Kitchen Deep Clean, Step by Step

Most kitchen deep cleans go wrong on order and chemistry. Here is the sequence we work in, why grease and mineral build-up need opposite approaches, and an honest estimate of what the oven will cost you in time.

The short answer

  • Grease and mineral build-up need opposite chemistry. An alkaline degreaser lifts cooking fat, and a mild acid such as citric acid dissolves the scale on taps, glass and stainless. No single product does both well.
  • Order is half the job. Removable parts go into a hot soak first, high surfaces come before low, and all degreasing is finished before the floors are touched.
  • The tops of the kitchen cupboards hold a film of airborne grease with dust set into it. That needs dwell time and 2 or 3 passes.
  • A neglected oven is realistically 60 to 120 minutes of hands-on work, most of it on the racks and the inside of the door glass. Anyone promising 20 minutes is describing a light oven or leaving the racks out.
  • None of this needs bleach, fragrance or antibacterial agents. Hot water, the correct alkaline or acid choice, the right brush, the right tools for the surface, and time.

The kitchen is where we see the most effort produce the least result. Usually the order is wrong, the chemistry is wrong for the mess in front of it, and the product gets wiped away 5 seconds after it lands. This is the sequence we work in, and it slots into the wider house cleaning schedule and checklist as the longest single room in the house.

Grease and scale are opposite problems

Fat responds to alkalinity. An alkaline degreaser loosens cooking residue so it lifts onto a cloth, which is why it works on cupboard fronts, rangehood housings and the film above the stove. Acid does close to nothing on baked-on fat. Mineral build-up runs the other way: the white crust on a tap, the cloudy haze on a glass splashback, the ring in the kettle and the scale in a stainless sink are alkaline deposits, and a mild acid such as citric acid takes them off. Scrubbing a tap with a degreaser gets nowhere for that reason, and it is the same reason vinegar is oversold as a general cleaner despite being genuinely useful on scale.

2 products, 2 jobs. Alkaline for anything the cooking created, acid for anything the water left behind. Work out which one you are looking at before you spray, because using both on the same spot in the same minute neutralises them.

Never combine cleaning products. Bleach must never be mixed with ammonia, with vinegar or citric acid, or with any other cleaner, because those combinations can release toxic gas. Do not layer an acid over an alkaline product on the same surface either. Rinse fully between steps, and wipe the surface down with clean water before switching from one to the other. We do not use bleach at all, which removes that risk from the house entirely.

Soak first, so time works while you do

The first physical act in a kitchen deep clean is filling something hot. Rangehood filter, oven racks, drip trays, the removable knobs and burner caps, the sink strainer. They go into the hottest water the sink or a laundry tub will give you with an alkaline degreaser, and they stay there for 30 to 60 minutes while you clean everything else. Metal that has soaked for half an hour wipes clean under almost no pressure.

Dwell time on vertical surfaces works the same way, and it is the step people skip most. Spraying and immediately wiping just moves grease sideways. Give a degreaser 5 to 10 minutes on a cupboard front before you touch it, and re-wet it if it dries, because a dried product has stopped working.

The top of the cupboards

Airborne grease rises, drifts and lands, and the flat surfaces above eye level catch most of it. Over a year or 2 that becomes a tacky amber film with dust set into it, and because nobody sees it, nobody addresses it. It is a standing entry on the list of spots most cleans miss.

HEPA vacuum the loose dust off first so you are not turning it into paste. Apply degreaser and leave it. Come back, work it with a stiff brush or a plastic scraper held flat, and lift the residue onto a cloth. Then repeat: on a badly built-up surface the first pass only softens the top layer, and the second pass clears it. Finish with a clean water wipe so no residue remains to catch the next round of dust. The same treatment goes to the top of the fridge, the top of the rangehood and the top edge of the door frames.

Rangehood and filter

The soaked filter comes out, gets brushed along the direction of the mesh, gets rinsed hard with hot water and drains completely before it goes back. If the water runs out of it cloudy, soak it again. A saturated filter stops pulling air properly, so more grease stays airborne and lands on the cupboard tops you have just done. While the filter is out, degrease the cavity above it, the fan housing you can reach and the underside of the hood, then the outer surfaces. Wipe stainless along the grain.

Splashback, stovetop and where abrasives belong

Splashbacks take the same alkaline approach as the cupboards. Glass and stainless splashbacks carrying mineral marks need a mild acid once the grease is gone. Grease first, then mineral, because the acid cannot reach the deposit through the film.

Stovetops depend on the surface. Gas trivets and cast iron go into the soak and come out to an abrasive pad. Enamel and glass cooktops get degreaser, dwell time and a plastic scraper held at a low angle, which lifts burnt-on sugar far better than scrubbing. Abrasives are a main tool for us on the surfaces that can take them.

  • Fine for: oven racks, cast iron trivets, stainless sinks worked along the grain, oven door glass.
  • Not for: glass and ceramic cooktops, laminate and stone benchtops, painted or powder-coated surfaces, non-stick, anything anodised or coated, and any tap with a brushed or coloured finish.
  • If you are unsure, test in a hidden spot first and use the lightest grade that does the job.

The oven, honestly

An oven that has not been done in a year takes 60 to 120 minutes of hands-on work, and most of that goes on the racks and the inside of the door glass. If a quote implies 20 minutes, either the oven is already in good condition or the racks are being left out.

  1. 1Racks out and into the hot soak at the very start, along with any side rails and trays.
  2. 2Degreaser into the cavity, on the walls, roof and floor, and left to dwell. Re-apply anywhere it dries out.
  3. 3Scrape the floor and the corners with a plastic scraper before wiping, so you are removing carbon rather than spreading it.
  4. 4Door glass after the cavity work. Many oven doors come apart so you can get between the panes. If yours does not, clean what you can reach and say so.
  5. 5Racks out of the soak, steel wool along the bars, rinse, dry, back in.
  6. 6Wipe the cavity out with clean water twice, then leave the door open to dry.

We do this without caustic oven products and without fumes, which matters when someone is home, when there are pets in the house, or when the kitchen is open plan and the smell would carry through everything. It takes more time, and we have accepted that trade across the whole natural house cleaning standard: fragrance-free, no bleach, no antibacterial agents, no dyes, and none of the ingredients we exclude.

The fridge, including the parts behind it

Shelves and drawers come out and get washed in the sink, not wiped in place. Glass shelves need to come up to room temperature before hot water goes near them. Inside, plain warm water and a mild alkaline is enough, because a fridge interior is a food surface and does not want residue left on it.

Almost everyone misses 2 areas. The door seals, where the rubber concertinas and holds crumbs, spills and sometimes visible mould: run a soft brush into each fold, then dry the fold properly, because leaving it damp is how it returns. And the condenser coils at the back or underneath, which collect a dense felt of dust that makes the motor work harder. HEPA vacuum those gently with a brush attachment, with the fridge switched off at the wall.

Kickboards and the gap beside the fridge

The toe space under the cupboards and the narrow gap beside the fridge collect everything: crumbs, dried spills, hair, and in an older Brisbane home, a surprising volume of fine dust. Pull the fridge out if the floor allows it. Vacuum the gap with the crevice tool, then wash the sides of the cabinetry and the fridge itself, which carries its own grease film on the side facing the stove. Kickboards get vacuumed along their base, then washed, then the floor edge behind them. If a kickboard clips off, take it off.

Sink and drain, then the floors

The sink is the last wet fixture because it has been your soaking bath all day. A mild acid does the work here: in the bowl, around the tap base, and on the aerator, which can be unscrewed and dropped into a small cup of acid solution for 20 minutes while you finish elsewhere. Rinse everything thoroughly. For the drain, hot water and bicarb followed by more hot water shifts ordinary build-up. Bicarb and vinegar together mostly fizz and cancel each other out, so they do very little. None of these are disinfectants, which is worth knowing before you assume otherwise: see do natural cleaners disinfect. The goal is physical removal of soil.

Floors are always last, in every room, because everything you dislodge from above lands on them. Vacuum, then mop, then leave. Working this way is the whole point of the correct order to clean a room, and it is the difference between finishing once and finishing 3 times.

How long a real kitchen deep clean takes

A neglected kitchen on its own is commonly 4 to 6 hours of genuine work, and it is usually the reason a whole home reset for a 3 bedroom house runs 20 hours, normally 2 cleaners across more than 1 day. That might seem like a long time, but it is how long the job takes to do properly. A reset works through the same list as a regular clean, on a home that has not had it done yet, so every item takes longer. We charge $85 per hour and we price the time. A lower price usually means fewer hours in your home.

The tools and the time do the work. The chemistry is only there to make the tools effective, which is why fragrance, bleach and antibacterial agents can come out of the kit without the clean suffering.

A regular weekly or fortnightly clean keeps a kitchen properly clean on its own, and the higher detail work rotates across visits, so the rangehood filter, the cupboard tops and the oven each come around on a cycle. A reset is the easiest place to start from, and it makes every visit after it faster. If you would rather not give up a weekend to it, the deep clean reset is this method applied to the whole house, and you can tell us which areas matter most before we start so those get the priority.

Beyond Clean Living is a cleaning service, not a health service. Everything here is described in terms of the home and what is in it: grease, dust, mineral build-up, and the ingredients we choose to leave out, which are synthetic fragrance and parfum, hormone-disrupting chemicals, SLS, parabens, phthalates, antibacterial agents, bleach, dyes and essential oils. None of it is health advice, none of it treats or prevents any condition, and it is never a replacement for guidance from your doctor or specialist. Belinda's cleaning business is run separately from her clinical practice.

Common questions

How long does a kitchen deep clean take?

A kitchen that has not had a thorough clean in a year or more is commonly 4 to 6 hours of hands-on work, and the oven alone accounts for 60 to 120 minutes of that. A well maintained kitchen takes far less, because the amount of build-up drives the time more than the size of the room.

What is the correct order for a kitchen deep clean?

Put removable parts into a hot soak first, then work from high to low: cupboard tops, rangehood, cupboard fronts and doors, splashback and stovetop, oven, fridge, kickboards and the gap beside the fridge, sink and drain, and floors last. All degreasing is finished before the floors are touched, because everything you dislodge from above lands on them.

Why does grease need a different product to limescale?

They are chemically opposite. Cooking fat responds to an alkaline cleaner, which loosens it so it can be lifted away, while mineral deposits such as tap scale and the cloudy film on glass are alkaline themselves and dissolve with a mild acid. The wrong choice produces almost no result no matter how hard you scrub.

Can you clean an oven without caustic chemicals or bleach?

Yes. It takes an alkaline degreaser, real dwell time, a plastic scraper for the burnt-on carbon, an abrasive pad on the racks after a long hot soak, and physical effort. It takes longer than a caustic product would, which is the trade we accept in exchange for no fumes in a home where people and pets are present.

Is it safe to mix bicarb and vinegar to clear a drain?

It is not dangerous, but it is largely ineffective, because the acid and the alkali neutralise each other and produce fizz rather than cleaning power. Hot water with bicarb, followed by more hot water, does more. What is genuinely dangerous is mixing bleach with ammonia, with vinegar or any other acid, or with any other cleaning product, and that must never be done.

How often should the rangehood filter and cupboard tops be cleaned?

For most households the rangehood filter benefits from a hot soak every 1 to 3 months depending on how much frying happens, and the cupboard tops need attention a few times a year. In our maintenance cleans this higher detail work rotates across visits, so each item comes around on a cycle instead of being done every time or forgotten entirely.
