How Experts Do Commercial Kitchen Cleaning

APBS has seen a little bit of everything in facility maintenance. Our experience has taught us one thing: every industry is different. But for restaurants and hotels? They’re in a league of their own. The standards are higher, the grease is tougher, and there’s zero room for error when a health inspector walks in.

We’ve spent years working side by side with kitchen teams, figuring out what actually works for deep cleaning. In this post, we’re sharing the practical steps and professional know-how we use every day to keep commercial kitchens running safe, clean, and inspection-ready.

Why You Need Experts to Do Commercial Kitchen Cleaning For You

An employee can simply pick up a spray bottle and wipe down a counter. But when you’re running a restaurant or hotel, the stakes are way higher. Your kitchen decides the life of your business, and if that engine isn't cleaned by people who truly know what they’re looking at, you’re leaving too much to chance.

Here is why:

Your Reputation is on the Line

Right now, the entire hospitality industry is focused on one thing: getting diners back in the seats. According to a 2025 research from the National Restaurant Association, most operators say increasing on-site traffic is critical to success. For fine dining operators, that number jumps to 90 percent, and for casual dining, it’s 87 percent.

And diners aren’t just coming for the food. 

The same research shows that the meaning of "value" has shifted; it’s about the experience. It’s the welcoming environment, genuine hospitality, and yes, unmistakable cleanliness. 

When a guest walks past the open kitchen line or uses the restroom, they are subconsciously judging your entire operation. If things look grimy or neglected, that "welcoming environment" disappears instantly. 

The "Experience Economy" Demands More

A survey of restaurant customers finds that 70 percent are interested in tasting events, 52 percent in private chef dinners, and 50 percent in on-site cooking classes. Restaurants are transforming into multi-purpose spaces for education and celebration.

Hosting a private chef dinner or a cooking class in a kitchen that hasn’t been professionally deep-cleaned? That’s a risk you don’t want to take. When you open your kitchen up as part of the "experience," it needs to be pristine. 

Safety Isn't a Guessing Game

Beyond the guest experience, there’s the reality of daily operations. Commercial kitchens are high-intensity environments. Grease builds up in hoods and ducts, creating massive fire hazards.

The Centers for Disease Control and Prevention states that facilities must be cleaned and disinfected regularly to curb the spread of disease-causing viruses and bacteria. Bacteria hide in the seals of refrigeration units. And a slip-up in cleaning can lead to cross-contamination or a failed health inspection.

Experts are trained to spot the problems you might not see. We know the codes, understand kitchen flow, and know exactly which chemicals and techniques to use on different surfaces. 

Commercial Kitchen Cleaning Checklist

Every kitchen tells a story. When we walk in after closing time, we can tell what menu items are popular, how hard the team worked that night, and, most importantly, where the cleaning tends to get pushed aside. Over the years, we've developed a rhythm. Here is how to break it down:

Cooking Surfaces

Hit these while they are still warm. It makes all the difference.

• Flattops and Grills: Use a grill brick and an acidic cleaner to break down the caramelized grease. No scratching, just smooth steel. Finish by lightly oiling the surface so it's ready for morning prep.
• Fryers: Out with the old oil. Scrub the interior walls to remove the sludge you can't see from the front. If it builds up, it burns onto your heating elements and kills your efficiency.
• Ranges: Burner grates come off and get soaked. Wipe down every knob and control panel—those spots get sticky with airborne grease and hand contact.

Countertops and Cabinets

Clear everything off. Every container, every tool. If it's sitting on the counter, it moves.

• Sanitizing: Use an EPA-approved sanitizer that kills bacteria but is safe for food contact once dry. Pay extra attention to the corners where water pools.
• Cabinets: Pull out lower racks and reach into the back corners. Crumbs and dust love to hide there.
• Touchpoints: Handles, refrigerator doors, and the underside of counter lips. These are germ magnets that casual cleaning misses.
  

Industrial Appliances

Each piece of equipment has its own personality. You have to treat them accordingly.

• Ovens: Racks come out and soak. Apply heavy-duty degreaser to the interior walls and let it sit. Be careful around heating elements and fans—damage those and you're looking at a costly repair.
• Refrigeration: Wipe down all interior shelves and drawers. Then pull the units out (if you can) and clean the condenser coils. Dusty coils make your compressor work harder, which jacks up your energy bill and leads to breakdowns.
• Ice Machines: Often forgotten. Clean and sanitize the interior bin and chute. Mold and slime love dark, wet places.
  

Floor and Walls

A clean kitchen shows in the floors. If the floors are sticky or greasy, nothing else matters.

• Sweep First: Loose debris has to go before anything wet hits the ground.
• Scrub: Use a floor cleaner designed to break down grease. Deck brush or floor machine, depending on the space. Get into grout lines and around equipment legs.
• Walls: Grease aerosolizes during cooking and settles on everything. Degrease walls from top to bottom, especially behind the cooking line. It changes how the whole kitchen smells.
  

Vents

This is where professionals separate themselves from amateurs. It's also the biggest safety factor.

• Filters: Every single one comes down. They go into a heated dip tank to dissolve the heavy grease. No shortcuts.
• Hood Interior: While filters soak, get inside the hood itself. Scraping and degreasing the walls and the fan blades.
• Ducts: Check for visible buildup where you can. A grease-clogged hood is a fire waiting to happen. Clean vents mean your exhaust system can actually do its job during service.

Waste Management and Disposal

Waste management is necessary for a truly clean and safe operation. If food debris, grease, and food residue aren’t managed properly, you’re inviting bacteria, mold, and other contaminants to take hold, putting food safety and your business reputation at risk.

You must have a comprehensive cleaning strategy that tackles every source of waste, from food particles on kitchen floors to oil and grease in deep fryers and ovens. Look closely and do regular deep cleaning routines for storage areas, cabinets, and utensil holders; food residue and greasy soils must not accumulate in hidden corners, where they can lead to costly repairs or even pest infestations.

FAQs

How much does commercial kitchen cleaning cost?

It varies based on three things: the size of your kitchen, how often you clean it, and the condition of your equipment. A small cafe pays less than a large hotel kitchen. Weekly maintenance costs less per visit than a one-time rescue clean. Most reputable companies will walk through your space before giving you a quote. If someone quotes you over the phone without seeing your kitchen, keep looking.

How do you clean a commercial kitchen?

Work top to bottom, left to right. Start with the exhaust system, end with the floors. Clear everything off surfaces so we're not just wiping around stuff. Use the right chemical for each job—degreaser for grease, sanitizer for food contact surfaces. 

Floors always go last, so any debris that fell during cleaning gets taken out the door.

What are the two main ways to sanitize?

Heat and chemicals.

Heat sanitizing uses water at least 171°F, usually in a commercial dishwasher.

Steam cleaning is an increasingly popular method that uses high-temperature vapor to kill 99.99% of bacteria without harsh chemicals.

Chemical sanitizing uses approved solutions like quats or chlorine. Let them sit wet on the surface for the time listed on the label. Spraying and wiping immediately doesn't count.

How do you deep-clean a commercial kitchen?

Deep cleaning means going beyond the daily wipe-down. Move equipment, pull out racks, and break down anything that comes apart. Filters come out and soak. 

Oven interiors get scrubbed until the carbon is gone. Get inside ice machines, behind refrigerators, and into every gap.

The exhaust hood gets special attention: ductwork, fan blades, the whole system. Walls get washed top to bottom. Floors get scrubbed deep into grout lines. 

A proper deep clean takes several hours and is usually done overnight. When it's done, the kitchen doesn't just look clean; it feels clean.

Keep Your Kitchen Running at Its Best

Besides passing inspection, a clean commercial kitchen protects your reputation, your staff, and your guests. From the exhaust hoods to the floor grout, every detail matters. 

And having experts on your side makes all the difference.
