How to Clean a Commercial Kitchen
Running a commercial kitchen comes with constant pressure — tight service windows, strict food safety standards, and equipment that never really gets a break. Cleaning often gets pushed to the end of the day when everyone is tired, but in reality, it’s one of the most critical parts of operating a compliant and efficient kitchen.
Learning how to clean a commercial kitchen properly isn’t just about making it look tidy. It’s about food safety, staff safety, compliance with Australian health regulations, and protecting expensive equipment from long-term damage. A rushed or inconsistent approach can quickly lead to grease build-up, cross-contamination risks, pest issues, and failed inspections.
We break down commercial kitchen cleaning into clear, easy to follow steps. It’s written for Australian cafés, restaurants, takeaways, pubs, clubs, and institutional kitchens that need a practical, repeatable system — not theory.
Commercial Kitchen Cleaning Standards in Australia
Before getting into the “how”, it’s important to understand the expectations placed on commercial kitchens in Australia.
Food Safety and Compliance Requirements
Commercial kitchens must comply with:
-
State and local council food safety regulations
-
Food Standards Australia New Zealand (FSANZ) guidelines
-
Workplace health and safety obligations
Inspections typically focus on:
-
Cleanliness of food preparation surfaces
-
Grease and grime accumulation
-
Evidence of pest activity
-
Hygiene in hard-to-reach areas
-
Correct chemical storage and use
A visibly clean kitchen doesn’t always mean a compliant one. Inspectors look for systematic cleaning, not just surface-level results.
The Difference Between Domestic and Commercial Kitchen Cleaning
Cleaning a commercial kitchen is fundamentally different from cleaning a home kitchen.
Why Commercial Kitchens Need a Structured Approach
Commercial kitchens:
-
Operate for long hours, often 7 days a week
-
Produce higher grease loads
-
Use heavier-duty equipment
-
Have multiple staff using the same spaces
Because of this, cleaning must be:
-
Scheduled
-
Documented
-
Consistent
-
Appropriate for food-contact environments
A “clean as you go” mindset helps, but it’s not enough on its own.
Preparing to Clean a Commercial Kitchen
Good cleaning starts before any chemicals or equipment are used.
Shut Down and Make the Area Safe
Before cleaning begins:
-
Turn off cooking equipment and allow it to cool
-
Disconnect portable appliances
-
Isolate gas and electrical equipment where required
-
Remove food, utensils, and packaging from surfaces
Rushing this step often leads to burns, slips, or damaged equipment.
Gather the Right Cleaning Supplies
A commercial kitchen should have:
-
Food-safe detergents and degreasers
-
Colour-coded cloths and mop heads
-
Scrub pads suitable for stainless steel
-
Floor cleaning equipment
-
PPE such as gloves and non-slip footwear
Using incorrect chemicals is one of the most common compliance issues seen during inspections.
Step-by-Step Guide to Cleaning a Commercial Kitchen
Cleaning Food Preparation Areas
Food prep areas require the highest level of hygiene.
Benches, Cutting Boards, and Worktops
These surfaces should be cleaned:
-
Between tasks
-
After raw food preparation
-
At the end of each shift
Best practice includes:
-
Removing debris and food scraps first
-
Washing with warm water and food-safe detergent
-
Rinsing thoroughly
-
Sanitising where required
-
Allowing surfaces to air dry
Wooden boards should be assessed regularly, as they can harbour bacteria if damaged.
Cleaning Cooking Equipment
Cooking equipment is where grease builds up fastest.
Ovens, Grills, and Cooktops
These should be cleaned daily in most commercial kitchens.
Key points:
-
Remove removable parts and soak separately
-
Use appropriate degreasers designed for food environments
-
Avoid abrasive pads on stainless steel
-
Pay attention to knobs, handles, and control panels
Grease left to build up becomes harder to remove and increases fire risk.
Fryers
Fryers require special attention:
-
Oil should be filtered or replaced regularly
-
Crumbs and debris removed daily
-
Exterior surfaces degreased to prevent slip hazards
Poor fryer hygiene is a common cause of kitchen odours and pest attraction.
Cleaning Exhaust Systems and Rangehoods
This is one of the most neglected areas in commercial kitchens.
Filters, Canopies, and Ducting
Rangehood filters should be:
-
Removed and cleaned regularly
-
Degreased thoroughly
-
Completely dry before refitting
Signs exhaust cleaning is overdue:
-
Sticky residue on walls or ceilings
-
Reduced airflow
-
Strong lingering cooking smells
In many kitchens, ducting cleaning must be carried out by specialists due to access and safety requirements.
Cleaning Floors in a Commercial Kitchen
Kitchen floors are exposed to grease, spills, and foot traffic all day.
Daily Floor Cleaning
At minimum, floors should be cleaned at the end of every service day.
Steps include:
-
Sweeping or vacuuming loose debris
-
Applying a suitable degreasing floor cleaner
-
Scrubbing textured or grout-heavy surfaces
-
Rinsing thoroughly
-
Allowing floors to dry completely
Leaving detergent residue behind can make floors slippery.
Why Mopping Alone Is Often Not Enough
In busy kitchens, traditional mopping:
-
Spreads grease rather than removing it
-
Leaves residue in grout lines
-
Doesn’t clean textured anti-slip flooring effectively
Many commercial kitchens use mechanical floor scrubbing to achieve consistent results.
Cleaning Walls, Splashbacks, and Doors
Grease doesn’t stay confined to cooking equipment.
Vertical Surfaces Matter More Than You Think
Walls and splashbacks should be cleaned:
-
Daily near cooking zones
-
Weekly in lower-risk areas
Focus on:
-
Tile grout
-
Corners and joins
-
Door handles and push plates
Ignoring vertical surfaces is one of the easiest ways to fail a visual inspection.
Cleaning Refrigeration and Cold Storage Areas
Cold storage areas are often assumed to be “clean” because they’re cold — this is a mistake.
Cool Rooms and Freezers
Regular cleaning prevents:
-
Mould growth
-
Odour build-up
-
Cross-contamination
Best practice includes:
-
Removing stock and placing it in temporary cold storage
-
Cleaning shelves and seals
-
Checking drains for blockages
-
Wiping down doors and handles
Spills in cool rooms should be cleaned immediately, not left until scheduled cleans.
Cleaning Sinks, Drains, and Plumbing Fixtures
Sinks and drains are high-risk areas for bacteria.
What Inspectors Look For
Common problem areas include:
-
Food debris in sink corners
-
Slow-draining pipes
-
Build-up around drain grates
Drains should be:
-
Flushed regularly
-
Treated with appropriate cleaning products
-
Inspected for odours or blockages
Ignoring drains often leads to pest problems.
Waste Management and Bin Areas
Clean kitchens still fail inspections due to poor waste handling.
Internal and External Bin Hygiene
Bins should be:
-
Emptied daily
-
Washed and sanitised regularly
-
Kept closed when not in use
External bin areas should be:
-
Free from spills
-
Washed down regularly
-
Located away from food prep zones
Overflowing or dirty bins are a red flag for inspectors.
Creating a Commercial Kitchen Cleaning Schedule
Cleaning only works when it’s consistent.
Daily, Weekly, and Monthly Tasks
A structured schedule should include:
Daily tasks
-
Benches and prep areas
-
Cooking equipment surfaces
-
Floors
-
Bins
Weekly tasks
-
Walls and splashbacks
-
Fridge interiors
-
Shelving
Monthly tasks
-
Deep equipment cleaning
-
Exhaust systems
-
Storage areas
Written schedules help with accountability and training.
Staff Training and Accountability
Even the best cleaning plan fails without staff buy-in.
Making Cleaning Part of the Culture
Effective kitchens:
-
Train staff on correct cleaning methods
-
Use checklists
-
Assign responsibility clearly
-
Lead by example
Cleaning should never be “someone else’s job”.
Common Commercial Kitchen Cleaning Mistakes
Understanding mistakes helps avoid them.
Frequent Issues Seen in Australian Kitchens
-
Using domestic cleaning products
-
Skipping hard-to-reach areas
-
Poor chemical dilution
-
Inconsistent cleaning routines
-
Relying on visual cleanliness only
Most of these issues are easy to fix with the right systems in place.
When to Use Professional Cleaning Services
Some tasks are better handled externally.
Situations That Call for Specialists
-
Exhaust ducting cleaning
-
Heavy grease build-up
-
End-of-lease cleans
-
Post-incident deep cleans
Professional services can complement in-house cleaning, not replace it.
Final Thoughts on Cleaning a Commercial Kitchen
Knowing how to clean a commercial kitchen properly is about more than ticking a box for inspections. A clean kitchen runs more smoothly, lasts longer, and creates a safer environment for both staff and customers.
The most successful kitchens treat cleaning as part of daily operations — not an afterthought. With the right processes, products, and habits, maintaining a high standard becomes manageable rather than overwhelming.
