How to Clean Kitchen Appliances: Fridges, Microwaves and More

To clean kitchen appliances, wipe any surface that touches food with a gentle plant based cleaner and a damp microfibre cloth, then wipe again with plain water so nothing is left behind. Clean exteriors and stainless fronts separately, always working with the grain. Steam loosens microwave grime, and a diluted enzyme cleaner lifts grease without harsh fumes.

Why appliances need their own cleaning approach

Your benchtops and splashback get a wipe most days. Your appliances, on the other hand, tend to get cleaned only when something goes visibly wrong: a spill bakes onto the oven floor, the fridge starts to smell, or the microwave roof is speckled with last week's pasta sauce. That gap is exactly why appliances deserve their own method rather than being lumped in with a general kitchen wipe down.

Three things make appliances different. First, many of their surfaces touch food directly, so what you clean with and how well you rinse actually matters. Second, they mix materials in close quarters: glass doors, painted steel, plastic seals, rubber gaskets and electrical controls all sit within a hand span of each other, and each wants a slightly different touch. Third, they trap heat, moisture and grease, which means grime sets harder and lingers longer than it does on an open bench.

Get the approach right and you save real time. A fridge that gets a proper wipe every few weeks never reaches the crusted, smelly stage that swallows an hour. The trick is matching the cleaner and the cloth to the surface, and knowing when a gentle method beats reaching for something aggressive. Across this guide you will see the same idea repeated: clean little and often, finish food contact surfaces with a plain water wipe, and let a versatile concentrate do the work of several bottles. For the wider picture, our full kitchen cleaning guide ties appliances together with benches, sinks and floors.

A quick word on safety before you start

Two rules keep appliance cleaning safe. First, never mix vinegar, lemon juice or any acid with other cleaning products, especially anything containing bleach or chlorine, because the combination can release harmful fumes. Stick to one cleaner at a time, and if you want to use vinegar for descaling, rinse the surface clear of other products first. Second, keep liquids away from electrical contacts, vents, control panels and the slots on a toaster. Spray your cloth, not the appliance, and wring the cloth so it is damp rather than dripping. Unplug small appliances before you wipe them, and let anything warm cool to the touch first.

Food contact versus everything else: the rule that guides it all

Before you spray anything, sort the surface into one of two camps. Food contact surfaces are any spot where food, ice or a clean plate might touch: fridge shelves, crisper drawers, the inside of a microwave, the interior walls of a fridge, the cavity of a toaster oven. Non food contact surfaces are everything else: the stainless front, the door handle, the control panel, the top of the range hood, the back and sides.

The distinction changes how you finish, not necessarily what you start with. On food contact surfaces, the golden rule is to leave nothing behind. Even a plant based cleaner should be wiped off with a clean damp cloth so the surface is residue free before food returns. On non food contact surfaces you have more latitude, and you can prioritise a streak free shine over residue removal.

This is one reason a single, genuinely versatile cleaner earns its place under the sink. Switching between a harsh degreaser for the oven, a separate glass spray for the door and a third product for the stainless front means more bottles, more residue risk and more guessing about what is safe near food. A plant based, enzyme activated concentrate diluted to the right strength handles interiors gently and exteriors cleanly, which keeps the whole job simpler. As a rough guide, a light everyday dilution sits around 5 to 10ml of concentrate per litre of water, while greasier jobs step up to 10 to 20ml per litre.

How to clean a fridge interior

The fridge is the appliance where hygiene matters most, because it stores food for days at a time at temperatures that slow but never stop bacteria. A fortnightly quick wipe plus a deeper clean every couple of months keeps it fresh.

Step by step: the deeper fridge clean

1. Turn the fridge off at the wall or set it to the lowest setting, then empty it. Group food on the bench and toss anything past its prime.
2. Remove shelves and drawers. Let glass shelves come to room temperature before they meet warm water, as a sudden temperature change can crack toughened glass.
3. Wash removable parts in the sink with warm water and a few drops of a gentle plant based cleaner. Rinse and let them air dry while you do the interior.
4. Wipe the interior walls, door and ceiling with a damp microfibre cloth and a light dilution of cleaner. Work top to bottom so drips fall onto areas you have not done yet.
5. Pay attention to the door seal (gasket). Run a damp cloth into the folds, where crumbs and mould love to settle. Do not soak it, as a waterlogged seal can perish faster.
6. Wipe everything down a second time with a clean cloth and plain water so no cleaner residue remains. Dry with a fresh cloth.
7. Refit dry shelves and drawers, restore the temperature, and return the food once the fridge is cold again.

Dealing with fridge smells

Odour is usually a sign of a spill you missed or food that has turned. Cleaning the source fixes most of it. For lingering smells after a clean, an open container of bicarb soda on a shelf absorbs odours over a day or two. Avoid masking a smell with heavy fragrance: if it still smells, something still needs cleaning. The Fragrance Free option suits anyone who would rather have no scent at all near stored food.

When this is not the right fix: a fridge that smells musty and runs warm may have a drainage or seal fault rather than a cleaning problem. If wiping does not solve it and food spoils quickly, check the door seal closes flush and consider a service call.

How to clean a microwave without scrubbing

Microwave grime is mostly steam splatter that has dried in place. The smart move is to soften it with steam before you wipe, so you barely scrub at all.

1. Half fill a microwave safe bowl with water and add a slice of lemon or a splash of vinegar.
2. Heat on high for three to five minutes until the window fogs with steam. Leave the door shut for two more minutes so the steam keeps working.
3. Carefully remove the bowl (it will be hot), then wipe the roof, walls and door with a damp microfibre cloth. Softened splatter lifts with almost no pressure.
4. Take out the glass turntable and wash it in the sink. Wipe the ring and the recess underneath, which collects crumbs.
5. For any stubborn spots, dampen a cloth with a little diluted cleaner, wipe, then go over the surface once more with plain water so nothing is left behind. Dry the door and finish the glass window streak free.

Never use abrasive pads or scouring powder inside a microwave: they scratch the interior coating, and on the door window they can compromise the surface that keeps microwaves contained. Gentle always wins here.

How to clean an oven, range hood and cooktop

The oven is the heavy duty job, and honesty matters: a plant based everyday cleaner is brilliant for routine maintenance and the glass door, but carbon that has baked and carbonised over months is a different beast. The goal of regular cleaning is to make sure you almost never reach that point.

Routine oven maintenance

If you wipe the oven floor and walls while they are still slightly warm (not hot) after cooking, fresh grease comes away easily with a damp cloth and a little cleaner. Doing this often is the single best way to avoid ever needing a caustic oven product. Remove racks and soak them in the sink or bath with warm soapy water, then scrub with a soft brush before rinsing and drying.

Self cleaning and pyrolytic ovens

Many newer ovens have a pyrolytic or self cleaning cycle that heats the cavity to a very high temperature and turns residue to fine ash you simply wipe out once cool. If your oven has this, follow the manual: remove the racks first unless the maker says otherwise, ventilate the kitchen well, and keep children and pets clear while the door is hot. A self clean cycle handles the deep carbon, and an everyday cleaner is what you use in between cycles to keep the glass and the cooler surfaces fresh so you run that intense cycle far less often.

The oven door glass

The inside of the oven door glass is where a streak free cleaner shines. Spray a cloth (not the glass directly, to keep liquid away from the vents), wipe the softened residue, then buff dry for a clear, smear free finish. This is the same streak free performance you want on the microwave window and the splashback, and it is covered in more depth in our guide to streak free glass and mirrors.

Range hoods and filters

The range hood is the appliance people forget, yet it collects the most grease of all because its whole job is to pull cooking vapour through itself. Wipe the underside and the painted or stainless canopy with a damp cloth and a greasier dilution of cleaner, working with the grain on any stainless. The metal mesh filters are the real task: slide them out and soak them in a sink of hot water with a good squeeze of cleaner for fifteen to twenty minutes, which lets the enzymes and surfactants loosen the trapped fat, then brush, rinse and dry them before refitting. Many mesh filters are also dishwasher safe on a hot cycle. If your hood uses a charcoal or carbon filter for recirculation rather than mesh, that type cannot be washed and is replaced on the maker's schedule. Aim to degrease the filters monthly if you cook often, and you will keep airflow strong and the kitchen smelling clean.

Cooktops

On a glass or ceramic cooktop, wipe spills as soon as the surface is cool. A diluted cleaner on a cloth lifts everyday marks, and a dedicated ceramic scraper (held flat) removes burnt sugar without scratching. On gas cooktops, lift off the trivets and burner caps and soak them, then wipe the enamel base with a damp cloth. On induction cooktops, the glass stays cooler so spills wipe away easily, but still avoid abrasive pads that can dull the surface over time.

When this is not the right fix: for thick, blackened, carbonised build up inside an oven that has been neglected for a long time, an everyday cleaner will not cut it in one pass. That job calls for repeated gentle treatment over a few sessions, a self clean cycle if your oven has one, a dedicated oven product used with ventilation, or a professional clean. Do not expect a plant based concentrate to dissolve hardened carbon instantly. It is not what it is designed for.

Stainless steel fronts: fingerprint free without the streaks

Stainless steel is the surface people most often get wrong, usually because they treat it like glass. Stainless has a grain (a faint directional brushing) and it shows fingerprints, water spots and cloudy streaks the moment you wipe across that grain or leave residue behind.

The method that works every time

1. Find the grain. Look closely and you will see fine lines running either horizontally or vertically across the panel.
2. Wipe with a damp microfibre cloth and a light dilution of cleaner, always moving in the direction of the grain, never across it or in circles.
3. Follow immediately with a second clean, dry microfibre cloth, again with the grain, to buff away any moisture before it can spot.
4. For handles and the high touch zone around them, a slightly damp cloth lifts the oils from fingertips that cause most of the smudging.

The reason a low residue, plant based cleaner suits stainless is that residue is the enemy of a fingerprint free finish. Oily polishes can look great for a day, then attract dust and show every new print. A clean wipe with the grain and a dry buff gives a more honest, longer lasting result, and you do not need a separate stainless product. There is more on this in our guide to cleaning stainless steel surfaces.

Small benchtop appliances

The little machines collect more grime than people expect, partly because they live out on the bench in the splatter zone. The table below sets out where to focus on each and the one tip that matters most.

The unifying rule for small appliances: unplug first, never submerge the part that holds the motor or heating element, and keep moisture out of vents, slots and electrical contacts. A damp cloth, wrung well, is almost always enough for the outside.

How to clean a dishwasher (and the laundry pair that lives nearby)

It sounds odd to clean a machine whose job is to clean, but both the dishwasher and the laundry pair build up residue, grease and biofilm that eventually cause smells and poor results. The washer and dryer are technically laundry appliances, yet in plenty of homes they sit just off the kitchen and run on the same cleaning rhythm, so they are worth a mention here.

Dishwasher

Pull the filter at the base, rinse it under the tap and scrub it gently with an old brush, as a clogged filter is the most common cause of cloudy dishes and odour. Wipe the door edges and the rubber seal, where grime gathers, and clean the spray arm holes if they look blocked. Run an empty hot cycle periodically to flush the system. Keep the rinse aid topped up for spot free drying, and if you live in a hard water area, dishwasher salt helps the machine soften the water and protects the internals. Wipe the front and controls last for a clean finish.

Washing machine

Front loaders especially trap moisture in the door gasket, which leads to that musty smell. Wipe the rubber seal dry after washes, peeling back the folds to clear any trapped lint or grime, leave the door ajar between loads, and clean the detergent drawer, which gets sticky. Run a maintenance hot wash or a dedicated drum clean cycle now and then to clear detergent residue and biofilm from the drum and hidden pipework. Wipe the exterior and dispenser with a damp cloth and a little cleaner.

Material cautions worth knowing

A versatile plant based cleaner is gentle on most appliance surfaces, but a few materials reward a little extra care. On sealed stone benchtops near your appliances, skip anything acidic, as repeated acid contact can dull the seal over time, and our guide to cleaning sealed stone benchtops safely covers this in detail. Bare aluminium, such as some air fryer baskets or older trays, can discolour if left in contact with strong alkaline or acidic solutions, so wash, rinse and dry it promptly. Anodised and coated finishes, including many non stick interiors, last longest with soft cloths and gentle cleaners rather than scourers or harsh chemicals. When in doubt, test on a small hidden area first and keep abrasives away from glass, coatings and brushed metal.

Choosing one cleaner for the whole job

The appeal of a single, well made concentrate across an appliance clean is that it removes the guesswork about what is safe near food and what will streak the glass. HomeKind is plant based and enzyme activated, with protease, amylase and lipase enzymes that help break down protein, starch and grease, the three messes appliances accumulate most, and it stays streak free on glass so the same bottle handles the oven door, the microwave window and the splashback. It is septic and greywater safe, which matters when rinse water from your fridge or oven goes down the sink, and it comes in four scents on one formula, including a Fragrance Free option for anyone who prefers no scent near food.

One 1L concentrate of the HomeKind All in One Cleaner Concentrate makes up to 100 standard spray bottles, which works out to roughly 40c a bottle versus around five to seven dollars for a typical supermarket spray. A single bottle is $39.99, with bundles at two for $70 or three for $95, and you can mix scents across a bundle. It is made without synthetic dyes, phosphates, parabens or SLS, is not tested on animals, and ships in a recyclable bottle. HomeKind is in stock now: order today and it is posted same day if you order before 1pm, otherwise the next business day. The people behind it clean for a living, so the formula was shaped by the kind of real appliance grime professionals face every day.

A quick honest note: no single product is magic. For hardened oven carbon, heavy limescale or a faulty seal, the right fix is a specialist product, a descaler or a service. For the everyday in and out appliance clean that keeps your kitchen fresh, one versatile concentrate genuinely does cover it. If you want to understand the enzymes doing the heavy lifting, see how enzyme cleaners work, and for tank and septic homes there is more in our note on septic and greywater safe cleaning.

A simple appliance cleaning rhythm

You do not need to do everything at once. The easiest way to keep appliances clean is a light, regular rhythm rather than rare deep cleans.

• Weekly: wipe stainless fronts and handles with the grain, quick wipe the microwave interior, empty the toaster crumb tray.
• Fortnightly: quick fridge interior wipe, clean the dishwasher filter, wipe the cooktop properly.
• Monthly: deeper fridge clean, descale the kettle, degrease the range hood filters, maintenance hot wash in the dishwasher and washing machine.
• As needed: oven door glass when it clouds, self clean cycle when carbon builds up, air fryer basket after messy cooks.

Keep one cloth for cleaning and one dry cloth for buffing within reach, and most of these jobs take a couple of minutes. The appliances that get a small, frequent wipe are the ones that never reach the dreaded crusted stage. For the rest of the house, our room by room cleaning guides apply the same little and often thinking to every space.
