Cleaning the gaps: under appliances, behind radiators, on top of cabinets
Most household dust is not on the surfaces you clean. It is under the fridge, behind the radiator, on top of the wall cabinets and along the skirting behind furniture — places that get cleaned when somebody moves house.
This matters more than tidiness. Dust under a fridge or a freezer sits on the condenser coils, which makes the compressor work harder and run hotter. Dust behind a radiator reduces its output. Both cost money quietly.
The order that works
Top down, always. Anything you dislodge falls, so start with the highest surfaces and finish with the floor. Cleaning the floor first and then the top of the cabinets means doing the floor twice.
- Tops of wall cabinets and wardrobes
- Light fittings, picture rails, curtain tops
- Behind and under radiators
- Behind and under furniture and appliances
- Skirting boards
- Floor
Tools that reach
Flexible gap dusters
A long flat head on a bendable shaft with a washable microfiber sleeve. The only tool that genuinely gets under a fridge or a washing machine, and the only one that goes behind a radiator without removing it. Look for a shaft that holds a bend rather than springing back, and for sleeves that come off and go in the wash.
Extendable dusters
For cabinet tops, ceiling corners and light fittings. A telescopic handle beats standing on a chair, and it is safer.
Vacuum crevice and brush tools
Better than a duster where you can reach, because they remove the dust rather than moving it. The brush attachment is the one for radiator fins and vents.
A damp cloth on a flat mop head
For skirting boards along a long wall. Far quicker than crouching, and it picks up rather than redistributing.
Specific problems
Behind radiators
Put a damp towel on the floor underneath first, then work the duster down between the fins from the top. Anything dislodged lands on the towel. Do this cold — a hot radiator bakes the dust and smells.
Under a fridge or freezer
The grille at the base or the coils at the back. Unplug it first. A brush attachment on a vacuum, then a gap duster along the floor. Twice a year is enough and it measurably helps efficiency.
Tops of kitchen wall cabinets
This is not dust but grease-bound dust, and dry dusting will smear it. Use a degreaser and a cloth, and consider lining the top with a sheet of paper or foil afterwards — next time you replace the liner instead of scrubbing.
Under a washing machine
Do not drag the machine to clean under it — the feet damage vinyl and the drum can be jolted. A gap duster along the floor from the front does the job.
Window and door tracks
Vacuum first, then a stiff brush, then a damp cloth wrapped over a flat tool. Doing it in that order takes a quarter of the time.
Dry or damp?
Dry microfiber holds dust electrostatically and is right for anything that must not get wet — electronics, light fittings, radiator interiors.
Slightly damp microfiber grabs more and does not resettle dust into the air, and it is right for skirting, worktops and cabinet tops. Damp means wrung out hard, not wet.
Never wet anything you cannot see the back of. Water going under an appliance or into a wall cavity is a worse problem than dust.
How often
- Weekly: visible surfaces, floors.
- Monthly: skirting boards, behind accessible furniture, radiator faces.
- Twice yearly: under appliances, behind radiators, tops of cabinets, light fittings.
The twice-yearly list is the one that gets skipped, and it is the one with the measurable benefit.
Looking after the tools
Microfiber sleeves need washing without fabric softener and drying on low heat — softener coats the fibres and heat welds them, and either will stop a duster working. Wash them separately from cotton, which sheds lint onto them.
What we list
Our cleaning tools state the reach, the head thickness and whether the sleeves are washable and replaceable. Head thickness is the figure that decides whether a duster fits under your appliances — measure the gap first, and the rest follows.
Common questions
Does dust under the fridge actually matter?
Yes. It settles on the condenser coils, which makes the compressor work harder and run hotter. Cleaning it twice a year measurably helps efficiency and lengthens the appliance's life.
What order should I clean in?
Top down, always. Anything you dislodge falls, so cabinet tops and light fittings first, then radiators and furniture, then skirting, then the floor.
Dry or damp cloth?
Dry microfiber for anything that must not get wet — electronics, light fittings, radiator interiors. Slightly damp for skirting, worktops and cabinet tops, because it lifts dust instead of putting it into the air.
