How to Deep Clean a Kitchen — The Professional Sequence

The kitchen is the most complex room in the home to deep clean. It has more surface types, more appliances, more hygiene-critical areas, and more cross-contamination risk than any other room. It also has the most tasks that are frequently skipped in regular cleaning — the inside of the oven, the rangehood filter, the inside of cupboards, behind the fridge.

A kitchen deep clean done properly takes 2–4 hours depending on the size and condition. What separates a professional approach from an amateur one isn't time or effort — it's sequence and chemistry.

Do it in the wrong order and you're cleaning surfaces twice, dripping product onto things you've already cleaned, or working against yourself. Get the sequence right and the clean proceeds efficiently with no double-handling.

The Core Principle: Spray and Dwell First

The most important professional technique in kitchen cleaning is applying products before you start cleaning anything — then doing other work while they dwell.

Oven cleaner, degreaser on the stovetop, product on the rangehood filter, descaler on the taps — all of these benefit from dwell time. The chemistry works while you're busy elsewhere. By the time you get back to them, much of the work is already done.

Apply products at the start of each section. Don't spray and immediately wipe. Dwell time is what separates effective cleaning from pushing product around.

Step 1: Clear and Assess (10 minutes)

Before you touch anything with a cloth:

Remove everything from benchtops and surfaces. Everything. Small appliances, knife blocks, dish drains, utensil jars, everything. Put them on the floor or another surface temporarily. You need to clean every centimetre of the benchtop and the wall behind it — you can't do that cleaning around objects.

Empty cupboards you're going to clean inside. If this is a full deep clean, you're cleaning the inside of every kitchen cupboard. Remove the contents of one cupboard at a time as you get to it. Check use-by dates on pantry items as you empty them — a kitchen deep clean is the natural time to cull expired products.

Apply oven cleaner to the oven interior. The oven needs the longest dwell time of anything in the kitchen — a minimum of 30 minutes, and several hours for a heavily soiled oven. Apply the product now, close the oven door, and let it work while you clean everything else. You'll come back to it last.

Assess: Look for anything that needs specific treatment — stubborn grease buildup on the stovetop, calcium deposits on the sink taps, mouldy sealant around the sink.

Step 2: High Surfaces First (15 minutes)

Top to bottom, always. Anything cleaned below will have debris fall on it from above. Do high surfaces before low ones.

Top of overhead cupboards: These accumulate a mix of grease from cooking steam and dust. Wipe with a damp microfibre cloth and a degreaser. This surface is often ignored for years — be prepared for significant buildup.

Top of the fridge: Same issue — grease and dust combination. Wipe thoroughly.

Rangehood exterior and underside: The bottom face of the rangehood, and the surfaces around it, accumulate the heaviest grease concentration in the kitchen. Apply degreaser, leave to dwell for 2–3 minutes, then wipe.

Rangehood grease filter: Remove the filter (usually clips or slides out). If it's metal mesh, place it in very hot soapy water to soak, or run it through the dishwasher on a hot cycle. If it's a charcoal filter (non-washable), replace it. Leave the filter soaking while you continue.

Overhead cupboard exteriors: Wipe the outside faces and handles of all overhead cupboards. Handles accumulate significant grease from cooking and handling.

Step 3: Inside of Cupboards (30–45 minutes)

Do these before the stovetop and benchtops — crumbs and debris from cupboards fall downward and will land on surfaces below.

Method: Empty one cupboard at a time. Wipe the interior walls, shelves and the base of each cupboard with a damp cloth and a mild cleaning solution. A few drops of dish soap in water works well on most cupboard interiors. For shelves with greasy buildup (particularly near the stove), use a degreaser.

Drawer interiors: Remove drawers fully or pull them out as far as possible. Wipe the drawer base and walls. Remove and clean drawer organisers. Shake crumbs out of utensil drawers.

Hinge and handle areas: The inside faces of cupboard doors accumulate grime around hinges and handles. Wipe these specifically.

Replace shelf liner if it's worn or stained — this is the right time to do it while everything is out.

Step 4: Appliance Exteriors (20 minutes)

With high surfaces done, move to appliance exteriors. These go before the stovetop and benchtops because product drips and wipes from appliances may land on surfaces below.

Microwave exterior: Wipe the top, sides and front. Pay attention to the door handle and the control panel — these are high-touch surfaces.

Microwave interior: If not recently cleaned, now is the time. Place a bowl of water with vinegar inside, microwave for 3 minutes, leave for 2 minutes, then wipe. The steam loosens any splatter.

Fridge exterior: Wipe the door faces, handles, and the sides if accessible. Wipe the top of the fridge (already done in step 2 if it was greasy).

Fridge door seals: Wipe the rubber gaskets around the fridge and freezer doors. These collect food debris and can develop mould. Use an old toothbrush for the crevices.

Dishwasher exterior: Wipe the door face and handle.

Oven exterior: Wipe the outside face of the oven door, the control panel, and the sides. The area around the oven door crevice accumulates significant grime.

Step 5: Stovetop (20 minutes)

Apply degreaser at the beginning of this step and let it dwell for 5 minutes before wiping.

Gas stovetop:

1. Remove grates and burner caps. Place grates in the sink with hot soapy water to soak.
2. Spray the stovetop surface with degreaser and leave to dwell.
3. Wipe the stovetop surface with a damp cloth. Use a toothbrush or skewer to clear any blocked burner holes.
4. Scrub grates in the sink — a stiff brush with dish soap on soaked grates removes baked-on residue much more easily than scrubbing dry.
5. Dry grates before replacing — wet grates can cause burner issues.

Glass/ceramic stovetop:

1. Apply a ceramic stovetop cleaner (or baking soda paste for light residue) to the surface.
2. Use a dedicated glass stovetop scraper at a low angle for baked-on residue — never use abrasive pads or steel wool on ceramic glass.
3. Wipe clean with a damp cloth. Polish with a dry microfibre cloth.

Step 6: Splashback (10 minutes)

Tile splashback: Spray with a tile cleaner or diluted degreaser. Leave to dwell, then wipe. Use a grout brush on grout lines — kitchen splashback grout accumulates significant grease.

Glass splashback: Spray with glass cleaner or diluted vinegar. Wipe with a dry microfibre cloth.

Stone splashback: Use only pH-neutral cleaner — no acid, no bleach.

---

Step 7: Benchtops (15 minutes)

With everything above cleaned, the benchtops can now be done without anything falling onto them.

Wipe all benchtop surfaces from back to front — starting at the wall edge (which accumulates the most residue, particularly around the stove) and working toward you. Sanitise after wiping. Pay attention to the area around the sink and the area immediately beside the stove.

Return the items from benchtops and wipe the base of each item before replacing.

---

Step 8: Sink (10 minutes)

Basin: Scrub with a non-scratch pad and dish soap or a dedicated sink cleaner. Pay attention to the drain area and the overflow hole.

Taps: Descale with a cloth soaked in white vinegar held against the base of the taps and the tap body for 5 minutes. Wipe and polish. The area where the tap meets the sink base needs a toothbrush.

Under-sink cabinet: Open the under-sink cabinet and check for leaks, moisture, mould or pest evidence. Wipe the interior.

---

Step 9: Oven Interior (20 minutes)

By now the oven cleaner has had its full dwell time (at least 30 minutes, ideally longer for heavy ovens).

Remove racks (the soaked and scrubbed racks from earlier can now be dried and set aside).

Wipe the interior with damp cloths, rinsing frequently. Work from the oven ceiling (most splatter), then sides, then floor. Multiple rounds of wiping are usually needed to remove all chemical residue. Don't leave oven cleaner residue — it will smoke and smell on next use.

Oven door glass: Wipe the interior glass with the same product used in the cavity.

---

Step 10: Floor (15 minutes)

Always last. Sweep or vacuum first to collect all the debris that has fallen during the clean. Then mop with a food-safe floor cleaner, starting at the far wall and working toward the door. Get into the corners with a cloth or mop edge.

Behind and under the fridge: Pull the fridge out from the wall. Vacuum the condenser coils at the back with a brush attachment. Mop the floor underneath. Push the fridge back.

The Complete Sequence Summary

Order	Task
1	Apply oven cleaner (long dwell)
2	High surfaces — cupboard tops, fridge top, rangehood
3	Inside of cupboards and drawers
4	Appliance exteriors and microwave interior
5	Stovetop
6	Splashback
7	Benchtops
8	Sink and taps
9	Oven interior
10	Floor (always last)

This sequence ensures you never clean a surface and then drop debris onto it from above. Every step builds on the previous one without creating double-handling.
