How to Clean Commercial Kitchen Equipment: A Complete Guide

After a Friday night service the fryer oil smells burnt, the combi oven is coated in grease and the stainless steel benches are covered in fingerprints. Every kitchen looks like this at the end of a big service. What separates a well-run kitchen from a poorly run one is what happens next.

Proper cleaning of commercial kitchen equipment protects food safety, extends equipment life, reduces energy costs and keeps you compliant with Standard 3.2.2 of the Australia New Zealand Food Standards Code. This guide covers the most common commercial kitchen equipment with step-by-step cleaning routines for each.

Why Cleaning Commercial Kitchen Equipment Matters

General Principles

A few rules apply across every piece of equipment regardless of type:

• Always switch off and isolate equipment from power before cleaning
• Use warm water with mild detergent unless the manufacturer specifies otherwise
• Rinse thoroughly to remove all chemical residue from food-contact surfaces
• Dry completely to prevent rust, mould and electrical issues
• Follow the grain when wiping stainless steel — wipe across it and you will scratch the surface
• Never mix cleaning chemicals unless confirmed compatible — certain combinations produce toxic gases
• Use protective gloves when handling commercial degreasers or descalers

Common Mistakes to Avoid

Step-by-Step: Cleaning Key Equipment

How to Clean Commercial Combi Ovens

Commercial combi ovens handle roasting, steaming, baking and reheating across a single service — which means they collect grease, carbon buildup and mineral deposits from the steam system quickly. Without consistent cleaning, the result is uneven cooking, persistent odours and higher running costs.

Daily Cleaning Routine

• Cool and prepare: Allow the oven to cool. Switch off and disconnect power.
• Remove accessories: Take out trays, racks and pans and soak in warm soapy water.
• Wipe interior: Use a manufacturer-approved oven cleaner or mild degreaser. Avoid bleach.
• Check fans, corners and door seals: Grease accumulates fastest in these areas.
• Run auto-clean if available: Many modern combi ovens include an automatic cleaning program — use it daily to save time and water.
• Dry and reassemble: Wipe with clean water, dry thoroughly and reinsert racks before next service.

Weekly Deep Clean and Descaling

• Remove buildup: Use a non-abrasive pad or scraper for burnt-on grease and carbon deposits.
• Clean glass doors: Warm water with a small amount of white vinegar removes grease and streaks from the interior glass.
• Descale steam system (monthly): Run a descaling program or flush with a commercial descaler following the manufacturer’s instructions. In hard-water areas such as Brisbane and Adelaide, this may need to be done more frequently.
• Inspect and replace door gaskets: A damaged seal reduces efficiency and cooking performance significantly.
• Final rinse: Always rinse the chamber with clean water after any chemical cleaning.

How to Clean Commercial Fridges and Freezers

Commercial fridges and commercial freezers run continuously. Neglected seals, mould, and dusty condenser coils cause food safety failures, higher energy bills and premature compressor failure.

Daily Cleaning Routine

• Record temperatures: Log fridge and freezer temperatures at the start of each shift — required for HACCP and Standard 3.2.2 compliance.
• Wipe surfaces: Clean handles, shelves and door gaskets with warm soapy water or food-safe sanitiser.
• Remove spills immediately: Liquid spills accelerate bacterial growth and odour if left.
• Inspect seals: Check gaskets for crumbs and mould and wipe clean with a damp cloth.

Weekly Deep Cleaning

• Empty safely: Transfer food into temporary cold storage during cleaning.
• Remove shelves and drawers: Wash in warm soapy water and allow to air dry before replacing.
• Clean interior walls and floor: Mild detergent or food-safe sanitiser; pay particular attention to corners and drainage holes.
• Disinfect gaskets: Scrub with a soft brush and sanitiser to prevent mould and maintain airtight closure.
• Vacuum condenser coils (monthly): Switch off the unit and vacuum or brush dust from condenser coils — dirty coils are the leading cause of preventable compressor failure.
• Check drain pans and tubes: Blocked drain lines cause pooling water and ice buildup.

How to Clean Commercial Deep Fryers

Old oil, grease buildup and food particles are the primary causes of fryer breakdowns, flavour deterioration and fire risk. Daily and weekly cleaning routines address each of these.

Daily Cleaning Routine

• Turn off and cool: Switch off and allow oil to reach a safe handling temperature before touching it.
• Filter or replace oil: Use a filtration system to extend oil life, or replace if quality has degraded.
• Remove debris: Skim food particles from the oil and baskets after every service.
• Wipe exterior: Damp cloth with mild detergent on all external surfaces.
• Top up oil: Refill to the manufacturer’s recommended level.

Weekly Deep Clean (Boil-Out)

• Drain oil: Carefully drain all oil. Follow your local council’s guidelines for commercial oil disposal.
• Scrub components: Remove and clean baskets, lids and detachable heating elements with warm water and degreaser.
• Prepare solution: Fill the tank with warm water and a commercial fryer cleaner.
• Boil out: Heat to a simmer for 15–20 minutes to loosen carbonised grease from the tank walls and heating elements.
• Rinse thoroughly: Drain, rinse with clean water at least twice and dry completely before refilling.

How to Clean Stainless Steel Benches

Stainless steel benches show smudges, streaks and water spots quickly if not maintained correctly. Always wipe in the direction of the grain — against it creates scratches that trap bacteria and are impossible to remove.

Daily Cleaning

• Wipe with a microfibre cloth and warm soapy water, following the grain of the steel
• Rinse with clean water to remove soap residue
• Dry immediately with a clean dry microfibre cloth to prevent water spots
• For fingerprints and light grease: equal parts white vinegar and water in a spray bottle, wipe with the grain, rinse and dry

How to Clean Commercial Dishwashers

Hard water, food debris and detergent residue are the main causes of poor dishwasher performance. Without consistent cleaning, the symptoms are cloudy glassware, streaked crockery and persistent odours.

Daily Cleaning Routine

• Empty and drain: Open the drain valve and empty the wash tank at the end of every service.
• Remove and rinse filters and strainers: Wash under warm running water to remove food scraps and grease.
• Clean spray arms: Remove, rinse and check every hole for blockages — a single blocked hole reduces washing pressure across the full load.
• Wipe interior: Soft brush and warm soapy water on chamber walls, door gasket and corners.
• Wipe exterior: Handles and controls with sanitiser.
• Leave door ajar overnight: Allows air circulation, prevents mould and ensures full drying of the chamber.

Weekly Deep Clean and Descaling

• Run descaling cycle: Commercial descaler or manufacturer-approved solution to dissolve mineral and limescale buildup — critical in hard water areas.
• Scrub hard-to-reach areas: Rinse arms, corners and filters where grease builds unnoticed.
• Check dosing systems: Confirm detergent and rinse-aid dosing is accurate — incorrect dosing is the most common cause of substandard washing results.
• Inspect seals and fittings: Replace cracked or mouldy door gaskets; check for leaks around hoses.

Commercial Kitchen Cleaning Schedule

Compliance and Safety

Standard 3.2.2 of the Australia New Zealand Food Standards Code requires food businesses to maintain food premises in a clean condition and to have documented cleaning procedures accessible to all staff. Local council inspectors will review your cleaning schedule, temperature logs and pest control records at inspection. A well-maintained cleaning logbook demonstrates that your standards are consistent — not just when the inspector calls.

Fines, forced closures and reputational damage are the practical consequences of failing to maintain cleaning standards. Document everything, train all staff on your procedures and review the schedule whenever you add new equipment or change your menu.

Practical Tips

• Clean as you go: Wipe spills immediately rather than leaving them for end-of-service — it reduces total cleaning time significantly
• Old toothbrush for tight spaces: Fryer corners, fridge gaskets and spray arm holes are all easier to clean with a stiff brush
• Colour-coded cloths: Assign specific colours for benches, fridges and sinks to prevent cross-contamination between areas
• Schedule deep cleans strategically: After lunch service or before a quiet service — not during peak hours
• Rotate cleaning responsibility: Rotating duties keeps standards consistent and ensures all staff are trained and accountable
• Invest in microfibre cloths: Less streaking, longer lifespan than disposable cloths, better result on stainless steel
