A kitchen deep clean goes beyond a daily wipe-down: it means stripping grease, limescale and bacteria from every surface, appliance and hidden gap, then disinfecting to a standard rather than just to appearance. Homeowners with built-up grease, renters approaching end of tenancy, and anyone after building work benefit most. Whether you do it yourself or hire a professional depends on time, the state of your oven and extractor, and how confident you are following BS EN disinfectant standards correctly.
TL;DR:
- Deep cleaning requires removing grease and residue from all zones, including inside cabinets, appliances, and hard-to-reach areas, with specific attention to contact times and disinfectant standards.
- The recommended cleaning order starts with decluttering, pre-cleaning greasy surfaces, cleaning appliances individually, disinfecting surfaces for the correct duration, and concluding with floors and ventilation.
- Using detergent first to lift grime before disinfectant ensures effective sanitation, and separate tools should be used for raw-food areas to prevent cross-contamination.
- Heavy appliances like ovens, extractors, and fridges often need a combination of soaking, scrubbing, or specialized professional attention due to built-up grease and carbon deposits.
- Costs vary based on kitchen size, appliances, and access, with professional services typically starting at around £119, and a detailed checklist helps prevent missed areas during DIY cleaning.

What a kitchen deep clean includes
A proper deep clean treats the kitchen as a series of zones, not a single job. Work surfaces and splashbacks need cleaning with detergent first to lift grease, then disinfecting once visibly clean, since a disinfectant applied over grime rarely works as intended. Sinks get the same two-stage treatment, with particular attention to the plughole and tap base where limescale and residue collect.
Cabinets rarely need daily attention, but the insides, handles and the gap above wall units gather dust and grease that a normal clean skips. Floors, skirting boards and any wall area near the hob catch splatter that hardens over weeks, so they need scrubbing rather than mopping alone.
- Work surfaces, splashbacks and sinks: detergent first, then a disinfectant left for its stated contact time.
- Cabinets and storage: exterior wipe-downs weekly, interior shelves and handles less often but not skipped.
- Floors, skirtings and walls: scrub grease-splatter zones near the hob, not just visible dirt.
- Bins, extraction and appliance interiors: empty and disinfect bins, clean the extractor canopy and filters, and clean inside the oven, fridge and dishwasher.
Anyone briefing a cleaner, whether a family member or a professional deep clean, can use this list as a checklist to confirm nothing gets missed.
An efficient order to work through the kitchen
Deep cleaning in the wrong order means redoing work. Cleaning the floor before the extractor, for example, means grease dust falls back onto a surface you have already finished.
- Declutter and empty bins first. Remove perishables, take rubbish out and clear surfaces so nothing is in the way.
- Pre-clean greasy areas with detergent. Loosen grease on the hob, splashback and extractor before any disinfectant goes on.
- Tackle appliances one at a time. Start soaking oven racks or trays while you work on other areas, so contact time is not wasted waiting.
- Disinfect surfaces and leave for the stated contact time. Rushing this step is the most common reason disinfecting fails, since manufacturer-stated contact times exist for a reason.
- Work top to bottom. Cabinets and walls before worktops, worktops before floors, so debris falls downward rather than back onto cleaned areas.
- Finish with floors, then ventilation. Mop last and open windows or run the extractor to clear fumes and let surfaces dry fully.
For a kitchen that has not had proper attention in a while, break the job into short sessions rather than one exhausting afternoon.
Pro Tip: Use the 20-minute rule: set a timer and commit to one zone (the oven, the extractor, or under the sink) for 20 minutes at a time, rather than trying to finish the whole kitchen in one sitting.
Chemicals, tools and safety for a proper deep clean
Detergent, disinfectant and sanitiser are not interchangeable. Detergent removes grease and food residue; disinfectant kills bacteria and viruses but only works once the surface is already clean; sanitiser typically combines both actions at a lower strength, suited to lighter jobs. The Food Standards Agency is clear that surfaces should be cleaned with detergent before any disinfectant is applied, since grease and grime can stop a disinfectant working.
Disinfectants must meet BS EN 1276 or BS EN 13697 and be left for the contact time stated on the label. Skipping the stated contact time, even by a minute or two, undermines the whole point of disinfecting.
- Check the label for BS EN 1276 or BS EN 13697 before buying a kitchen disinfectant.
- Use colour-coded cloths and separate buckets for raw-food areas, worktops and floors to avoid cross-contamination.
- Wear gloves and, for oven cleaners or strong degreasers, ventilate the room properly.
- Store chemicals away from food and out of reach of children, and never mix bleach-based and ammonia-based products.
Deep-cleaning the hardest appliances
Ovens, extractors, fridges and dishwashers cause most of the frustration in a kitchen deep clean, largely because grease and carbon build up gradually and go unnoticed.
- Oven: soak racks and trays in hot water and detergent while a suitable oven cleaner works on the interior; heavy carbon build-up on glass doors or heating elements is often better left to a specialist who can strip it safely.
- Extractor canopy and filters: filters can usually be soaked and scrubbed at home, but ducting that runs into walls or ceilings is a job for a professional, particularly if grease has hardened inside it.
- Fridge and freezer: defrost fully before cleaning, wipe shelves and door seals with detergent then a mild disinfectant to prevent odours, and clear dust from the coils at the back to keep the unit running efficiently.
- Dishwasher and microwave: run an empty hot cycle with a dishwasher cleaner to clear residue in the filter and seals, and use steam (a bowl of water and lemon, heated briefly) to loosen dried splashes in the microwave before wiping.
Dishwashers rated for disinfection or a boiling-water cycle can stand in for chemical disinfection on small items when needed.
When to call in a professional and what it costs
A DIY deep clean works well for most kitchens, but certain situations tip the balance towards hiring someone. End-of-tenancy cleaning is one, since landlords and agents often expect documented proof of a professional-standard clean before returning a deposit. Heavy carbon build-up in an oven, extractor ducting that needs dismantling, or simply not having the time are the other common triggers.
- Professionals typically inspect the kitchen first and can supply photographic evidence of the finished work.
- Add-ons such as inside-oven or inside-fridge cleaning are usually priced separately from a standard deep clean.
- Cost depends on kitchen size, the number of appliances included, access (ground floor versus a lift-only flat) and whether the booking is same-day.
- Ask for an itemised quote and check whether a re-clean guarantee is included before booking.
How Book My Cleaning delivers a kitchen deep clean
A kitchen deep clean can be offered as a fixed-price job rather than an hourly guess, with prices shown before booking and a written checklist that mirrors the room-by-room approach above. Inside-oven, inside-fridge and other add-ons can be listed separately so you only pay for what your kitchen needs. Cleaners may arrive in uniform, and some jobs carry a re-clean guarantee if anything falls short.
A cleaner's perspective: quick habits and common oversights
Most kitchens stay cleaner for longer through small daily habits: wiping the hob after cooking, swapping damp cloths before they start smelling, and giving door handles and taps a quick wipe. The oversights that catch people out are monthly ones: extractor filters, the dust on fridge coils, and the inside of the bin itself.

Book My Cleaning: fixed prices for a kitchen deep clean
If a DIY session feels like more than you want to take on this weekend, Book My Cleaning's deep cleaning service starts from £119, with prices for oven, fridge and other add-ons shown before you confirm anything.
Moving out of a rented kitchen calls for a different checklist, so the end-of-tenancy cleaning option is worth checking separately. Every booking carries the same 72-hour re-clean guarantee and vetted, DBS-checked cleaners, and you can check prices or book online in under a minute.

FAQ
How much would a kitchen deep clean cost?
Professional kitchen deep cleans are usually priced as part of a wider deep clean service rather than sold separately. Book My Cleaning's deep cleaning service runs from £119 to £329 depending on property size, with add-ons like an inside-oven clean priced separately.
What does a kitchen deep clean consist of?
It covers detergent-cleaning and disinfecting worktops, splashbacks and sinks, cleaning cabinet interiors and exteriors, scrubbing floors and grease-splatter zones near the hob, and cleaning inside major appliances such as the oven, fridge and extractor. Bins and the extraction canopy are also included, since they collect grease and bacteria that a daily wipe misses.
What is the best way to deep clean my kitchen?
Work through the kitchen in order: declutter and empty bins, pre-clean greasy areas with detergent, disinfect and leave surfaces for the stated contact time, then work top to bottom and finish with floors and ventilation. Tackling appliances individually, rather than all at once, avoids wasted disinfectant contact time and rework.
What is the 20-minute rule of cleaning?
It is a timeboxing method where you commit to cleaning one zone, such as the oven or the extractor, for 20 minutes rather than attempting the whole kitchen in one long session. It works well for tackling a kitchen deep clean gradually over several days without it feeling unmanageable.
