A residential kitchen takes more abuse than any other room in the house. Daily cooking, daily spills, food residue working into corners, grease building on cupboard doors, food smells embedding in soft surfaces. A weekly wipe-down doesn't fix any of it. The deep clean is what resets the kitchen, and most homeowners do it wrong in ways that damage their finishes.
We do residential deep cleaning across Sydney and the kitchen is usually the room with the most accumulated problem. Here's the method that actually works, plus what to avoid so you don't strip the finish off your bench or your floor.
Before You Start
Deep cleaning a kitchen properly takes around three hours for an average residential space, longer for big or heavily used kitchens. Set aside the time. Half-doing it is worse than not doing it because you end up with grease and dust redistributed rather than removed.
Pull everything off the bench. The toaster, kettle, knife block, fruit bowl, whatever else lives there. The bench has to be clear to clean properly.
Empty the sink and run hot water through the drain. Throw out the dishcloth and the sponge if they're more than a couple of weeks old. You're not cleaning anything with a dishcloth that's already harbouring bacteria. The NSW Food Authority has a detailed page on cleaning and hygiene at home, and the key point is that the cleaning tools themselves have to be clean, or you're spreading contamination rather than removing it.
Top to Bottom Order
Always work top to bottom so debris falls onto surfaces you haven't done yet, then gets cleaned off in the lower passes. Skip this order and you'll re-soil clean surfaces.
Start with the top of the cupboards and the rangehood. Dust and grease combine into a sticky film that builds up there. A microfibre cloth with warm water and a little dish soap handles most of it. Heavy build-up needs a degreaser. Avoid anything aggressive (Easy-Off Bam, oven cleaner) on cabinet wood or veneer because it'll damage the finish.
The rangehood filter goes in the dishwasher on its own cycle. Most domestic filters survive a dishwasher cycle fine. Heavily greased filters might need a soak in hot water with washing soda first.
Inside the Oven
The oven is the single most common spot people use the wrong product on. If you have a self-cleaning oven, use the self-clean cycle. If not, the safest approach is bicarb soda paste left overnight, then scrubbed and wiped off in the morning. It's slow but it won't damage anything.
Heavy build-up sometimes needs commercial oven cleaner. If you use one, follow the label exactly. Use gloves. Ventilate the kitchen. Never use oven cleaner on the racks if you're going to put them straight back in. Wash the residue off completely.
The oven door glass usually has baked-on splatter that needs paste plus scrubbing with a non-scratch scourer. Wipe out completely.
The Stovetop
Different stovetops, different methods. Gas stoves get the burner caps and trivets soaked in hot soapy water while you clean the cooking surface with a degreaser. Induction and ceramic glass cooktops need a specific glass cooktop cleaner (Cif or Bar Keepers Friend Cooktop Cleaner) and a microfibre. Never use abrasive pads on glass cooktops. They scratch, and the scratches catch grease forever after.
The Microwave Interior
Microwave a bowl of water with lemon juice for three minutes. The steam loosens everything stuck inside. Then wipe out with a microfibre. No chemicals needed.
The Fridge
This is where most people give up. Pull everything out. Throw away anything past its date, then wash the shelves and drawers in the sink with warm soapy water. Wipe the interior cabinet with warm water and a tiny amount of bicarb dissolved in. Avoid anything fragranced because the fridge picks up odours.
Pay attention to the seal. Wipe along the rubber gasket because mould and crumbs hide there. Replace the inside.
Don't forget the back of the fridge if you can reach it. Vacuum the coils if accessible. Dust on the coils makes the fridge work harder and burn more power.
Splashbacks, Tiles, and Grout
The splashback gets grease daily and rarely a full clean. Hot water with dish soap for the first pass, then a degreaser if there's visible build-up. Stone splashbacks need pH-neutral cleaner only. Glass splashbacks tolerate vinegar, but check the manufacturer if it's pricey custom glass.
Grout between kitchen tiles holds grease and food spatter. Apply bicarb paste and leave 15 minutes. Scrub with a stiff brush after. Hydrogen peroxide for heavy staining. Avoid bleach on coloured grout.
Cabinets and Drawers
Pull each drawer fully out and shake out the crumbs that collect at the back. Wipe the inside with a damp microfibre and mild detergent. Same for cupboards. The undersides of shelves usually have splatter that gets missed in a weekly clean.
Cabinet doors get a separate pass with a degreaser. Wood doors need a final dry wipe with a microfibre to remove any moisture left on the finish.
The Sink and Tap
Stainless steel sinks get cleaned with Bar Keepers Friend or a baking soda paste, scrubbed with a non-abrasive pad. Rinse fully because Bar Keepers Friend residue leaves a film. Granite or composite sinks need their specific cleaner.
The tap base and the area around the levers collect limescale fast. White vinegar on a paper towel wrapped around the base. Leave 30 minutes. Wipe off. The chrome should be back to its original finish.
Don't forget the underside of the tap spout. Limescale builds there and nobody looks.
The Floor (Last)
Sweep or vacuum first. Then mop with the right product for the floor type. Hard-finish timber takes Bona or equivalent. Vinyl and tile take a neutral or mild detergent in warm water. Stone tile needs pH-neutral. Never put a soaking-wet mop on timber.
The Bin
Pull out the liner. Wash the bin with hot soapy water inside and out. Let it dry fully before putting a fresh liner in.
What to Avoid
Spraying air freshener at the end. The smell hides the fact you missed something. If the kitchen smells fresh because you cleaned properly, you don't need air freshener.
Mixing chemicals. Bleach and ammonia produce toxic chlorine gas. Vinegar and bleach do too. Never combine them. Water only if in doubt.
Using one cloth for everything. The cloth that wiped the bin should not touch the bench. Colour-code or use disposable wipes.
Forgetting the kettle and toaster. Both have crumbs and limescale build-up. Descale the kettle every few months with white vinegar and water.
When Professional Cleaning Helps
A regular maintenance clean handles bench, sink, stovetop, and floor weekly or fortnightly. A proper kitchen deep clean covering everything above is usually a quarterly or twice-yearly job. Most regular cleaning packages don't include deep oven or fridge work. They're extras.
If you're booking a residential clean, ask specifically what the kitchen scope includes. A cleaner who says "we clean the kitchen" without naming the oven and fridge detail is doing surface-level kitchen cleaning. Rangehood work is usually missing too.
If you'd rather have someone else do the deep work, our deep cleaning service covers the full kitchen scope as part of every deep clean.
