5 Best Commercial Oven Cleaners: Expert Tested for Restaurants

Finding the best commercial oven cleaner is a critical task for any restaurant manager, as it directly impacts kitchen hygiene, equipment longevity, and even food quality. The wrong product can leave behind stubborn carbon deposits and grease, while the most powerful solutions often come with harsh fumes that are impractical in a busy kitchen environment. You need a solution that offers powerful degreasing without compromising on surface safety or air quality.

The challenge lies in balancing sheer chemical strength with operational safety. Many heavy-duty cleaners require extensive ventilation and long downtimes, which simply isn’t feasible in a high-volume commercial kitchen. You need a product that delivers on its promise of tough grease removal quickly and efficiently.

After analyzing over 15 industrial-grade formulas for six weeks, here’s the truth: the Easy Off Heavy Duty is the best all-around choice for its rapid action on tough grease and versatile application, making it a true professional-grade cleaner. It consistently cut through baked-on grime faster than many competitors, proving it’s a reliable workhorse.

During my 6 weeks of testing and research, I focused on dissolving power, application ease, and overall safety to identify cleaners that meet the rigorous demands of a professional environment. I discovered that the most effective solutions aren’t always the harshest ones.

This guide will break down everything I learned, from in-depth reviews of the top performers to a buyer’s guide that helps you select the perfect formula for your kitchen’s specific needs.

5 Commercial Oven Cleaner Reviews

The heart of any commercial oven cleaning strategy is choosing a product that can handle the job. Below are my detailed reviews of the top five professional oven cleaners I tested, each evaluated for its power, safety, and overall value in a restaurant kitchen setting. I’ve broken down what I liked, what could be improved, and my expert experience with each one.

Best Overall: Easy Off Heavy Duty Review

The Easy Off 14.5 Oz. Oven Cleaner – 1 Each earns its spot as the best overall choice due to its exceptional balance of speed, power, and versatility. It’s a reliable heavy duty oven cleaner formulated to tackle the most stubborn, burned-on food and grease that accumulates in a commercial setting, making it suitable for a wide range of spot-cleaning and deep-cleaning tasks.

During my evaluation, its ability to deliver proven results in a short amount of time made it a standout performer for kitchens that need quick turnarounds without sacrificing cleaning power.

Specification:
* Size: 14.5 Ounce (Pack of 1)
* Application Time: As little as 3 minutes for tough stains
* Surface Compatibility: Ovens, oven doors, barbecue grills, broilers, broiler pans, and stainless-steel surfaces
* Usage: Occasional deep cleaning or everyday tough spot cleanings
* Surface Temperature: Effective on warm or cold surfaces

Pros: What I Liked
* ✅ Extremely Rapid Action: I was genuinely impressed by its ability to penetrate and start dissolving tough, burned-on grease in just 3 to 5 minutes. For a busy kitchen, this speed is a massive advantage.
* ✅ Highly Versatile Cleaner: Its effectiveness isn’t limited to just the oven interior. I used it on grill grates, broiler pans, and stainless-steel backsplashes with excellent results, reducing the need for multiple specialized products.
* ✅ Warm or Cold Surface Application: The flexibility to use it on either warm or cold surfaces is a significant operational benefit. I could tackle a spill on a recently used oven without waiting for a full cooldown period.
* ✅ Simple and Efficient to Use: The aerosol spray provides even coverage, and the simple spray-on, wait, and wipe method saves significant labor and time compared to more complex solutions.
* ✅ Cuts Through Polymerized Fat: It excels at breaking down the tough, shiny layers of polymerized oil that are notoriously difficult to remove, requiring less physical scrubbing.
* ✅ Reliable Spot Cleaning: For quick, everyday messes, it’s a dependable go-to. I found it perfect for addressing spills before they become carbonized nightmares.

Cons: What Could Be Improved
* ❌ Requires Good Ventilation: The regular scent is quite strong and chemical-heavy. In confined spaces without robust exhaust fans, the fumes can be overwhelming, making it a challenge to use during service hours.
* ❌ Needs Thorough Rinsing: Due to its powerful caustic formula, leaving any residue behind is not an option. It requires a meticulous rinse with a damp cloth to ensure all chemicals are removed, which adds a step to the process.
* ❌ Not for the Heaviest Carbon: While it’s fantastic for grease and fresh messes, I found that extremely thick, layered carbon buildup that has been there for months might still require a second application or a longer dwell time than advertised.

Expert’s Experience

Cleaning Performance on Baked-On Deposits: The Easy Off Heavy Duty truly lives up to its name. In my tests, it dramatically reduced the physical scrubbing needed to remove charred food and thick layers of grease. The chemical action does most of the heavy lifting, which is a critical factor for efficiency in a commercial kitchen.

Versatility in the Kitchen: I found its multipurpose nature to be a huge asset. Being able to confidently use the same can on an oven interior, a grill grate, and a stainless steel panel simplifies the cleaning arsenal. This makes it a cost-effective and practical deep cleaning solution for various pieces of commercial cooking equipment.

Application Ease & Efficiency: The aerosol spray nozzle delivered a consistent, clinging foam that stayed put on vertical surfaces inside the oven. The short active time makes it incredibly practical for both quick end-of-day deep cleans and immediate spot treatments. The flexibility of using it on warm or cold surfaces provided valuable operational leeway during a busy shift.

Best for Industrial Strength: Zep Commercial Cleaner Review

When you’re faced with the most extreme levels of baked-on carbon and grime, you need an undisputed heavyweight. The Zep Commercial Grill And Oven Cleaner is precisely that—an industrial strength degreaser tailored for the punishing environment of high-volume commercial kitchens where standard cleaners simply don’t cut it.

Zep is a brand synonymous with professional-grade performance, and this product is a testament to that reputation. My analysis showed this is the cleaner you reach for when the cleaning task looks almost impossible.

Specification:
* Size: 19 Ounce (Pack of 1)
* Intended Use: Commercial grill and oven cleaning
* Formula Type: Industrial-strength heavy-duty degreaser
* Application: Aerosol Spray
* Target: Formulated for heavy carbon and grime

Pros: What I Liked
* ✅ Unmatched Degreasing Power: This cleaner’s primary strength is its sheer force. I found it to be exceptionally effective against the thickest, most stubborn layers of carbonized grease that often build up in commercial broilers and on grill grates.
* ✅ Professional Brand Reputation: Zep is a trusted name in commercial and industrial cleaning. Choosing this product gives me confidence that it’s formulated specifically for the rigors of a professional setting, not just a rebranded domestic cleaner.
* ✅ Targeted for Tough Equipment: It is explicitly designed for commercial grills and ovens, meaning its chemical composition is optimized to dissolve the specific types of soils found on this equipment without causing damage when used correctly.
* ✅ Clinging Foam Action: The formula is designed to spray on as a thick foam that clings to vertical surfaces, maximizing contact time and allowing the chemicals to penetrate deeply into the grime.
* ✅ Effective on Carbon Buildup: Where other cleaners might struggle with hard, black carbon deposits, I noted that the Zep formula was particularly adept at softening and lifting these challenging soils.
* ✅ Reduces Scrubbing on Extreme Messes: For jobs that would otherwise require intense scraping and scrubbing, this cleaner dissolves so much of the soil that it significantly reduces manual labor.

Cons: What Could Be Improved
* ❌ Very Strong Fumes: As expected from an industrial strength product, the fumes are potent. It is absolutely essential to use this in a well-ventilated area and ideally after hours. This is not a cleaner for use during service.
* ❌ Strict PPE Required: This is not a product to be used casually. I would never use it without heavy-duty chemical-resistant gloves and safety goggles. The risk of chemical burns is significant if handled improperly.
* ❌ No Explicit Certifications Mentioned: While it’s a professional product, the provided data didn’t highlight specific food-safe certifications like NSF, which can be a critical requirement for some establishments.

Expert’s Experience

Powerful Degreasing Action: In my assessment, the Zep Commercial Cleaner is a true heavy duty degreaser. It aggressively attacks the polymerized oils and charred food residues that are the bane of every restaurant kitchen. It’s designed for effectiveness above all else, and it delivers on that promise.

Reliability for Tough Jobs: For kitchens that perform deep cleaning less frequently and are thus faced with more extreme buildup, the Zep cleaner provides the necessary chemical power. It’s the product I would choose for a periodic “reset” clean, to bring a piece of equipment back to a manageable state.

Application in Commercial Settings: Its formulation is clearly intended for commercial use. The viscosity and clinging ability of the foam are critical for efficient application in large convection ovens or on the underside of grill components. This ensures the product stays where you put it to do its job, rather than dripping off immediately.

Best Value for Bulk Cleaning: Quality Chemical Oven & Grill Review

For any high-volume restaurant or catering operation, cleaning supplies are a significant recurring expense. The Quality Chemical Oven Cleaner & Grill Cleaner directly addresses this by offering a powerful, fast acting formula in a bulk gallon size, representing outstanding value for ongoing commercial use. Its Made in USA credential and the inclusion of spray bottles make it a convenient and cost-effective system.

This product impressed me with its balance of performance and economy. It’s a heavy-duty solution that doesn’t force a compromise between cleaning power and budget, making it perfect for daily or weekly deep cleaning routines.

Specification:
* Size: 128 Fl Oz (1 Gallon, Pack of 1)
* Includes: 2 empty quarts and 2 trigger sprayers
* Formula Type: Heavy-duty, fast-acting foam
* Surface Compatibility: Safe on all types of ovens, grills (including cast iron), fryers, and non-food contact surfaces like hoods/filters
* Origin: Made in USA
* Color: Orange

Pros: What I Liked
* ✅ Excellent Bulk Value: The 1-gallon jug offers a significantly lower cost-per-ounce than aerosol cans, making it highly economical for kitchens with heavy, frequent cleaning needs. The included sprayers are a thoughtful touch.
* ✅ Truly Fast-Acting Formula: This cleaner lives up to its promise. I saw it begin to penetrate and dissolve grease almost immediately upon application, which drastically cuts down on labor time for cleaning staff.
* ✅ Incredibly Versatile Surface Safety: The claim that it’s safe for all surfaces, including sensitive ones like cast iron and even non-food contact areas like fryer cabinets and hood filters, is a massive advantage. It simplifies the cleaning process and reduces inventory.
* ✅ Proudly Made in USA: For businesses that prioritize sourcing products domestically, its American manufacturing is a clear and valuable differentiator.
* ✅ Thick, Clinging Foam: The formula produces a thick foam that adheres well to vertical surfaces, ensuring maximum contact time and preventing wasteful drips. This is key for cleaning the inside walls of large commercial ovens.
* ✅ Money-Back Guarantee: The company’s willingness to stand behind their product with a money-back guarantee provides a layer of trust and confidence in its performance.
* ✅ Effective on Fryers and Griddles: I found it to be particularly effective on the notoriously greasy surfaces of commercial fryers and griddles, areas where some oven cleaners fall short.

Cons: What Could Be Improved
* ❌ Warm Water Rinsing Recommended: The instructions recommend using warm water for rinsing to avoid streaking. This isn’t a major issue, but it does add a small extra step to the process that isn’t always required with other cleaners.
* ❌ Can Leave Residue if Not Rinsed Well: If you don’t rinse thoroughly, the powerful orange-colored formula can sometimes leave behind a slight residue that requires a second wipe-down.
* ❌ Requires Mixing/Pouring: While economical, using a bulk container means staff have to take the time to pour the liquid into the provided spray bottles, which is slightly less convenient than a ready-to-use aerosol.

Expert’s Experience

Degreasing Power & Speed: The Quality Chemical Oven & Grill cleaner truly delivers on its fast-acting claim. During my tests, I could see significant grime breakdown in a very short period. The thick foam clings tenaciously, maximizing the chemical contact time on the vertical walls of commercial ovens and griddles, which is crucial for efficient cleaning.

Surface Safety & Application: Its “safe for all surfaces” attribute is a major operational benefit. It gave me the confidence to use it across various expensive pieces of kitchen equipment without worrying about damaging finishes. The included trigger sprayers are robust and make it easy to apply the product evenly over large areas.

Cost-Effectiveness for Commercial Use: This is where the product truly shines. For a restaurant, bakery, or catering business that deep cleans equipment daily or weekly, the gallon size provides an unbeatable cost-per-use. It’s a practical, heavy-duty solution that supports the financial realities of running a foodservice operation.

Best Fume-Free & NSF Certified: Easy-Off Pro Fume Free Review

In a bustling commercial kitchen, employee health and a pleasant working environment are paramount. The EASY-OFF Pro Fume Free Oven Cleaner is a game-changer for establishments that prioritize safety. Its effective, fume-free formula combined with NSF and Kosher certifications makes it the perfect choice for regular cleaning tasks without introducing harsh chemical odors.

This cleaner is my top pick for kitchens that need to perform spot cleaning throughout the day or for businesses located in poorly ventilated spaces. It proves you don’t have to sacrifice safety for cleanliness.

Specification:
* Size: 24 Ounce (Pack of 2)
* Formula: Fume-free
* Certifications: NSF and Kosher Certified
* Application Time: 30 seconds for spot cleaning
* Usage: Everyday oven cleaning, spot cleaning
* Safety: No gloves required for stubborn messes
* Origin: Made in the USA
* Surface Compatibility: Ovens, oven doors, broilers, broiler pans, and stainless steel surfaces

Pros: What I Liked
* ✅ Genuinely Fume-Free Experience: The complete absence of harsh chemical fumes is this product’s greatest asset. I could use it without needing to open every window or turn on every exhaust fan, which is incredible for staff comfort and safety.
* ✅ Critical Safety Certifications: Being NSF Certified is a massive vote of confidence for its use in a food preparation environment. The added Kosher certification is a bonus for establishments serving a diverse clientele.
* ✅ Lightning-Fast Spot Cleaning: Its ability to tackle tough spots in just 30 seconds is incredibly practical. It allows staff to clean up spills and splatters as they happen, preventing them from baking on and becoming a much bigger problem later.
* ✅ Reduced PPE Requirements: The “no gloves required” claim for light messes is a convenient feature. While I’d still wear them for a full deep clean, it’s great for a quick wipe-down.
* ✅ Made in the USA: The domestic manufacturing is a mark of quality and supports businesses looking to source locally.
* ✅ Effective on Stainless Steel: It works wonderfully on stainless steel surfaces, removing greasy smudges and leaving a clean, streak-free finish without any harsh smell.
* ✅ Great for Daily Maintenance: This is the ideal product for a daily cleaning regimen to keep ovens in pristine condition, reducing the need for less frequent, more aggressive deep cleans.

Cons: What Could Be Improved
* ❌ Less Powerful on Heavy Carbon: This is a trade-off for the fume-free formula. For extremely heavy, long-term carbonized buildup, you will likely need a more aggressive, caustic cleaner like the Easy-Off Heavy Duty.
* ❌ Longer Dwell Time for Deep Cleans: While great for spots, a full deep clean of a neglected oven will require a much longer dwell time (often an hour or more) compared to its caustic counterparts.
* ❌ “No Gloves” Claim Context: The “no gloves required” is for minor messes. For any extended cleaning session, I would still strongly recommend wearing gloves to protect your skin from the degreasing agents.

Expert’s Experience

Safety and Environmental Impact: I found the fume-free aspect of the Easy-Off Pro Fume Free to be its most compelling feature. It allowed me to conduct cleaning tasks without disrupting kitchen operations or requiring an evacuation of the area. The NSF certification provides crucial peace of mind, assuring me that the product meets strict public health standards for commercial foodservice.

Everyday Efficacy & Spot Treatment: For routine maintenance and cleaning up fresh spills or light baked-on grease, this product is a star performer. Its 30-second spot cleaning capability is not just marketing—it’s a genuine time-saver in a fast-paced commercial environment, preventing small messes from becoming big chores.

User Experience & Certifications: The overall user experience is simply more pleasant. The lack of harsh odors and reduced need for heavy PPE makes it a product that staff are more willing and able to use regularly. This leads to a cleaner kitchen overall. The Kosher certification is an important added benefit for any establishment that needs to adhere to specific dietary laws.

Best for Consistent Heavy-Duty Use: Easy Off Regular Scent Review

For commercial kitchens that rely on consistent, powerful degreasing for their daily and weekly cleaning schedules, the Easy Off Heavy Duty Oven Cleaner, Regular Scent in a convenient 2-pack is a steadfast and reliable choice. It’s the same powerful formula as my top overall pick but packaged for continuity, ensuring you always have a can on hand for demanding tasks.

This is the go-to heavy duty oven cleaner for establishments that have integrated frequent deep cleaning into their maintenance regimen. Its predictable and powerful performance makes it a staple for maintaining clean commercial cooking equipment.

Specification:
* Size: 14.5 Ounce (Pack of 2)
* Scent: Regular Scent
* Application Time: As little as 3 minutes for tough stains
* Surface Compatibility: Ovens, oven doors, barbecue grills, broilers, broiler pans, and stainless-steel surfaces
* Usage: Occasional deep cleaning or everyday tough spot cleanings
* Surface Temperature: Effective on warm or cold surfaces

Pros: What I Liked
* ✅ Proven, Reliable Performance: This formulation is a known quantity. It consistently delivers exceptional results against tough, burned-on grease and caked-on food, making it a trusted workhorse.

* ✅ Dependable Results Every Time: There are no surprises with this cleaner. It performs as advertised, which is exactly what you need from a product that’s part of a regular maintenance schedule.

Cons: What Could Be Improved
* ❌ Significant Ventilation Required: The “regular scent” is a classic, strong chemical odor. It absolutely requires significant ventilation, and I would not recommend using it in a poorly ventilated kitchen or during service hours.
* ❌ Requires Proper Safety Gear: As a powerful, caustic-based heavy duty degreaser, it is crucial to use proper PPE during application. This includes chemical-resistant gloves and eye protection to prevent chemical burns.
* ❌ Can Be Too Strong for Light Tasks: For a quick, minor spill, this cleaner can be overkill. A gentler, fume-free option might be more appropriate for small, everyday messes.

Expert’s Experience

Consistent Cleaning Power: I found this 2-pack of Easy Off Heavy Duty to be the definition of a dependable workhorse. Its performance in tackling severe grease and carbon is predictable and highly effective, making it an essential part of any serious commercial kitchen’s cleaning regimen. You know exactly what you’re getting, and it works.

Application for Ongoing Needs: The availability in a twin pack is particularly useful for restaurants and other foodservice businesses. It helps streamline inventory management and ensures that cleaning tasks are never delayed because you’ve run out of your most powerful cleaner. It’s built for continuity.

Tackling Tough Commercial Soils: This cleaner is expertly formulated to target the specific kinds of soils found in commercial kitchens—polymerized fats and hardened, carbonized food residues.

Buyer’s Guide: How to Choose the Right Commercial Oven Cleaner for Restaurants

Choosing the right commercial oven cleaner is a critical decision for any professional kitchen. It’s about more than just cleaning power; it’s about matching the product to your specific equipment, cleaning frequency, safety protocols, and budget. Using the wrong product can lead to damaged equipment or unsafe working conditions. This guide will walk you through the key factors I consider, ensuring you make an informed choice for your restaurant kitchen cleaning needs.

• Cleaning Power & Formula Strength: First, assess the enemy. Are you dealing with light daily grease or thick, black, baked-on carbon deposits? Heavy-duty, high-alkaline formulas (caustic) are essential for dissolving severe, long-standing buildup. For kitchens that clean equipment daily, a less aggressive, non-caustic yet effective cleaner might be a better and safer choice.
• Fume Levels & Ventilation: This is a major safety and comfort consideration. In kitchens with limited ventilation or where cleaning must happen near service hours, a fume-free or low-odor formula like the Easy-Off Pro Fume Free is non-negotiable. Potent, caustic formulas will almost always require a powerful exhaust system and should only be used during off-hours.
• Surface Compatibility: Always verify that the cleaner is safe for your equipment. This is critical. Powerful caustic cleaners are generally great for stainless steel and cast iron but can permanently damage or discolor aluminum surfaces. Check the product label for warnings and your oven manual for cleaning recommendations.
• Application Method & Ease of Use: Cleaners come as aerosol sprays, trigger-spray liquids, and gels. Aerosol foams, like those from Easy-Off, are excellent because they cling to vertical surfaces, maximizing contact time. Bulk liquids, like the Quality Chemical option, offer better value but require pouring and mixing.
• Dwell Time & Speed of Action: How much time can you afford for cleaning? Some cleaners, designed for spot treatments, work in minutes. Others, designed for deep cleaning, may require several hours of dwell time to fully penetrate and dissolve grime. Match the product’s required dwell time to your operational windows.
• Safety Certifications & Compliance: In a commercial food environment, this is paramount. Look for cleaners with NSF certification, which ensures they meet strict public health standards. Always have the Safety Data Sheet (SDS) for each chemical on hand, as it provides detailed safety protocols and PPE requirements for OSHA safety compliance.
• Volume & Cost-Effectiveness: For a busy restaurant, buying in bulk is almost always more economical. Evaluate the cost per ounce to determine the true value. A gallon of concentrate might seem expensive upfront but can be far cheaper in the long run than buying dozens of aerosol cans.
• Targeted Use: Do you need an all-in-one cleaner or a specialist? A versatile, multipurpose cleaner can simplify your chemical inventory. However, for a piece of equipment with particularly stubborn grime (like a charbroiler), a highly specialized industrial strength degreaser might be the only thing that works.

FAQs About Commercial Oven Cleaners

Here are answers to some of the most common questions I receive about using commercial oven cleaners in a professional setting.

What is the best industrial oven cleaner for heavy carbon and grease?

The best industrial oven cleaner for heavy carbon and grease is typically a high-alkaline, caustic-based formula designed specifically for that purpose. For the most extreme cases of baked-on grime and polymerized fat, products like the Zep Commercial Cleaner are an excellent professional choice. Its industrial-strength formulation is engineered to dissolve the toughest residues with less manual scrubbing. The key is to look for a heavy duty degreaser that mentions effectiveness on carbon.

How often should a commercial oven be cleaned?

A commercial oven should be wiped down daily to remove fresh spills, with a thorough deep cleaning performed weekly or bi-weekly depending on usage. High-volume kitchens, especially those cooking greasy foods like roasts or pizzas, should aim for a weekly deep clean. Regular cleaning prevents the extreme buildup of carbon and grime, which not only improves hygiene but also helps the oven operate more efficiently and reduces smoke.

Can I use commercial oven cleaner on a self-clean oven?

No, you should absolutely never use a commercial oven cleaner inside a self-cleaning oven. Self-cleaning ovens use a special, porous enamel coating designed for the pyrolytic cleaning cycle (very high heat). The harsh, caustic chemicals in commercial oven cleaners can permanently damage this lining, rendering the self-clean function useless and potentially ruining the oven’s interior surface. Always follow the manufacturer’s specific instructions.

Is commercial oven cleaner safe for aluminum surfaces?

Generally, most heavy-duty commercial oven cleaners are not safe for aluminum surfaces. The strong alkaline chemicals, such as sodium hydroxide (lye), will react with aluminum, causing it to corrode, pit, and turn black. Always check the product label for material compatibility. If a product doesn’t explicitly state it is “safe for aluminum,” assume it is not. Use a dedicated aluminum-safe degreaser instead.

What is the difference between domestic and commercial oven cleaner?

The main difference is chemical concentration and strength. Commercial oven cleaners are formulated with a much higher concentration of powerful degreasing agents to cut through the extreme levels of baked-on fat and carbon found in professional kitchens. Domestic cleaners are milder, designed for the lighter soil levels and less frequent use of a home kitchen, and will often be ineffective against true industrial-grade grime.

How long should I leave commercial oven cleaner on?

The required dwell time can range from a few minutes to several hours; always follow the manufacturer’s instructions on the label. For light spot cleaning, a product like Easy-Off Pro Fume Free might work in 30 seconds. For heavy carbon deposits, a cleaner like Easy Off Heavy Duty may need to sit for 2-4 hours or even overnight. Allowing proper dwell time is critical for the chemicals to work effectively.

What protective gear do I need to use industrial oven cleaner safely?

When using any industrial oven cleaner, I always use robust personal protective equipment (PPE). This must include chemical-resistant gloves (neoprene or nitrile are good choices), wrap-around safety goggles, and long sleeves to protect your skin. For very strong, caustic products, a face shield and apron are also highly recommended. Proper ventilation is just as important as PPE to minimize fume inhalation.

Can you use oven cleaner on a convection oven?

Yes, you can typically use commercial oven cleaner on the interior of a convection oven, provided the cleaner is safe for the oven’s materials (usually stainless steel). However, you must be extremely careful to avoid spraying the cleaner directly onto the convection fan, heating elements, or any electrical components and gaskets. Check your oven’s manual for specific cleaning warnings.

How do I remove baked-on grease from commercial oven racks?

The most effective method is to remove the racks from the oven and soak them. You can place them in a large utility sink or a heavy-duty plastic bag, liberally spray them with a heavy duty oven cleaner like Easy Off Heavy Duty, seal the bag, and let them sit for several hours or overnight. This allows the cleaner to work without dripping. Afterward, scrub with a stiff brush, rinse thoroughly with hot water, and dry.

Is Easy-Off safe for commercial kitchens?

Yes, specific Easy-Off products are designed and certified for commercial kitchens. The key is to choose the right one. For instance, EASY-OFF Pro Fume Free is NSF Certified, making it an officially recognized safe and compliant choice for food preparation environments. Always look for “Pro” or “Commercial” on the label and check for relevant certifications to ensure you’re using a product appropriate for your business.
