Commercial kitchens on the Sunshine Coast work harder than most people realise. Between breakfast service and closing, a busy cafe in Mooloolaba or a restaurant in Hastings Street processes hundreds of meals through a space designed for efficiency, not ease of cleaning.

Daily cleaning keeps things operational. But deep cleaning — the kind that gets into extraction hoods, behind equipment, and into floor drains — is what keeps kitchens compliant with Queensland food safety regulations and extends the life of expensive equipment.

We’ve cleaned commercial kitchens across the Sunshine Coast for years, from small Caloundra cafes to large Noosa restaurant kitchens. This checklist covers what a thorough deep clean should include and what gets missed most often.

Frequency: How Often Is “Deep” Enough?

Queensland’s Food Safety Standards require kitchens be maintained in a clean and sanitary condition. Local council health inspectors expect evidence of regular deep cleaning beyond daily maintenance.

For most Sunshine Coast hospitality businesses:

• High-volume kitchens (restaurants doing 200+ covers daily): Monthly deep clean
• Standard cafes and restaurants: Every 6-8 weeks
• Lower-volume or seasonal operations: Quarterly, with additional cleans before and after peak tourist season

The Sunshine Coast’s humid climate means grease, mould, and bacteria accumulate faster than in drier regions. What passes for acceptable in Melbourne might not fly here.

The Full Deep Clean Checklist

Extraction and Ventilation Systems

This is the area that fails health inspections most frequently. It’s also a fire risk when grease accumulates in extraction hoods and ductwork.

• Remove and degrease all hood filters. Soak in a commercial degreaser solution, scrub, rinse, and dry completely before reinstalling.
• Wipe down the interior of the extraction canopy, including the plenum chamber behind the filters.
• Check and clean the exhaust fan. Grease buildup on fan blades reduces airflow efficiency and creates fire risk.
• Inspect ductwork access panels. Full duct cleaning requires a specialist, but you can assess visible buildup through access points.

Cooking Equipment

Every piece of cooking equipment needs individual attention during a deep clean.

• Grills and flat tops: Cool completely, scrape, degrease, scrub with a grill stone or heavy-duty pad, rinse, and re-season if required.
• Ovens and combi ovens: Run the self-clean cycle if available, then manually clean door seals, glass, and racks. Combi ovens need descaling — Sunshine Coast water minerals cause buildup faster than in drier regions.
• Fryers: Drain oil, fill with water and fryer-specific cleaner, boil for 20 minutes, drain, scrub interior walls and heating elements, rinse thoroughly.
• Salamanders and char grills: Remove grates, soak and scrub. Check gas burner ports for blockages.

Refrigeration

Cold storage is where deep cleans often get cut short because pulling everything out takes time.

• Remove all stock from each unit. Check expiry dates as you go — deep clean day is also stock audit day.
• Remove shelves and drawers. Wash in warm soapy water, sanitise, and dry.
• Clean interior walls, ceiling, and floor of each unit with a food-safe sanitiser.
• Vacuum or brush condenser coils on the back or underside of each unit. Dust-clogged coils make refrigeration work harder, increasing energy costs and shortening equipment life.
• Check door seals for damage or mould. Replace any seals that don’t close firmly.

Floors, Walls, and Drains

The less glamorous but equally important part of a commercial kitchen deep clean.

• Floor drains: Remove grates, clear debris, scrub drain channels with a stiff brush and degreaser, flush with hot water. In Sunshine Coast humidity, neglected floor drains become breeding grounds for drain flies and bacteria.
• Floor surfaces: Sweep thoroughly, then scrub with a commercial floor degreaser. Focus on areas under and behind equipment where grease accumulates.
• Walls and splashbacks: Degrease all wall surfaces behind cooking equipment. Tiled walls need grout inspection — damaged grout harbours bacteria.
• Ceiling tiles and light fittings: Remove and clean light diffusers. Check ceiling tiles for grease staining or water damage.

Storage, Handwash Stations, and Staff Areas

These areas are overlooked in many deep cleans but are regularly inspected by health officers.

• Pull all stock from shelving. Wipe down shelves with a food-safe sanitiser.
• Check for pest evidence — droppings, gnaw marks, or webbing. Report any findings to your pest control provider.
• Clean and sanitise all handwash basins. Ensure soap dispensers and paper towel holders are functional.

Documentation Matters

Keep a dated log of every deep clean. Queensland health inspectors look for this documentation. Record the date, areas covered, who performed the clean, and any maintenance issues identified.

The Sunshine Coast Factor

Our coastal climate adds specific challenges. Salt air accelerates corrosion on stainless steel, humidity promotes mould in poorly ventilated areas, and the seasonal population swing means kitchens need to be in peak condition right when they’re working hardest.

Scheduling your deep cleans for early November (before peak season) and late April (after it winds down) gives you the best protection during the periods that matter most.

A clean kitchen isn’t just about passing inspections. It’s about equipment lasting longer, staff working in better conditions, and food coming out consistently. On the Sunshine Coast, where word of mouth and online reviews can make or break a hospitality business, it’s worth doing properly.
