After the last cover ends and the kitchen clears, daily cleaning handles the visible mess: wiped surfaces, swept floors, sanitised prep areas. It’s necessary work. But it doesn’t address the grease that has migrated up into canopy baffles, the carbon deposits baked onto oven cavities, or the residue that has built up beneath deep fryers over weeks of service.
That’s what a commercial kitchen deep clean is for.
A deep clean is a systematic, top-to-bottom process targeting the grease, scale, and bacteria that accumulate in areas daily cleaning doesn’t reach. In a commercial kitchen environment — where the Food Safety Act 1990 and HACCP requirements apply — it’s a compliance requirement, not just a hygiene preference.
Key Takeaways – A commercial kitchen deep clean covers canopies (external surfaces, baffles, and grease filters), deep fryers, cooking ranges, floors, surfaces, and backsplash — areas not addressed by daily cleaning – TR19 internal ductwork and fan unit cleaning is a separate specialist service; Atlon’s kitchen deep clean covers canopy surfaces, baffles, and grease filters, not internal extraction systems – Deep cleans form part of a HACCP cleaning schedule, which is a legal requirement under the Food Safety Act 1990 – Cooking equipment and extraction are the two highest-risk areas for grease accumulation — and the two areas EHO inspectors focus on most closely – Commercial kitchen deep clean pricing in Manchester starts from £600; accurate quotes require photos or an on-site assessment
What Daily Cleaning Misses
Daily and weekly cleaning routines are designed for speed and consistency. They keep surfaces hygienic and kitchens presentable, and they’re essential. What they’re not built for is the slower accumulation of grease, carbon, and limescale that builds up in less accessible areas.
The areas a daily clean typically doesn’t reach:
- Behind and beneath cooking equipment: Heavy ranges, fryers, and griddles rarely move. Grease from splatter and overflow accumulates on surfaces behind and beneath them over time.
- Canopy baffles and grease filters: Baffles trap aerosolised grease before it reaches the extraction ducting. They saturate over weeks of cooking and need removing, degreasing, and reinstalling — a process daily cleaning doesn’t allow for.
- Inside oven cavities and under hob grates: Baked-on carbon requires specific degreasers and dwell time to break down properly.
- Floor edges and drain channels: Grease and food debris accumulate along floor edges and in drainage channels, where they become a food source for pests if left unaddressed.
- Backs of door handles, hinges, and gaskets: EHO inspectors specifically check these areas. They’re contact points that carry bacteria and are almost never addressed in a daily clean.
A commercial kitchen deep clean addresses all of these systematically.
What’s Included in a Commercial Kitchen Deep Clean
Extraction Canopies, Baffles, and Grease Filters
Canopy surfaces, internal baffle chambers, and removable grease filters are degreased, removed where applicable, cleaned with appropriate degreasers, and reinstalled. This removes the accumulated grease load that reduces extraction efficiency and creates a fire hazard.
Important scope note on ductwork: Internal ductwork cleaning — the extraction ducting and fan units running from the canopy through the building — requires a specialist duct hygiene service under TR19 guidelines. This is separate from a kitchen deep clean. Atlon’s commercial kitchen cleaning covers canopy surfaces, baffles, and grease filter cleaning; if you need internal ductwork assessed or cleaned, a TR19-certified contractor should be engaged separately.
Deep Fryers
Deep fryers carry among the heaviest grease loads in any kitchen. The deep clean process covers:
- Draining and disposing of used oil
- Degreasing the fryer tank, exterior, and heating elements
- Cleaning the drain valve and surrounding area
- Cleaning beneath and behind the fryer unit
Cooking Ranges, Ovens, and Griddles
- Grate and burner removal and soaking
- Degreasing of oven interiors, including walls, racks, and door seals
- Griddle plate cleaning to remove carbon deposits
- External surface cleaning on all cooking equipment
Floor Scrubbing
Commercial kitchen floors accumulate grease that daily mopping doesn’t fully address. The deep clean process includes:
- Dry removal of loose debris
- Degreasing floor surfaces with industrial-grade products
- Mechanical scrubbing where equipment permits
- Edge and corner scrubbing
- Floor drain cleaning and degreasing
Walls, Backsplash, and Splashback Panels
Tiled or stainless steel splashback panels receive grease splatter from daily cooking. These are degreased and wiped down, and tile grout lines are addressed where grease has penetrated.
Work Surfaces and Prep Areas
All stainless steel preparation surfaces, shelving, and work benches are degreased and sanitised — including the surfaces themselves, the legs and frames, and the undersides where grease and debris collect.
Sinks and Drainage
Sink bowls, tap fittings, and waste trap areas are cleaned and descaled. Drainage outlets are inspected and cleared.
Cold Store Exteriors
The external surfaces of refrigeration units — doors, handles, seals, and tops — are cleaned as standard. Internal refrigeration cleaning can be scoped as an add-on.

Why Deep Cleans Are a Compliance Requirement
A commercial kitchen deep clean isn’t simply a preference — it’s embedded in the legal obligations applying to all UK food businesses.
HACCP (Hazard Analysis and Critical Control Points) is the food safety management system required by the Food Safety Act 1990. Under HACCP principles, cleaning schedules are documented control measures. The HACCP plan must specify what areas are cleaned, how often, by whom, and with what products — and deep cleans form part of that documented schedule.
EHO inspections under the Food Hygiene Rating Scheme assess three areas: hygienic food handling, the condition of premises, and food safety management (which includes documentation). A kitchen showing accumulated grease in baffles, carbonised oven cavities, or dirty floor drains will score poorly on premises condition. Absent or outdated cleaning schedule records will affect the food safety management score.
Cooking equipment is responsible for 25% of all restaurant fires according to UK fire service statistics, with grease accumulation in extraction systems identified as a primary cause. A regular deep clean reduces the fire risk that uncleared grease creates in operational kitchens.
The Food Standards Agency’s 2026 data shows that across 485,459 rated food businesses, 78.2% hold a 5-star hygiene rating. Manchester’s average is 4.5 out of 5, with 338 food businesses in the city holding a 0–2 star rating — a level at which the FSA considers improvement necessary. In almost all low-scoring premises, cleaning condition is a contributing factor (Food Standards Agency, FHRS data, April 2026).
How Often Should a Commercial Kitchen Be Deep Cleaned?
Frequency depends on how intensively the kitchen is used:
- High-use kitchens (daily service, 12 or more hours of cooking): every 3 months
- Moderate-use kitchens (daily service, under 12 hours): every 6 months
- Light-use kitchens (fewer than 5 days per week): every 12 months
EHO inspectors may ask to see your cleaning schedule and records. If the last deep clean was more than six months ago and you have no documentation, that’s a gap in your food safety management evidence.

How Much Does a Commercial Kitchen Deep Clean Cost in Manchester?
Across the UK market, professional commercial kitchen deep cleans typically range from £450 to £2,800 depending on kitchen size, equipment volume, and current condition.
Atlon Cleaning Services’ commercial kitchen deep clean starts from £600. Because pricing depends directly on the size of the kitchen and the amount of equipment, accurate quotes require photos or an on-site assessment rather than an estimate from floor area alone.
To get a quote: send photos of your kitchen (equipment, canopy, floor, and general overview) using the contact form at /commercial-cleaning-services/commercial-kitchen-cleaning/, or call 0161 524 9966 to arrange an assessment visit.

What to Expect on the Day
A professional commercial kitchen deep clean typically takes:
- Small kitchens (café, fast food outlet, single-chef setup): 4–6 hours
- Medium kitchens (full restaurant, 2–4 cooking stations): 6–10 hours
- Large kitchens (hotel kitchen, multi-outlet, high-volume): 10–16 hours or overnight
The kitchen needs to be unoccupied, with gas and electrical equipment isolated where safety requires it. If you’re booking a post-service clean, confirm cool-down time for equipment before the cleaning team arrives. The team works top-to-bottom — canopies and wall surfaces first, then cooking equipment, then floors — to avoid re-contaminating cleaned areas.
Frequently Asked Questions
Is a commercial kitchen deep clean the same as a daily clean?
No. Daily cleaning maintains hygiene on accessible surfaces. A deep clean addresses accumulated grease and bacteria in areas daily cleaning doesn’t reach — canopy baffles, behind equipment, underneath fryers, inside oven cavities, and along floor edges. Both are necessary; they serve different purposes.
Do you clean inside the extraction ducting?
No. Internal ductwork and fan unit cleaning falls under TR19 duct hygiene guidelines and requires a specialist contractor with different equipment and certification. Atlon’s commercial kitchen cleaning covers canopy surfaces, baffles, and grease filters — not internal extraction systems.
Do I need to supply cleaning products?
No. Professional commercial kitchen cleaning teams bring their own industrial-grade degreasers, sanitisers, and equipment. These are different from domestic or standard commercial products and are suited to the grease loads found in working kitchens.
How do I book a commercial kitchen deep clean in Manchester?
Send photos of your kitchen showing the equipment, canopy, floor, and general layout for an accurate quote, or call 0161 524 9966 to arrange an assessment. We cover Manchester and the wider North West.
Does the clean need to happen out of hours?
For most kitchens, yes. The clean is most effective when the kitchen is not in service, and some processes require the kitchen to be clear. Most operators schedule deep cleans to run overnight between service days or on a closed day.
