paper towel.
While temperature probes don’t have expiration dates, a good rule of thumb is to replace them every 2-3 years. Think your probe might be off? Test it in either boiling water (212°F) or an ice bath (32°F) by placing the probe about halfway into the water. If the temp is off by more than 15°F, it’s time to replace it.
