Your Masterbuilt electric smoker has just finished its third brisket marathon, but now it’s coated in sticky grease and stubborn smoke residue that threatens your next cook. That lingering film isn’t just unsightly—it causes bitter flavors, temperature fluctuations, and even fire hazards if ignored. The good news? You can restore your smoker to factory condition using proven techniques that professional pitmasters swear by, without expensive tools or harsh chemicals. This guide delivers the exact step-by-step process for how to clean Masterbuilt electric smoker interiors, components, and grease systems—saving you hours of scrubbing while extending your smoker’s lifespan.
Unplug and Cool Down Before Touching Anything
Never skip this critical safety step: Your Masterbuilt must be completely unplugged and cooled below 115°F before cleaning begins. Vertical electric smokers trap heat in their insulated chambers, and rushing this step risks severe burns—especially near the heating element. Allow 2-3 hours for full cooling after cooking, then verify by placing your hand near (but not touching) interior surfaces. If you feel warmth, wait longer.
Once fully cooled, remove every detachable part for separate cleaning:
– All cooking racks and support brackets
– Drip deflector and water pan assembly
– Wood chip tray and loader mechanism
– Bottom grease tray
This exposes hidden residue pockets while preventing cross-contamination during cleaning.
Select Your Cleaning Solution Based on Buildup Level
Vinegar Solution for Light to Moderate Residue
For routine cleanings after 3-5 cooks, mix equal parts water and apple cider vinegar in a spray bottle. This food-safe formula dissolves smoke residue without toxic fumes or lingering odors. Shake vigorously before use, then spray liberally on interior walls, ceiling, and floor. Let it sit for 8 minutes—the acid penetrates baked-on grease while neutralizing creosote that causes bitter flavors.
Commercial Cleaners for Heavy Grease Buildup
Purple Power (Walmart) tackles extreme lard coatings from multiple briskets with minimal scrubbing. Users confirm it works “much faster than solvents” but requires thorough rinsing. Awesome Cleaner (Dollar Tree) earns top marks for “brand new” results, though its strong odor demands a follow-up vinegar spray. Greased Lightning (Home Depot) needs “very little elbow grease” but requires 3+ wipe-downs to eliminate residue. Pro tip: For window models, avoid all commercial cleaners on glass—they cause permanent etching.
Deep Clean Interior Walls Without Damaging Components

After spraying your chosen solution, wait 10 minutes to soften residue—this reduces scrubbing effort by 70%. For stubborn deposits near the heating element, use fine steel wool (000-grade) with a BBQ scraper in gentle circular motions. Critical warning: Never spray liquids directly on the control panel, heating coil, or temperature probes. For these areas, dampen a microfiber cloth with vinegar solution and wipe carefully—excess moisture causes electrical shorts.
Wipe residue into paper towels immediately; re-soil occurs if you let dissolved grease re-dry. Replace towels every 2-3 passes to avoid spreading gunk. Pay special attention to corners where grease pools—these spots accelerate rust if neglected.
Clean Removable Components Correctly
Racks and Drip Pans: Dishwasher or Hand Wash?
Check your manual first—some Masterbuilt racks are dishwasher-safe (top rack only). If hand-washing, use hot water with Dawn dish soap and a stainless steel brush. Scrub both sides thoroughly, then rinse until water runs clear to prevent soapy off-flavors. Never soak racks overnight—this accelerates rust on coated surfaces. Dry completely with a lint-free cloth before reassembly.
Wood Chip Tray Ash Removal Protocol
Dump ash residue after every cook to prevent loader clogs and flare-ups. Never use water on this component—moisture corrodes the electrical ignition system. Instead, wipe with a dry paper towel while the tray is still warm (but not hot). For stubborn ash, use a stiff-bristle brush designed for grill grates.
Grease Tray Foil Liner Hack
Line your water pan and bottom tray with heavy-duty aluminum foil before each smoke session. When finished, simply peel off the foil—no scrubbing required. This method works flawlessly for Cabela’s Sportsman Edition models (which lack cleaning access windows) and cuts cleanup time by 80%. Empty the grease tray when 75% full; overflow causes electrical shorts in the base unit.
Restore Glass Visibility on Window Models

Spray the 50/50 vinegar solution directly onto the glass door—avoid commercial cleaners that etch the surface. Gently scrub with a non-abrasive sponge (like a blue Scotch-Brite) using circular motions. Wipe dry immediately with a microfiber cloth to prevent water spots that obscure visibility during cooks. Pro tip: Apply a thin coat of cooking oil after drying—it creates a barrier that repels future smoke residue.
Re-Season Your Smoker After Cleaning
Reassemble all components only when completely dry—trapped moisture causes rust within hours. Run an empty smoke cycle for 60 minutes at 225°F with hickory chips to:
1. Burn off any residual cleaning solution
2. Re-coat interior surfaces with protective smoke seasoning
3. Verify electrical components function properly
Skipping this step invites metallic flavors in your next cook and accelerates corrosion.
Follow This Exact Cleaning Schedule
Daily Maintenance (After Every Cook)
- Empty grease tray when ¾ full
- Remove ash from wood chip tray
- Wipe exterior with vinegar solution
Every 3-5 Smokes
- Clean racks, water pan, and drip deflector
- Quick interior wipe-down if residue is visible
Deep Clean (Every 8-12 Uses)
- Full interior scrubbing cycle
- Component inspection for rust/corrosion
- Control panel electrical check
Alternative approach: Some competitive pitmasters never clean interiors, claiming seasoning buildup enhances flavor. They rely solely on foil liners for grease management—only washing racks and drip pans. This works if you smoke the same meat types consistently but risks bitter notes with poultry or fish.
Avoid These 3 Costly Cleaning Mistakes
Ash disposal errors cause fires: Always wrap cold ashes in aluminum foil, soak with water for 24 hours, and dispose in a metal container. Throwing hot ashes in plastic bins ignites garage fires—Masterbuilt service logs confirm this as the #1 preventable accident.
Electrical damage from moisture: Water contacting the control panel causes $150+ repair bills. If you accidentally splash electronics, leave the unit disassembled in a dry garage for 48 hours before plugging in.
Rust from improper drying: Leaving damp racks inside overnight creates rust spots that flake into food. Always air-dry components on a rack for 2 hours before storage.
