How Often Should a Restaurant Be Deep Cleaned? A Melbourne Guide

If you run a restaurant, café, or commercial kitchen in Melbourne, you already know daily cleaning isn't the same as a deep clean. Wiping down benches and mopping floors keeps things presentable — but grease builds up inside exhaust canopies, drains trap food waste, and coolroom coils collect dust whether or not the kitchen looks clean on the surface. Knowing exactly how often to schedule a full restaurant deep cleaning in Melbourne, and what it needs to cover, is what actually keeps a kitchen compliant, safe, and free of pest and fire risks.

Deep Cleaning vs. Daily Cleaning — What's the Difference?

Daily cleaning covers what staff can reasonably do between services: wiping surfaces, sweeping and mopping floors, washing dishes, and taking out rubbish. A deep clean goes into the areas that daily routines never reach — behind and underneath equipment, inside exhaust hoods and ductwork, grease traps, floor drains, and refrigeration coils. These are exactly the areas Victorian food safety inspectors check first, because they're where grease fires start and pests take hold.

What Australian Food Safety Law Requires

Under Food Safety Standard 3.2.2 (part of the Australia New Zealand Food Standards Code), all food businesses are legally required to keep food premises, fixtures, and equipment clean to a standard that prevents contamination. Local Melbourne councils — including the City of Melbourne, Stonnington, Port Phillip, and Yarra — carry out regular inspections and can issue improvement notices, on-the-spot fines, or closure orders for hygiene failures. A documented deep cleaning schedule is one of the simplest ways to demonstrate compliance if an inspector asks.

How Often Should a Restaurant Be Deep Cleaned?

The right frequency depends on how much your kitchen actually cooks, not just how busy the dining room looks:

• High-volume kitchens (open 7 days, full-service or high-turnover QSR): deep clean monthly. Grease accumulates fast enough in these kitchens that quarterly cleaning leaves a real fire and pest risk.
• Standard full-service restaurants (5–6 services a week): deep clean every 3 months, which aligns with what most Melbourne health inspectors expect as a baseline.
• Cafés and lower-volume kitchens: every 3–4 months is usually sufficient, provided exhaust systems and grease traps are checked more frequently in between.
• Exhaust hoods and ductwork specifically: Australian Standard AS 1851 recommends more frequent servicing than the general kitchen deep clean — every 1–3 months for heavy-use kitchens — since grease buildup inside ductwork is a leading cause of commercial kitchen fires.

What a Professional Restaurant Deep Clean Actually Covers

A proper deep clean is far more than a heavier version of daily cleaning. At minimum, it should include:

• Exhaust hood and canopy degreasing — the single biggest fire risk in most commercial kitchens if left too long
• Grease trap cleaning — prevents blockages, odours, and council non-compliance notices
• Floor drain scrubbing — a major pest attractant when neglected
• Refrigeration and coolroom coil cleaning — dirty coils reduce cooling efficiency and increase energy costs
• Behind and underneath fixed equipment — ovens, fryers, and cooklines that rarely get moved
• Wall and ceiling degreasing around cooking areas
• Sanitising all food-contact surfaces to HACCP-aware standards

Signs Your Kitchen Is Overdue for a Deep Clean

Between scheduled cleans, a few warning signs mean it's time to bring a deep clean forward rather than waiting for the calendar: a persistent greasy smell that daily cleaning doesn't shift, visible grease sheen on walls or the exhaust canopy, slow-draining floor drains, an increase in fruit flies or pests near bins and drains, or feedback from staff that certain areas "never feel properly clean."

What Happens If You Skip It

Beyond the food safety risk, neglected deep cleaning has real financial consequences: council fines and improvement notices, closure orders that shut down trading during peak periods, higher pest control costs, increased fire risk from grease buildup in exhaust systems, and in some cases, invalidated insurance if a fire investigation finds inadequate kitchen maintenance. A fixed deep cleaning schedule is significantly cheaper than dealing with any of these after the fact.
