How to Clean Kitchen Appliances properly is a skill most of us pick up only after something goes wrong — the oven starts smoking, the fridge develops a smell, or the dishwasher leaves dishes cloudy. Appliances collect grease, food residue, and bacteria in places you cannot see: behind the fridge, inside the oven door, under the microwave plate, and inside drain filters. Regular cleaning keeps them working efficiently, extends their life, and keeps your food safe.
This guide covers the appliances found in most UAE homes: the refrigerator, microwave, oven, dishwasher, stovetop and extractor fan, kettle, and small appliances like toasters and blenders. You will find step-by-step methods, safe cleaning products, common mistakes to avoid, and a maintenance schedule you can actually stick to.
Quick Answer
To clean kitchen appliances, start by unplugging or switching off the appliance and letting it cool. Use hot soapy water and a soft cloth for most surfaces, baking soda paste for baked-on grime, and white vinegar for limescale. Clean the fridge monthly, the microwave weekly, the oven every one to three months, and run the dishwasher empty on a hot cycle monthly. Never spray water directly into vents or electrical parts, and never mix bleach with vinegar or ammonia. For appliance-specific steps, see our guides on cleaning a microwave, cleaning an oven, and cleaning a dishwasher.
How to Clean Kitchen Appliances: Safety First
Before you touch any appliance, follow these rules:
- Unplug small appliances and switch off large ones at the wall before cleaning.
- Let hot appliances cool. Cleaning a hot oven with water or chemicals can cause steam burns or damage the finish.
- Never spray liquid into vents, motors, or control panels. Dampen a cloth instead and wipe around electrical parts.
- Never mix cleaning chemicals. Bleach mixed with vinegar or ammonia releases dangerous fumes.
- Rinse food-contact surfaces — shelves, racks, and interiors — after using any chemical cleaner.
- Check the manual for self-cleaning functions and any warnings about specific parts, especially for ovens and dishwashers.
Refrigerator and Freezer
The fridge is the one appliance you should never neglect, since everything inside it goes into your body. A full clean once a month is ideal:
- Switch the fridge off or set it to a holiday mode if it has one, and move perishable food into a cooler bag with ice packs.
- Remove shelves, drawers, and door racks. Wash them in warm soapy water, rinse, and dry fully.
- Wipe the interior walls and ceiling with a solution of two tablespoons of baking soda in a litre of warm water — this cleans and deodorises without chemicals.
- Scrub the door seals with an old toothbrush and soapy water. Mould and crumbs hide in the folds, and damaged seals let cold air escape.
- Dry everything, replace the shelves, restock the food, and switch the fridge back on. Check that it settles at 4°C or below.
For the freezer, defrost when ice builds up beyond about 5mm (frost-free models handle this automatically), and wipe the interior before switching it back on. Do not forget the back and underside: pull the fridge out twice a year and vacuum the condenser coils, which collect dust and make the compressor work harder. A clean fridge runs cheaper and keeps food at a safer temperature — see how long food can stay in the refrigerator for storage times once your fridge is clean.
Microwave
Microwaves need a quick clean weekly because food splatters harden fast:
- Remove the turntable and roller ring, and wash them in hot soapy water.
- Place a microwave-safe bowl of water with a few lemon slices or a tablespoon of vinegar inside, and run the microwave for 3–5 minutes until the window steams up.
- Let it stand for two minutes, then wipe the interior — roof, walls, and door — with a soft cloth. The steam loosens splatters so you rarely need to scrub.
- Wipe the door seal and the outside, including the handle and keypad.
Avoid abrasive pads inside the microwave, since scratches in the cavity lining can worsen over time. For stubborn smells, leave a bowl of baking soda inside overnight with the door closed. Our full guide to cleaning a microwave covers deep-cleaning and what to do about burnt food.
Oven
Ovens accumulate the toughest grime in the kitchen — baked-on grease and carbonised spills. Clean yours every one to three months depending on how often you cook:
- Remove the racks and soak them in the sink or bathtub in hot water with dish soap or a degreaser for an hour, then scrub.
- Make a paste of baking soda and water, spread it over the oven interior (avoiding the heating elements), and leave it for several hours or overnight.
- Wipe the paste away with a damp cloth, then spritz any remaining residue with vinegar and wipe clean.
- Clean the oven door glass with the same paste or a dedicated glass cleaner. For doors that open between the glass panes, check the manual before dismantling anything.
If your oven has a pyrolytic self-cleaning function, follow the manual exactly — remove racks first and ventilate the kitchen, as the cycle produces heat and some odour. Never use oven cleaner on a self-cleaning oven’s interior coating unless the manual allows it. Full details are in our guide to cleaning an oven.
Dishwasher
A dishwasher cleans your dishes, but it needs cleaning itself — food particles, grease, and limescale build up in the filter and spray arms:
- Remove the bottom rack and take out the filter. Rinse it under hot water and scrub with an old toothbrush.
- Check the spray arms for clogged holes and clear them with a toothpick.
- Place a dishwasher-safe cup of white vinegar on the top rack and run an empty cycle on the hottest setting.
- Wipe the door seal and edges with a damp cloth, where grime collects out of sight.
- Leave the door slightly open after cycles so moisture does not breed mildew.
Run this maintenance monthly. In the UAE, where tap water is hard in many areas, limescale builds up faster — a periodic empty hot cycle helps, and you can learn more about how dishwashers work to understand why the filter matters. Our dedicated guide to cleaning a dishwasher walks through each step in more detail.
Stovetop and Extractor Fan
For gas hobs, remove burner caps and grates weekly and soak them in hot soapy water; scrub with a non-abrasive pad and dry fully before replacing. For glass-ceramic electric hobs, use a dedicated ceramic hob cleaner and a soft cloth — a razor scraper held flat removes burnt-on spots, but check your manual first.
The extractor fan above the stove traps most of the grease. Remove the metal mesh filters monthly and soak them in hot water with a degreaser or dish soap, then scrub with a brush and dry before refitting. Wipe the hood’s exterior with a degreasing spray. A clean filter extracts smoke and odours far better, which matters in apartments where cooking smells linger.
Kettle, Toaster, and Small Appliances
Electric kettle: Descale every one to two months by boiling a mixture of equal parts water and white vinegar, letting it sit for 20 minutes, then rinsing and boiling fresh water twice. Hard water in the UAE makes descaling especially important.
Toaster: Unplug it, remove and wash the crumb tray weekly, and shake crumbs out over the sink. Never stick a knife inside — use a wooden skewer for stuck bread, with the toaster unplugged.
Blender and food processor: Rinse immediately after use so food does not dry onto the blades. Fill the jug halfway with warm water and a drop of dish soap, run it for 30 seconds, then rinse and air-dry. Take the blade assembly apart monthly for a proper wash, handling blades carefully.
Coffee machine: Descale according to the manufacturer’s schedule using descaler or a vinegar solution, and wash the carafe and filter basket after every use.

Cleaning Products That Are Safe for Appliances
- Dish soap and hot water — safe for almost every surface.
- Baking soda — gentle abrasive for ovens, fridges, and sinks; also deodorises.
- White vinegar — dissolves limescale in kettles, dishwashers, and coffee machines.
- Dedicated degreaser or oven cleaner — for heavy grease, used exactly as labelled.
- Microfibre cloths — clean glass, stainless steel, and screens without scratching.
Avoid steel wool and harsh scouring pads on non-stick coatings, glass hobs, and stainless steel — scratches collect grime and are hard to reverse. Do not use bleach inside the microwave or dishwasher, and always rinse thoroughly after any chemical cleaner. When in doubt, the gentlest effective method is the right one.
Common Mistakes to Avoid
- Spraying cleaner directly onto control panels — liquid seeps in and damages electronics. Spray the cloth instead.
- Cleaning a hot oven with cold water — thermal shock can crack glass doors and damage enamel.
- Ignoring the fridge coils — dusty coils make the compressor run longer and use more electricity.
- Using the self-clean cycle with racks inside — the extreme heat can discolour or damage them.
- Forgetting the small parts — filters, seals, and drip trays are where odours and bacteria hide.
Keeping appliances clean is one part of a safe kitchen — it works best alongside good habits like basic food safety rules at home and a regular whole-kitchen routine (see how to keep a kitchen clean).
Frequently Asked Questions (FAQs)
How often should I clean my kitchen appliances?
Microwaves and stovetops need weekly attention, fridges and dishwashers a monthly clean, ovens a deep clean every one to three months, and small appliances a rinse after each use with a monthly deep wash. The table above gives a full schedule.
Can I use vinegar to clean all appliances?
Vinegar is excellent for limescale in kettles, dishwashers, and coffee machines, and for steam-cleaning microwaves. Avoid it on natural stone, cast iron, and some rubber seals, and never mix it with bleach.
Why does my dishwasher smell bad even after a cycle?
The usual cause is a dirty filter or food trapped in the door seal. Remove and scrub the filter, wipe the seal, and run an empty hot cycle with vinegar. Leaving the door ajar between cycles prevents mildew.
Is it safe to use oven cleaner?
Yes, when used exactly as the label instructs — ventilate the kitchen, wear gloves, and keep it away from heating elements and self-cleaning coatings unless the manual allows it. A baking soda paste is a gentler alternative for light to moderate grime.
How do I remove limescale from my kettle in the UAE?
Boil equal parts water and white vinegar, let it stand for 20 minutes, then rinse and boil fresh water twice before use. In areas with hard water, descaling every four to six weeks keeps the kettle efficient and the water tasting clean.
Should I clean behind the refrigerator?
Yes, twice a year. Dust on the condenser coils forces the compressor to work harder, raising electricity use and shortening the appliance’s life. Unplug the fridge, vacuum the coils gently, and wipe the floor underneath before pushing it back.
The Bottom Line
Learning how to clean kitchen appliances is mostly about timing: small, frequent cleans stop grime from hardening into a weekend project. Unplug and cool down first, use gentle products before harsh ones, and keep to the schedule above. Clean appliances run more efficiently, last longer, and — most importantly — keep the food your family eats safe.
