How to Clean a Pit Barrel Cooker (Drum Smoker Owner's Guide)

The Pit Barrel Cooker (PBC) sits in its own category — it’s not a vertical bullet smoker like the Weber Smokey Mountain, not an offset stick burner, not a pellet smoker. It’s a drum smoker, with charcoal at the bottom, hanging meat suspended on hooks from rebar at the top, and a sealed drum body that produces extraordinarily even cooking through convection.

The cleaning routine is correspondingly distinctive — drum smokers accumulate residue differently than other cookers.

What’s distinctive about a PBC

Vertical drum design: charcoal basket at the bottom, hanging hooks at the top, drum walls on all sides.

Meat hangs: this is the defining feature. Briskets, pork shoulders, ribs hang from rebar through hooks rather than sitting on grates. Drippings fall directly onto the charcoal, which intensifies the smoke flavor and creates the cooker’s signature character.

Charcoal-fueled: simple, reliable, no electronics.

Limited venting: PBCs run by design with restricted airflow — minimal vent at the bottom intake, no top exhaust. This produces slow, even temperatures by burning charcoal at a controlled (oxygen-limited) rate.

What this means for cleaning

Heavy creosote on the upper drum walls: more than vertical bullet smokers. The hanging design means smoke and grease coat the upper walls more heavily.

Charcoal basket fills with drippings: the charcoal basket sits below the food. Drippings burning on charcoal is a feature, not a problem — but the basket gets coated in carbonized residue over many cooks.

Hanging hooks need cleaning: the rebar across the top and the hooks that hang from it accumulate grease.

Bottom of the drum: ash plus burned-down drippings. More than other smokers.

After-cook routine (5 minutes)

1. Let the cooker cool fully (charcoal smolders for hours)
2. Remove the rebar and hanging hooks; brush them clean while still warm if possible
3. Empty ash from the bottom (and any unburned charcoal)
4. Close the lid to discourage pest intrusion

The hanging hooks are the most-frequently-cleaned component. Brush them after every cook; they accumulate grease that turns sticky and hard to remove if neglected.

Monthly routine (15-20 minutes)

Once a month during heavy use:

Empty the charcoal basket completely. Dump ash and charcoal residue. Inspect the basket for warping or holes.

Wipe the inside of the drum. The upper portion (where smoke and grease coat the walls) needs the most attention. Plastic scraper or stiff brush; don’t strip the seasoning that protects the metal.

Wash the cooking grate (PBCs come with a small grate for items that don’t hang well — sausages, chicken pieces, etc.).

Brush the hanging hooks thoroughly: hot soapy water if needed.

Clean the bottom of the drum: ash, residue, anything that’s accumulated.

Inspect the lid handle and bottom intake: should function smoothly.

Twice-a-year deep clean

In addition to monthly:

Pull every component: rebar, hooks, grate, charcoal basket, ash plate.

Wash everything in hot soapy water (PBC components handle aggressive cleaning well — porcelain coatings on parts that have them, bare metal elsewhere).

Address rust: the PBC’s exterior can develop surface rust at the welds or in the bottom intake area. Wire brush and re-paint with high-temp paint as needed.

Check the gasket (newer PBC models have a gasket between lid and drum). Replace if degraded.

Inspect the bottom intake adjustment: the slide should move freely. Clean if grease or ash is sticking it.

Run a high-heat seasoning cycle: light a chimney, dump it in, run the cooker at maximum for 30 minutes empty. Burns off residual cleaning chemicals and refreshes the seasoning.

PBC-specific issues

Charcoal basket warping: the basket sits in direct flame for long periods. Some warping is normal; severe warping (basket no longer sits flat) means replacement.

Rebar wear: the rebar accumulates carbon deposits and develops surface oxidation. Wire-brush periodically to keep the surface clean enough that hooks don’t slip.

Hook seasoning: PBC hooks develop their own seasoning over time. Don’t strip it during cleaning — just remove gummy excess and reuse.

Bottom intake adjustment binding: ash and grease can bind the bottom intake’s adjustment mechanism. Clean during the twice-a-year deep clean.

Rust on exterior: PBCs are painted (not enameled) on the exterior. Touch-up paint annually extends cosmetic life.

Why owners love the PBC

For context: the PBC has an unusually loyal following because of the cooking results — meat hung in convection produces remarkable consistency, and the burning-drippings-on-charcoal effect creates a unique smoke character.

The cooker is also unusually forgiving. The restricted airflow means temperatures are stable; the charcoal basket lasts for very long cooks; the design is hard to mess up. Beginners produce great results with a PBC.

Cleaning is comparable to a Weber Smokey Mountain in time investment — different specifics but similar overall effort.

Lifespan

A maintained PBC typically lasts 8-12 years. Replacement parts (charcoal basket, rebar, hooks, grate) over that span run $100-200 total. The drum itself is the limiting factor — eventually rust through is possible after a decade of weather exposure.

Frequently asked questions

How is cleaning a Pit Barrel different from a Weber Smokey Mountain? +

The PBC has more residue on upper drum walls (because of hanging meat dripping onto charcoal) and different components (rebar + hooks instead of grates + water pan). Time investment is roughly equivalent; the specifics differ.

Should I oil the PBC interior? +

Yes, lightly, after deep cleaning. The natural smoke buildup over multiple cooks creates the protective seasoning, but a thin oil layer after a deep clean helps prevent rust before the next round of seasoning develops.

Can I run the PBC with the lid open? +

Generally not. The PBC is designed around restricted airflow; opening the lid exposes the charcoal to full oxygen and produces a temperature spike. Brief lid-opens for adjustments are fine; sustained open operation isn't how the cooker is designed.

How often do the hanging hooks need replacement? +

Stock PBC hooks last several years. Replacement is cheap; some owners upgrade to stainless aftermarket hooks that last indefinitely. Either approach works.

Why does my PBC produce thicker smoke than my pellet smoker? +

The drippings-on-charcoal effect. As fat drips from hanging meat onto burning charcoal, it vaporizes into thick smoke that gives the PBC its characteristic flavor. This is by design — different from pellet smoker smoke that comes only from burning pellets.
