How to Clean a Pit Boss Pellet Grill
A Pit Boss pellet grill must move air through its burn pot while grease drains away from the cooking chamber, so ash and grease require separate cleaning methods. Pit Boss recommends routine grate care and a deeper clean after roughly 40 to 60 pounds of pellets, including vacuuming cold ash from the barrel and fire pot. This guide covers horizontal Pit Boss wood-pellet grills; vertical smokers, griddles, and combination models have different grease paths and should use their own manual.

What you will need
- The manual for the exact Pit Boss model
- Heat-resistant gloves for warm grate care
- A nylon or manufacturer-approved grill brush and scraper

- Pit Boss grill degreaser or another model-approved cleaner
- A plastic putty scraper and a small brush for the burn pot
Step-by-step instructions
Step 1: Finish shutdown and let the grill become stone cold
Run the model's normal shutdown cycle so remaining pellets in the burn pot finish safely, then switch off and unplug only after the fan stops. Let the grates, broiler plate, barrel, grease, and ash cool fully. Never vacuum warm ash; a hidden ember can ignite vacuum dust or a trash container.
Step 2: Empty the grease bucket and clean the exterior
Remove the cold grease bucket, solidify or contain grease, and dispose of it according to local rules—never down a sink. Wash or replace its liner as the manual allows. Wipe the painted or stainless exterior with a compatible cloth and cleaner, applying liquid to the cloth rather than controls, display, hopper, vents, or electrical seams.
Step 3: Brush the cooking grates
Scrape food residue with a tool suitable for the grate finish and inspect for loose bristles. Remove grates for a deeper clean only when cold. Use warm mild-soapy water if the exact grate material permits, rinse and dry immediately, and restore any seasoning required for cast iron or porcelain-coated components.
Step 4: Remove the flame broiler and grease tray
Photograph the orientation of the slider, flame-broiler plate, and grease tray before lifting them out. Scrape cold carbon and grease toward a disposable liner or pan with a plastic tool. Pit Boss-approved foaming degreaser can be used on compatible surfaces as its label directs, but it must be wiped away and kept out of the burn pot, igniter, probe connections, and hopper.
Step 5: Vacuum the barrel and burn pot
With the grill unplugged and every particle cold, vacuum loose ash from the barrel and fire pot. Pit Boss identifies this as part of the deeper service generally performed after 40 to 60 pounds of pellets. Clear air holes gently with a dry brush; do not bend the igniter rod, enlarge holes, or leave a vacuum nozzle pressing on wiring.
Step 6: Clear the grease channel and drain
Scrape accumulated grease toward the bucket opening and verify the channel is open. Do not push hard metal tools into the drain tube or smear grease into insulation. Heavy hardened deposits may need repeated approved degreaser contact on the cold metal, followed by complete wipe-off, rather than force.
Step 7: Clean the temperature probe and gasket
Wipe the internal temperature probe with a damp cloth or model-approved mild cleaner without twisting or bending it. Brush crumbs from lid gaskets and inspect for tears, flattening, or grease saturation. Do not soak electrical probes or saturate gasket adhesive. Inaccurate readings after gentle cleaning call for calibration checks or service.
Step 8: Check the hopper without adding water
Remove pellet dust with a dry vacuum only when the manual permits hopper emptying and the grill is unplugged. Never rinse the hopper, auger, or pellets. Swollen pellets can harden inside the feed system. If the auger is jammed, use Pit Boss's repair procedure rather than forcing it during cleaning.
Step 9: Reassemble and perform a supervised startup
Return the grease tray and flame broiler in their original slope and orientation, reinstall dry grates, and seat the grease bucket. Plug in and start the grill with the lid position required by the manual. Watch ignition, smoke, temperature rise, and grease flow. Shut down if pellets overflow, ignition fails, or abnormal flame appears.
