Our score weighs specs, features and buyer feedback against what you're shopping for.

Goo Gone Grill and Grate Cleaner Spray: Best for baked-on smoker grease

9.7/10Our score

• 2-pack
• 24 oz
• Biodegradable gel
• Works on pellet and electric smokers

A strong gel for caked-on food, baked-on deposits, carbon and grease. It works on cooking grates and racks, pellet smokers and electric smokers, but not aluminum or faux stainless steel.

See it on Amazon

Pros

• Targets baked-on residue
• Works on pellet and electric smokers
• Biodegradable gel

Cons

• Not for aluminum or faux stainless steel
• Requires rinsing and drying

Goo Gone is the strongest overall choice when a smoker has caked-on food, baked-on deposits, carbon and grease. Its super-strength gel is designed for cooking grates, racks and drip pans, and it works with pellet and electric smokers.

The 2-pack contains 24 oz of cleaner. Goo Gone says the biodegradable gel can reduce smoke and flare-ups, which makes it useful when residue has built up around cooking areas.

Use it by removing the grate, spraying the foam cleaner, waiting 2 to 10 minutes, then wiping or scrubbing. Rinse and dry the surface before cooking again.

The main limit is surface compatibility. Do not use it on aluminum or faux stainless steel, even though it works on approved metal surfaces and grill interiors and exteriors.

Buy it if your main problem is baked-on smoker grease. Choose another cleaner if your smoker has aluminum or faux stainless steel parts that need treatment.

Citrusafe BBQ Grill Cleaner Spray for Outdoor: Best for cool-smoker cleaning

9.6/10Our score

• 16 fl oz
• Citrus-based d-limonene formula
• Non-flammable and phosphate free
• For cool surfaces

A citrus-based spray for buyers who clean only after the smoker is cool. It is non-flammable, non-corrosive, non-toxic and phosphate free.

See it on Amazon

Pros

• Designed for cool surfaces
• Citrus-based degreasing
• Works with grates and smokers

Cons

• Needs a separate scrubber or brush
• Must be wiped clean after use

Citrusafe is the best fit for a cool-smoker cleaning routine. Its 16 fl oz spray uses citrus-based d-limonene to cut grease on grates, racks, pellet grills, ovens, flat-top grills and electric smokers.

That cool-only approach suits people who clean after a cook has finished and the smoker has fully cooled. It avoids cleaning a hot surface and fits a routine built around patience rather than heat.

The formula is non-flammable, non-corrosive, non-toxic and phosphate free. Citrusafe also identifies ceramic as a recommended surface, but you should still confirm the surface before applying it.

Apply the spray only to a cool surface. Wait about 1 minute, scrub with a heavy-duty scrubber or non-wire brush, wipe with a damp paper towel and turn the nozzle to off before storing.

This spray needs a separate tool for stubborn residue. Pair it with the best smoker grate cleaner if the grates need more physical scrubbing.

Store the bottle with the nozzle off and keep the spray away from heat. A short wait and a firm scrub work better than soaking a hot grate.

3

Zep Heavy-Duty Oven and Grill Cleaner: Best for thick grease buildup

9.5/10Our score

• 19 oz cans
• Case of 2
• Thick foaming formula
• For stainless steel, porcelain and ceramic

A thick foam that clings to surfaces and cuts grease on stainless steel, porcelain and ceramic. It suits smokers with hard deposits across grates, pans and interior surfaces.

See it on Amazon

Pros

• Foam clings to surfaces
• Works on several hard surfaces
• Case of 2

Cons

• A stronger choice than light cleanup requires
• Needs careful surface matching

Zep is the better choice for thick grease across several hard surfaces. Its 19 oz cans come as a case of 2, and the foaming formula clings while it cuts grease on contact.

The cleaner works on stainless steel, porcelain and ceramic. It is also intended for grills, grates, pots, pans, rotisseries and burner drip pans, so it suits a smoker with more than one greasy area.

The thick foam can stay in place longer than a thin spray, which helps when deposits are vertical or spread across a drip pan. Rinse the treated area fully before using the smoker.

Zep is stronger than you need for a light wipe-down. Match it to a smoker that has firm grease buildup and confirm the surface before use.

A case of 2 suits households that clean often or share the cleaner across several outdoor cookers. Keep the second can sealed until the first is empty.

Check for overspray on nearby painted or soft surfaces before you begin. Wearing gloves and eye protection is a sensible habit with a heavy-duty grease cutter.

4

CARON & DOUCET: Best for plant-based grill care

9.2/10Our score

• 8 fl oz
• 100% plant-based and vegan
• Refined coconut oil
• Natural citrus essential oils

A coconut-oil cleaner for routine grease and residue removal. It also cleans and polishes stainless steel and plastic while building a natural seasoning on the grill.

See it on Amazon

Pros

• Plant-based and vegan
• Light citrus scent
• Useful for routine care

Cons

• Smaller 8 fl oz bottle
• Less suited to severe carbon buildup

CARON & DOUCET is the best pick for routine care and a plant-based formula. Its 8 fl oz liquid uses refined coconut oil and natural citrus essential oils.

The oil removes accumulated grease and residue, helps prevent food from sticking and builds a natural seasoning on the grill. It also cleans and polishes stainless steel and plastic.

This is a better match for regular maintenance than thick carbon deposits. Use it with wooden scrapers, brushes, tools and accessories when you want cleaning and surface care in one step.

The 8 fl oz bottle is smaller than the large-format degreasers here. Choose it when a lighter routine cleaner matters more than maximum soaking power.

A small bottle also suits a compact grill or a smoker that gets light use. The light citrus scent is designed not to transfer onto food.

Apply a modest amount and wipe with a clean cloth rather than flooding the surface. This oil works best as part of frequent care, not as a rescue cleaner.

5

Pit Boss 67290 Smoker Cleaner Grill Tool: Best for regular deep cleaning

9.0/10Our score

• For stainless steel and enameled surfaces
• Works inside and outside
• For grills, smokers, ovens and microwaves
• Use every 9 to 10 grilling sessions

A deep-cleaning formula for smoke stains, charred debris, burnt-on residue and grease. Pit Boss recommends regular use every 9 to 10 grilling sessions.

See it on Amazon

Pros

• Made for smoker and grill surfaces
• Handles smoke stains and char
• Useful inside and outside

Cons

• Surface limits still matter
• Best used as part of a cleaning routine

Pit Boss 67290 is best for scheduled deep cleaning of stainless steel and enameled smoker surfaces. Its formula targets tough grease, burnt-on residue, smoke stains and charred debris.

It works inside and outside on grills, smokers, ovens and microwaves. Pit Boss recommends regular use every 9 to 10 grilling sessions, giving you a simple starting point for a cleaning schedule.

The 67290 model measures 3 x 3 x 10.5 in. Use it when a smoker needs more than a quick grate wipe, especially after repeated cooks leave smoke stains and char behind.

The product still depends on correct surface matching and complete removal before cooking. It is a practical maintenance pick, not a substitute for checking your smoker's materials.

Counting sessions helps you avoid waiting until smoke stains become fixed. A regular interval also makes it easier to notice early grease film on the lid and interior.

Use it on a cool surface and rinse or wipe away loosened residue fully. Let the area dry before the next cook so food does not pick up cleaner.

6

GRILLART Grill Brush: Best for hot grate scrubbing

8.8/10Our score

• 18 in handle
• Stainless steel brush
• Scraper included
• For metal and porcelain surfaces

A long-handled brush and scraper for physical removal of residue from hot grates. Its 18 in handle keeps hands farther from heat, but the grates should be wiped with a damp cloth after brushing.

See it on Amazon

Pros

• Long handle
• Scraper for stubborn residue
• Works on metal and porcelain

Cons

• Wire bristles require inspection
• Not a chemical degreaser

GRILLART is the best choice for scrubbing hot grates without reaching into the cooker. Compare more BBQ grill brushes if you want a physical cleaning tool.

Its 18 in handle gives you more distance from heat, while the stainless steel brush and scraper work on metal and porcelain surfaces.

The scraper helps lift stubborn residue before the brush tackles smaller deposits. GRILLART recommends preheating the grill, soaking the brush in water, brushing in the direction of the grille and wiping the surface with a wet rag.

Because this is a wire brush, inspection matters. The directions call for wiping the grates after cleaning so loose bristles do not remain, and worn brushes should be replaced.

Choose GRILLART when you prefer physical scrubbing and want a long handle. Pick a bristle-free tool if loose wire is your main concern.

The hanging ring on the handle helps with storage between cooks. Keep the brush dry when not in use and check the bristles often for bending or loss.

7

Quality Chemical Eliminator Oven & Grill Cleaner: Best for large cleaning jobs

8.7/10Our score

• 1 gallon
• Ready-to-use degreaser
• 5 to 10 minute soak
• Can dilute 1 to 1 for light soil

A large-format degreaser for frequent or wide-area cleaning. Use it full strength for heavy soil or dilute it 1 to 1 with water for light-duty work.

See it on Amazon

Pros

• Large 128 fl oz container
• Ready to use
• Flexible dilution for light soil

Cons

• Not for aluminum, copper or painted surfaces
• Requires a 5 to 10 minute soak

Quality Chemical Eliminator is best for large smoker cleaning jobs because the container holds 1 gallon, or 128 fl oz. It is ready to use on BBQ grills, grates, ovens, broilers, hoods, stoves and fryers.

Apply it by spray or brush and let it soak for 5 to 10 minutes before wiping and rinsing. For light soil, dilute it 1 to 1 with water.

Use it full strength for heavier soil.

The large container makes sense for frequent cleaning or several greasy surfaces. It is less convenient when you only need a small bottle for occasional grate care.

Do not use it on aluminum, copper, galvanized metal, plastic tile or painted surfaces. Keep it away from children and never mix it with other chemicals.

The gallon size also suits a household that cleans a smoker, a hood and a stove in one session. Label any diluted mix clearly so it is not confused with full-strength product.

Pour only what you need into a spray bottle for smaller jobs. Rinse tools and hands after use and store the container upright in a cool place.

8

Bristle Free Grill Brush for Outdoor Grill: Best for bristle-free scrubbing

8.5/10Our score

• 16.37 in length
• Bristle-free design
• Steam cleaning
• Handle, holder, scraper, user guide and wand included

A bristle-free brush with a scraper and steam-cleaning approach for metal grill surfaces. The replaceable head and dishwasher-safe sponge support repeated cleanup.

See it on Amazon

Pros

• No wire bristles
• Scraper reaches grate sides
• Replaceable head

Cons

• Designed for metal surfaces
• Needs water for steam cleaning

The Bristle Free Grill Brush is the best fit for buyers who want to avoid wire bristles. It uses a steam-cleaning approach with a scraper, sponge and bristle-free design for metal grill surfaces.

The 16.37 in tool includes a handle, holder, scraper, user guide and wand. Its polypropylene and stainless steel construction includes a replaceable head, while the sponge can go in the dishwasher.

Use water with the steam-cleaning method, then use the scraper to lift residue from the tops and sides of grates. The tool is designed for metal, so check your smoker's surface before using it.

This is a physical cleaning tool rather than a chemical degreaser. Choose it when bristle-free scrubbing is more important than using a spray alone.

The replaceable head matters because a worn sponge will scrub less well over time. Keeping a spare on hand avoids a gap between cooks.

The hanging loop makes storage simple on a hook or rail. Rinse the head after use and let it dry before putting the tool away.

Bryson Brothers Citrusafe Complete Grill Cleaning Kit: Best all-in-one smoker kit

8.2/10Our score

• 16 oz cleaner spray
• 3-pack scrubber
• Nylon brush
• Cookbox scraper and microfiber towel

A complete set for cool-grill cleaning that combines citrus spray with scrubbers, a nylon brush, a cookbox scraper and a microfiber towel. It suits buyers starting from scratch.

See it on Amazon

Pros

• Cleaner and tools in one kit
• Nylon brush avoids wire bristles
• Includes microfiber towel

Cons

• Lower score for severe buildup
• Tools are tied to a cool-cleaning method

The Bryson Brothers Citrusafe Complete Grill Cleaning Kit is best for starting a smoker-care setup from scratch. It combines a 16 oz CitruSafe spray with 3 scrubbers, a nylon brush, a cookbox scraper and a microfiber towel.

The scrubbers and nylon brush are designed to work with CitruSafe on a cool grill. The cookbox scraper reaches tight areas and lifts burnt-on grease, while the towel wipes and polishes surfaces.

Having the spray and tools together makes the kit easier to plan than buying each item separately. It also avoids relying on a wire brush for every cleaning task.

The kit is less suited to severe buildup that needs a heavy-duty foam or gel. Choose Goo Gone or Zep when grease and carbon have hardened across large areas.

The 3 scrubbers mean you can rotate pads as they wear instead of stopping mid-clean. Wash the towel separately so grease does not spread to other cloths.

This kit suits a new smoker owner who wants one purchase instead of several small ones. It also fits as a gift for someone who cooks often but has not bought dedicated tools.

How do you choose a cleaner for BBQ smoker surfaces?

Choose a BBQ smoker cleaner by matching the formula to the residue and the surface. A gel or foam suits baked-on grease, a citrus spray suits cool cleaning, and a brush or scraper helps remove material that cleaner alone cannot lift.

Start with the surface you can see and the surface you cannot. Grates and racks are easy to identify, but drip pans, interior walls and trim can use different materials.

For stainless steel and enameled surfaces, Pit Boss is a direct fit. Zep covers stainless steel, porcelain and ceramic, while Quality Chemical works on stainless steel but excludes aluminum, copper, galvanized metal, plastic tile and painted surfaces.

Surface limits matter more than the cleaner's strength. Goo Gone excludes aluminum and faux stainless steel, so identify those parts before spraying.

Citrusafe is built for cool surfaces and needs a scrubber for stubborn residue. CARON & DOUCET suits routine care on grills, stainless steel and plastic rather than heavy carbon.

A brush or scraper should match the grate shape as well as the material. Aggressive scrubbing on a coated surface can cause damage that a gentler tool would avoid.

Think about how often you cook and how much residue you expect. A frequent cook may use a larger container, while an occasional cook may prefer a smaller spray.

Also consider whether cleaning happens soon after a cook or days later. Dried residue often needs more contact time or more physical action than fresh grease.

Read the directions for temperature, wait time and rinsing before you open the bottle. Skipping the rinse step can leave residue that affects flavor on the next cook.

Keep a simple routine that you will actually follow after each session. A quick wipe most of the time plus a deeper clean when needed works better than rare heavy effort.

Is a smoker cleaner or brush better for grease?

A cleaner is better for softening grease, while a brush or scraper is better for lifting hardened residue. The most useful setup often combines both, with the cleaner matched to the surface and the tool matched to the grate.

Chemical cleaners work by loosening grease so it can be wiped or rinsed away. They are useful on drip pans and interior walls where a brush may not reach well.

A brush works by physical contact and can remove carbon that has dried hard. That action is helpful on grates, but it can also miss grease spread across a flat surface.

Use Citrusafe with a scrubber for cool-surface cleaning. Use GRILLART when a hot grate needs physical scrubbing, or choose the Bristle Free Grill Brush when you want a tool without wire bristles.

A nylon brush fits the cool-cleaning method of the Citrusafe kit. It avoids wire bristles while still giving you a tool for corners and grate bars.

For thick grease, a foam or gel can cling during its wait time. That contact time matters more than scrubbing harder right away.

For light film, a plant-based oil cleaner can handle routine care. It also helps with polishing stainless steel and plastic around the cooker.

Consider the shape of your smoker when you choose a tool. A long handle helps on a deep cookbox, while a scraper helps along edges and corners.

Do not use a brush as a substitute for rinsing after a chemical cleaner. Loosened grease and cleaner residue should be wiped away before the next cook.

How should you clean a BBQ smoker?

Start by removing loose food and ash, then follow the cleaner's temperature and contact-time directions. Rinse treated cooking surfaces, wipe away residue and let them dry before the next cook.

Citrusafe must be used on a cool surface and needs about 1 minute to work. Goo Gone needs 2 to 10 minutes, while Quality Chemical calls for a 5 to 10 minute soak.

Use a separate cloth after brushing. GRILLART specifically calls for wiping grates with a damp cloth, and the Bristle Free Grill Brush provides a sponge-based alternative for metal surfaces.

Work on one area at a time so the cleaner does not dry before you scrub. That habit helps on large cookboxes and wide flat tops.

Never mix cleaners. Keep chemicals away from children, and avoid applying a product to a surface it excludes.

Check gloves, eye protection and ventilation before you spray. Outdoor cleaning usually provides airflow, but a closed garage or shed may not.

After cleaning, inspect grates in good light for residue or loose brush material. A final wipe with a clean damp cloth gives you a simple way to confirm the surface is ready.

Which cleaner is best for heavy smoker buildup?

Zep is the best match for thick grease on stainless steel, porcelain and ceramic, while Goo Gone is the stronger choice for baked-on food, carbon and grease on its approved surfaces. Quality Chemical is useful when you need 1 gallon for a large job.

Pick Goo Gone for a 24 oz biodegradable gel in a 2-pack. Choose Zep when thick foam that clings to surfaces is more useful, or select Quality Chemical when a 128 fl oz container and adjustable dilution matter.

For stainless steel care, see the best stainless steel grill cleaner. If grease has spread beyond the smoker, our best heavy duty grill degreaser guide covers larger cleanup tasks.

Which cleaner is best for cooking surfaces?

CARON & DOUCET is the best fit for routine cooking-surface care when you want a plant-based, vegan liquid made with refined coconut oil and citrus essential oils. Citrusafe is the better fit for a citrus spray used on a cool surface.

Use CARON & DOUCET on grills, grates, stainless steel and plastic. It is designed to remove grease and residue while building a natural seasoning on the grill.

The coconut oil approach treats cleaning and surface care as one step. That makes it useful between cooks when the residue is still light.

Citrusafe takes a different path with citrus-based d-limonene and cool-surface use. It needs a scrubber or non-wire brush for stronger scrubbing.

Choose the oil cleaner when you want light scent and regular maintenance. Choose the citrus spray when you prefer a spray format and a short wait time.

Neither option replaces a heavy-duty foam or gel for severe carbon. Thick deposits may need a stronger product matched to the surface.

For a food-prep surface that needs a stronger degreaser, compare the best food safe degreaser for grill guide and follow each product's surface directions.

Rinse or wipe cooking surfaces as the directions require before cooking again. Let plastic and stainless steel dry fully so residue does not build up in corners.

Store plant-based oils away from direct heat and keep the cap closed. A cool storage spot helps the oil stay in good shape for routine use.

Final verdict on the best cleaner for BBQ smoker

The best cleaner for BBQ smoker grease is Goo Gone Grill and Grate Cleaner Spray if your smoker has baked-on food, carbon and grease on approved surfaces. Pick Citrusafe for cool cleaning, Zep for thick foam on hard surfaces, and Pit Boss for a regular deep-cleaning schedule.

Choose GRILLART or the Bristle Free Grill Brush when scrubbing matters more than spraying. For a complete starter setup, the Bryson Brothers kit includes cleaner, scrubbers, a nylon brush, scraper and towel.

Match the pick to your surface before you match it to your budget. Aluminum, faux stainless steel, painted panels and coated areas can rule out an otherwise good cleaner.

Match the method to your routine as well. Cool cleaning suits a smoker that is left to cool, while hot scrubbing suits a cooker that is cleaned right after use.

For routine care, the plant-based oil cleaner keeps light residue from building up. For large jobs, the gallon degreaser covers several surfaces in one session.

A simple schedule helps more than a shelf full of products. Wipe grates after cooking, deep clean when grease builds and always rinse or wipe before the next use.

Frequently asked questions

What is the best cleaner for BBQ smoker grease?

Goo Gone Grill and Grate Cleaner Spray is the strongest fit here for BBQ smoker grease because its super-strength gel targets grease, baked-on food, carbon and caked-on deposits. For a cool smoker, Citrusafe is a useful citrus-based alternative.

Can you use grill cleaner inside a smoker?

Yes, but match the cleaner to the smoker's surface and follow its directions. Goo Gone works on approved metals, grates, racks and drip pans, while Zep is made for stainless steel, porcelain and ceramic.

Do not use products on surfaces they exclude.

Should a smoker be hot or cold when cleaning?

Citrusafe is made for cool surfaces, and its directions call for applying it only to a cool grill. A brush such as GRILLART is designed for hot grate scrubbing, but wipe the grates with a damp cloth afterward and inspect for loose bristles.

What removes baked-on residue from a BBQ smoker?

A thick foam or super-strength gel paired with a suitable scrubber works best for baked-on residue. Goo Gone targets baked-on deposits and carbon, while Zep uses a thick foam that clings to surfaces.

Let the cleaner sit for its stated time before wiping and rinsing.

How often should you clean a BBQ smoker?

Clean grates after cooking and deep-clean the smoker when grease, smoke stains or carbon build up. Pit Boss recommends using its cleaner every 9 to 10 grilling sessions.

Your cooking frequency and the amount of residue should guide the rest of the schedule.
