How to Clean a Grill Grease Trap (And All the Grease Underneath)

A grill's grease trap (also called grease tray, drip pan, or grease cup) is the single biggest source of flare-ups, smoke, mold, and grill fires. Most owners ignore it for years — until smoke pours from the bottom, a fire starts, or their Traeger displays "Clean Grease Trap." This guide covers the 6 cleaning procedures you'll actually need: routine grease trap empty/clean, deep clean for caked-on grease, full grill grease cleanup, post-grease-fire restoration, brand-specific grease trap locations (Weber, Traeger, Char-Broil, Blackstone, Nexgrill, Ninja Foodi), and how to remove grease stains from concrete or wood deck.

Empty after every 2-3 cooks; deep-clean every 5-10 cooks.

Traeger Alert · Fix It Now

Traeger says "Clean Grease Trap"? Here's what to do

Traeger grills running newer D2 controllers display a "Clean Grease Trap" reminder every 20-30 cooks. This is NOT an error — it's a scheduled maintenance prompt. The grill will still operate. But ignoring it eventually causes the HEr (high temp) error, grease fires, and warranty issues.

  1. 1

    Press the SETTINGS or MENU button on your Traeger controller.

  2. 2

    Navigate to "Reminders" or "Maintenance" — exact path varies by controller (Pro D2, Ironwood, Timberline).

  3. 3

    The alert can be dismissed AFTER you've cleaned the trap — but don't dismiss it BEFORE cleaning, or you'll forget.

  4. 4

    Follow the grease tray cleaning procedure below (Routine section of this guide).

Routine · 10 min

How to clean your grease trap (routine procedure)

Do this every 2-3 cooks. It takes 10 minutes total, prevents 90% of grease problems, and is the single most important grill maintenance task.

Grill grease tray being slid out from underneath the grill cabinet
  1. 1

    Let the grill cool fully — minimum 30 minutes after the last cook, ideally several hours.

  2. 2

    Locate the grease tray (see brand-specific section below if you can't find it).

  3. 3

    Slide the grease tray out — most slide from front, side, or rear.

  4. 4

    Empty solid debris and used grease into a SEALED trash bag (loose grease in trash bags leaks and attracts animals).

  5. 5

    Scrape any caked grease with a plastic scraper or putty knife — don't use sharp metal that can damage the tray's coating.

  6. 6

    Wash the tray with hot soapy water and a degreaser like Simple Green, Dawn Power Wash, or a dedicated grill cleaner.

  7. 7

    Rinse and dry thoroughly with a microfiber cloth — water residue accelerates rust on metal trays.

  8. 8

    Optional but recommended: install a disposable aluminum foil grease tray liner before reinstalling. Replace the liner every 3-4 cooks; the tray underneath stays clean.

Deep Clean · 30 min

How to clean a grease tray with caked-on grease

If routine cleaning has been skipped for months (or years), the grease tray will have hardened deposits that scraping alone won't remove. This procedure handles them.

Grease tray with severely caked-on grease deposits before deep cleaning
  1. 1

    Remove the grease tray as in routine cleaning.

  2. 2

    Scrape off everything you can with a plastic scraper — get the loose chunks first.

  3. 3

    Fill the tray with hot water and add 1 cup of dish soap + 2 tablespoons of baking soda.

  4. 4

    Soak for 30-45 minutes — the alkalinity breaks down hardened grease.

  5. 5

    Scrub with a stiff brush or scouring pad (steel wool on stainless trays only — never on porcelain or coated trays).

  6. 6

    For grease that still won't come off: spray with degreaser (Easy-Off Heavy Duty BBQ Grill Cleaner, Goo Gone Grill & Grate Cleaner, or Zep) and let sit for 10 minutes before re-scrubbing.

Whole-Grill · 1 hour

How to clean grease from the bottom of your grill

When grease has overflowed past the tray or accumulated INSIDE the cookbox (the bottom of the grill housing), you need a more aggressive procedure. This is where you tackle the broader "how to clean grease from a grill" cluster.

Inside of a gas grill cookbox showing grease buildup before cleaning
  1. 1

    Turn off and disconnect the propane tank (or shut off natural gas at the valve).

  2. 2

    Let the grill cool completely.

  3. 3

    Remove cooking grates, flavorizer bars/heat plates, and burner tubes.

  4. 4

    Scrape out solid grease and debris from the bottom of the cookbox with a putty knife.

  5. 5

    Vacuum loose debris with a shop vac (NOT a household vacuum — grease and ash will destroy household vacs).

  6. 6

    Spray cookbox interior with degreaser and let sit 10 minutes.

  7. 7

    Scrub with stiff brush, rinse with a garden hose if outdoor — or wipe with hot soapy rags if you can't rinse.

  8. 8

    Dry thoroughly, then reinstall components in reverse order. First cook on HIGH for 15 minutes burns off any cleaner residue.

Post-Fire · Recovery

How to clean a grill after a grease fire

A grease fire scorches, melts, and contaminates parts of the grill beyond what routine cleaning addresses. The procedure below restores the grill — but only if no structural damage occurred. If the fire warped the lid, melted control knobs, or damaged the regulator, repair-or-replace decisions come first.

Grill interior showing post-grease-fire damage requiring deep cleaning
  1. 1

    Wait until the grill is COMPLETELY cool — minimum 2 hours after the fire was extinguished. Embers can hide in grease and reignite.

  2. 2

    Inspect for structural damage: warped lid (won't close properly), melted control knobs, melted regulator hose, cracked porcelain on grates or flavorizer bars. Any of these need replacement before further use.

  3. 3

    Remove ALL components — grates, flavorizer bars, burner tubes, heat plates. Dispose of any that are clearly damaged.

  4. 4

    The cookbox interior will have heavy carbon deposits and melted grease. Scrape what you can, then spray with degreaser and let sit 20-30 minutes.

  5. 5

    Wash all reusable components with hot soapy water + degreaser. Pay special attention to the underside of the lid — soot from the fire accumulates there.

  6. 6

    Inspect the regulator hose for melted spots, cracks, or hardness. Replace immediately if damaged — see our regulator reset and replacement guide.

Surface-Specific

How to clean grease off stainless steel grill surfaces

Stainless steel grill exteriors and cookboxes pick up grease over time — especially around the lid handle, control panel, and side shelves. Wrong cleaners scratch or discolor stainless permanently. Right cleaners restore the shine.

The rule: clean WITH the grain, not across it. Stainless steel has a directional brushed finish. Scrubbing perpendicular to the grain leaves permanent scratch marks.

  • Use a stainless steel cleaner specifically (Bar Keepers Friend, Weiman Stainless Steel Cleaner, or any specific stainless-cleaning spray).
  • For baked-on grease: degreaser first (Simple Green is gentle enough), then stainless cleaner for polish.
  • For fingerprints and smudges only: microfiber cloth + glass cleaner.
  • NEVER use chlorine bleach on stainless — it pits the finish.
  • NEVER use steel wool on the visible exterior — it leaves microscratches.
  • Always wipe in the direction of the grain (usually left-to-right horizontally).

Patio Cleanup

How to remove grill grease stains from concrete or deck

Spilled grease leaves dark stains on concrete that don't wash off with normal cleaners. The fix uses absorbent materials and degreasers — and it works on fresh stains. Old stains (months+) are much harder.

Concrete

  1. Sprinkle cat litter, sawdust, or baking soda generously over the stain.
  2. Let sit overnight to absorb the grease.
  3. Sweep up the absorbent.
  4. Apply a concrete degreaser (Oil Eater, Krud Kutter Concrete Cleaner) or even dish soap and hot water.
  5. Scrub with a stiff brush, rinse with hose.
  6. For old/deep stains: a poultice (baking soda + degreaser into a paste) applied for 24 hours often works when normal cleaning doesn't.

Wood deck

  1. Same first absorption step with sawdust or cat litter.
  2. Use deck-specific cleaner (Olympic Premium Deck Cleaner, OxiClean) — degreasers can strip stain/sealant.
  3. Scrub with a soft brush only — stiff brushes raise the wood grain.
  4. Old stains may require sanding and re-staining the affected boards.

Find Your Grease Trap

Where is the grease trap on different grills?

Grease trap location varies wildly by brand and model. Here's where to look on every major grill brand.

Weber Spirit / Genesis / Summit (gas)

Weber gas grill showing grease tray slot location at the bottom rear of the cabinet

Pull from the rear bottom of the cabinet — a metal grease cup slides out on most Weber gas models. The catch pan is shaped to direct drippings into a removable cup. On older models, the entire bottom panel is the grease tray. See Weber replacement parts guide for grease cup replacements.

Weber Kettle / Performer (charcoal)

Weber charcoal kettle showing the One-Touch ash catcher under the bottom bowl

Charcoal kettles have an ash catcher (not a grease trap) under the bottom bowl. Modern One-Touch kettles have a hinged ash catcher that swings down. Clean every 2-3 cooks to maintain airflow — see our charcoal won't stay lit guide on why this matters.

Traeger Pro / Ironwood / Timberline (pellet)

Traeger pellet grill showing the grease bucket hanging from the side chute

Traegers have TWO grease management points: (1) a slanted drip tray INSIDE the grill that funnels grease to a side chute, and (2) a hanging grease bucket on the SIDE of the grill where collected grease drips into. Empty the bucket every 5-10 cooks. Replace the drip tray foil liner monthly. See Traeger replacement parts.

Char-Broil (gas)

Char-Broil gas grill grease pan sliding out from the bottom front of the cart

Most Char-Broil gas grills have a removable grease pan that slides out from the BOTTOM FRONT of the cart. TRU-Infrared models have a slightly different design — the grease catcher sits below the infrared emitter.

Blackstone Griddles (flat top)

Blackstone griddle showing the rear-mounted grease cup in its slide-in holder

Different from any other grill. Blackstone griddles have an angled cooking surface that channels drippings to either a FRONT or REAR grease cup (depending on the model). The cup slides into a holder. Empty after every cook — Blackstone griddles produce more grease than any other grill type.

Nexgrill (gas)

Nexgrill removable grease cup mounted at the bottom front of the cabinet

Most Nexgrill gas models have a removable grease cup at the bottom front. The cup is small (about 4 oz capacity) — empty after every cook.

Ninja Foodi Grill (indoor)

Ninja Foodi indoor grill grease collection chamber accessed by removing the grate

Indoor Ninja Foodi has a grease collection chamber inside the unit, accessed by removing the cooking grate and pulling out the splatter shield. Wash in the dishwasher between cooks.

George Foreman / Expert Grill

George Foreman drip tray sliding out from the front of the countertop unit

George Foreman: drip tray slides out from the front of the unit. Empty and wash after every cook — small reservoir. Expert Grill (Walmart house brand): grease cup mounted at the bottom rear, similar to Weber design. Replace the cup every 2-3 years — Expert Grill grease cups corrode faster than premium brands.

Frequency

How often should you clean your grill's grease trap?

  • Empty the grease cup/tray after every 2-3 cooks

    For routine maintenance. 5-minute job. Prevents 90% of all grease-related grill problems.

  • Deep clean the grease tray every 5-10 cooks

    Caked-on grease scrubbing. 20-30 minute job. Especially important after cooking high-fat foods (burgers, ribs, sausages).

  • Full cookbox cleanup every 25-30 cooks (or once per season)

    Whole-grill cleaning. 1-hour job. The annual maintenance most people skip — until they shouldn't have.

Myth-busting

What NOT to do when cleaning grill grease

  • Use oven cleaner (yellow can Easy-Off)

    The lye in standard oven cleaner damages porcelain coatings, etches stainless, and removes painted finishes. Use grill-specific cleaners only.

  • Rinse a hot grill with cold water

    Thermal shock can warp the cookbox or crack porcelain components. Always let the grill cool fully first.

  • Wash grease down the kitchen sink drain

    Grease solidifies in pipes and causes clogs. Pour cooled grease into a sealed container in the trash, or recycle if your municipality accepts it.

  • Burn off the grease at maximum heat

    Partially works for SURFACE grease on the cooking grates, but doesn't address grease in the tray. And running max heat on a grease-laden tray is how grease fires start.

  • Use a vacuum cleaner to suck up grease

    Household vacuums aren't rated for grease and will be destroyed. Use a shop vac, or scrape and wipe.

Safety

Cleaning safety basics

  • Disconnect propane or shut off natural gas before cleaning.
  • Wear gloves — grease cleaners are caustic.
  • Ventilate the area — degreaser fumes accumulate quickly.
  • Keep cleaners away from pets and children — many are toxic if ingested.
  • If your dog ingested any used grease (which can contain harmful bacteria) or cleaner residue (which can be toxic), call your vet immediately.

FAQ

Frequently asked questions

How often should I clean my grill grease trap?

Empty the grease cup or tray after every 2-3 cooks. Deep-clean (soak and scrub) every 5-10 cooks. Do a full cookbox cleanup every 25-30 cooks or once per season. Heavy bacon, sausage, and burger sessions fill it faster — check before every cook and empty whenever buildup exceeds half an inch.

How do I clean a grill grease trap?

Let the grill cool fully, slide the grease tray out from underneath, empty solid debris and used grease into a sealed trash bag, scrape with a plastic scraper, wash with hot soapy water and degreaser, dry thoroughly, and install a disposable foil liner before reusing. The whole job takes about 10 minutes.

Why does my Traeger say 'Clean Grease Trap'?

Traeger grills running newer D2 controllers display a 'Clean Grease Trap' reminder every 20-30 cooks. It's not an error — it's a scheduled maintenance prompt. The grill will still operate, but ignoring it eventually causes the HEr (high temp) error, grease fires, and warranty issues. Clean the trap, then dismiss the reminder via the Settings or Maintenance menu.

Where is the grease trap on a Traeger grill?

Two places. (1) Inside the grill, a slanted drip tray funnels grease through a side chute. (2) On the outside of the grill, a hanging grease bucket collects what comes out of the chute. Empty the bucket every 5-10 cooks and replace the drip tray foil liner monthly.

Where is the grease trap on a Weber grill?

On Weber Spirit, Genesis, and Summit gas grills, a metal grease cup slides out from the rear bottom of the cabinet. The catch pan above it is shaped to funnel drippings into the cup. On older models, the entire bottom panel is the grease tray. Weber kettles have an ash catcher under the bowl, not a grease trap.

Where is the grease trap on a Char-Broil grill?

Most Char-Broil gas grills have a removable grease pan that slides out from the bottom front of the cart. TRU-Infrared models place the grease catcher below the infrared emitter — slightly different access but the same slide-out design.

Where is the grease trap on a Blackstone griddle?

Blackstone griddles channel grease across the angled cooking surface to either a front or rear grease cup (depending on the model). The cup slides into a holder on the outside of the griddle. Empty after every cook — griddles produce more grease than any other grill type.

How do I clean grease from inside my grill?

Disconnect propane, let the grill cool, remove grates and flavorizer bars or heat plates, then scrape solid grease from the cookbox bottom with a putty knife. Vacuum loose debris with a shop vac (never a household vacuum), spray with degreaser, let sit 10 minutes, scrub, rinse or wipe down, and dry thoroughly. Run a 15-minute high-heat burn-off before cooking again.

How do I clean a grill after a grease fire?

Wait at least 2 hours for embers to die. Inspect for structural damage — warped lid, melted knobs, melted regulator hose, cracked porcelain. Replace damaged parts before reuse. Remove all components and scrub with degreaser. Pay attention to the underside of the lid where soot collects. Inspect the regulator hose for melted spots and replace if damaged. Have gas connections leak-tested before next use.

What's the best cleaner for grill grease?

Easy-Off Heavy Duty BBQ Grill Cleaner is the strongest grill-specific degreaser — aerosol foam that clings to vertical surfaces. Simple Green is gentler and safe on stainless steel. Goo Gone Grill & Grate Cleaner is food-safe and ideal for cooking grates and flavorizer bars. Use the right one for the surface — heavy-duty degreasers can strip painted finishes.

Can I use Simple Green to clean my grill?

Yes. Simple Green All-Purpose Cleaner is one of the safest degreasers for grills — gentle enough for stainless steel exteriors and porcelain coatings, strong enough for moderate grease buildup. Dilute per the label for routine use, or use full-strength on the grease tray. Rinse thoroughly and dry before next cook.

Can I use oven cleaner on my grill?

Only the BBQ-specific formulas like Easy-Off Heavy Duty BBQ Grill Cleaner. Standard oven cleaner (yellow can Easy-Off) contains lye that strips porcelain coatings, etches stainless, and removes painted finishes. The damage is permanent. Stick with grill-specific cleaners on grill surfaces.

How do I get grease stains off my concrete patio?

Sprinkle cat litter, sawdust, or baking soda generously over the stain and let it sit overnight to absorb the grease. Sweep up the absorbent. Apply a concrete degreaser (Oil Eater or Krud Kutter Concrete Cleaner) or dish soap and hot water, scrub with a stiff brush, and rinse with a hose. Old or deep stains may require a baking-soda-and-degreaser poultice applied for 24 hours.

How do I clean grease off stainless steel grill?

Use a stainless-specific cleaner like Bar Keepers Friend or Weiman Stainless Steel Cleaner. For baked-on grease, hit it with a degreaser like Simple Green first, then polish with the stainless cleaner. Always wipe in the direction of the grain (usually horizontal), never across it. Never use chlorine bleach (it pits stainless) or steel wool on visible exteriors (microscratches).

What's the best way to clean grease off grill grates?

Brush grates while still warm after each cook with a stainless or bristle-free brush. For deep clean, remove grates and soak in hot water plus dish soap for 30 minutes, then scrub. For caked grease, spray with Goo Gone Grill & Grate Cleaner, let sit 10 minutes, then scrub. Cast iron grates need a different process — see our rusty grill grates guide.

Can grease damage my grill?

Yes — chronically. Grease accelerates rust on cookbox bottoms and grease trays, corrodes burner tube ports from below, fuels flare-ups that warp flavorizer bars and grates, and is the #1 cause of grease fires that can damage gaskets, knobs, and regulators. A grill with a clean grease trap lasts roughly 50% longer than one that's never serviced.

Why is grease leaking out the bottom of my grill?

Three causes. (1) Grease tray is overflowing — empty it. (2) Grease cup or tray isn't seated correctly — pull it out and reseat. (3) The cookbox or grease pan has rusted through, creating holes. Hold a flashlight underneath while pouring water through to find perforations. Rust-through means part replacement, not cleaning.

Are grease tray liners worth it?

Yes — the single best ROI grill accessory. Disposable aluminum foil liners cost about $1 each, snap into the grease tray, and let you toss accumulated grease without scrubbing. Replace every 3-4 cooks. They cut grease tray cleaning time by roughly 80% and prevent rust on the metal tray underneath.

How do I dispose of used grill grease?

Let the grease cool and solidify. Scrape it into a sealed container (an empty coffee can or jar works) and put the container in the trash. Never pour grease down a sink or storm drain — it solidifies in pipes and causes clogs. Some municipalities accept used cooking grease for biodiesel recycling — check local rules.

Can I use my grill if the grease tray is full?

No. A full grease tray is the #1 cause of grease fires. The grease has nowhere to go, so the next dripping ignites instead of getting collected. Empty before every cook. If you're mid-cook and notice the tray is full, finish what's already on the grill at low heat, then clean before next use.

How do I clean a Blackstone griddle grease cup?

Slide the cup out of its holder (front or rear depending on the model), pour solidified grease into a sealed trash container, scrape any caked residue with a plastic scraper, wash with hot soapy water and degreaser, dry thoroughly, and reinstall. Empty after every cook — Blackstone produces 2-3x the grease of a typical gas grill.

What happens if I never clean my grill grease trap?

Eventually you'll have a grease fire — guaranteed, not hypothetical. Before that, you'll see persistent flare-ups even with lean cuts, smoke pouring from underneath the grill, smell of burnt grease during preheat, mold growth in warm wet weather, and accelerated rust on the tray and cookbox. Traeger grills will throw the HEr error. The fix is the same regardless: clean the trap.

Cleaner grill, fewer flare-ups

Four products cover every grease-cleaning scenario — disposable liners for daily maintenance, Easy-Off for heavy buildup, Simple Green for stainless surfaces, and Goo Gone for the cooking grates.
