TL;DR
High dusting comes first in any room, because everything you dislodge above eye level lands on the surfaces below. Do it with an extension tool from the floor wherever possible, and use a proper step ladder rather than a chair when you cannot. Kitchen cabinet tops need a degreaser rather than a duster, because that deposit is grease-bound and dry tools only smear it.
What high dusting means
High dusting is the pass that covers everything above normal reach: the tops of cabinets and door frames, crown molding, ceiling fans, light fixtures, wall vents and returns, ceiling corners, and the upper edges of window frames.
These surfaces get skipped for months because nobody sees them, which means the deposit is thick when you finally get to it. That is exactly why the sequence matters -- see the dusting order that stops resettling. High dusting is always step one.
What is the right way to high dust a room?
Start at the highest point and work down, using an extension tool from the floor when you can. Cover or move what is below first, since a heavy deposit will fall. Use capture tools that hold dust rather than fling it, and finish the room with the floor so everything you dropped gets picked up.
Ladder safety comes before technique
More people are hurt reaching for a cabinet top than by any cleaning chemical in the house. This part is not optional.
Use a step ladder, not a chair. Chairs are not designed for standing, especially not on a hard floor, and rolling office chairs are dangerous.
Set it on level, dry ground. Wet floors and thresholds are how ladders slide.
Keep three points of contact. Two feet and a hand, or two hands and a foot. Do not carry a full caddy up a ladder.
Do not stand on the top step or the top cap. If you need that height, you need a taller ladder or an extension tool.
Do not lean sideways. Move the ladder instead. Overreaching is the most common way people fall.
Work with someone home. If you live alone, tell someone you are doing it. Very high ceilings, stairwell landings, and vaulted spaces are worth handing to a professional with the right equipment.
Extension tools do most of the job
An extendable pole with interchangeable heads removes most of the ladder work.
A microfiber duster head handles cabinet tops, molding, and door frames. A lambswool head is good for light fixtures and irregular shapes. A flat microfiber pad on a pivoting frame reaches wall corners and the tops of tall furniture. A vacuum wand extension is the best option for vents and anything you want removed from the room rather than dropped onto the floor.
Extend only as far as you can control. A long pole with a loaded head gets heavy fast, and a wobbling head scrapes paint.
Kitchen cabinet tops are a different job
The film on top of kitchen cabinets is not plain dust. It is cooking grease aerosol that drifted up and then trapped dust in a sticky layer, and a duster will only push it around.
Treat it as a degreasing job. Vacuum the loose material first with a brush attachment. Then apply a degreasing cleaner to a cloth -- not sprayed into the air above your head -- and let it dwell a moment before wiping. Work in sections, rotating to a clean cloth face, and rinse with a damp cloth so no residue remains.
Very heavy buildup may need two passes. If the cabinet finish is delicate or unsealed, test a hidden spot first. Never mix cleaners in a bucket while you are up a ladder, and never combine bleach with anything containing ammonia, acid, or alcohol.
Vents, returns, and light fixtures
Wall and ceiling vents belong in the high dusting pass. Vacuum the grille with a brush attachment rather than wiping it, because wiping pushes dust through the louvers and into the duct. The full method is in cleaning vent covers and registers.
Light fixtures and fans hold the heaviest single deposits in most rooms, and they sit directly above furniture and beds. Cleaning ceiling fans and light fixtures covers doing it without showering the room. Let hot bulbs cool before touching a fixture, and turn the switch off.
Textured ceilings need a lighter hand
A popcorn or textured ceiling sheds if you press on it. Use a vacuum brush attachment held just off the surface, or a very light touch with a dry duster, and never a damp tool.
Older textured ceilings in some homes may contain materials that should not be disturbed at all. If you are unsure about the age or composition of a ceiling, do not sand, scrape, or wet it -- see dusting a popcorn ceiling safely and get it identified before doing anything aggressive.
Order of operations for a high dust pass
- Move or cover what is below -- beds, dining tables, electronics.
- Ventilate if the outdoor air is reasonable.
- Ceiling corners and light fixtures.
- Fan blades, top edge first.
- Crown molding and cabinet tops.
- Wall vents and returns, vacuumed not wiped.
- Door frames and the tops of doors.
- Window frame tops and blind headrails.
- Then everything below, and the floor last.
How often
Twice a year covers most high dusting in a normal home. Kitchen cabinet tops usually need three to four passes a year because grease keeps accumulating. Vents and returns do better quarterly, and homes with pets or forced-air heat need the shorter interval throughout.
FAQ
How often should you high dust a house?
Twice a year covers most high surfaces in a normal home. Kitchen cabinet tops usually need three or four passes because grease keeps building, and wall vents do better on a quarterly schedule. Homes with pets or forced-air heat generally need the shorter interval everywhere.
What is the best tool for dusting high places?
An extendable pole with interchangeable heads does most of the work from the floor: a microfiber duster head for flat surfaces, lambswool for fixtures, and a vacuum wand extension for vents. Extension tools remove most of the ladder time, which is the riskiest part of the job.
How do you clean greasy dust off the top of kitchen cabinets?
Vacuum the loose material first, then apply a degreasing cleaner to a cloth rather than spraying overhead, let it dwell briefly, and wipe in sections. Follow with a damp cloth to remove residue. Dry dusters only smear grease-bound dust around, so degreasing is the necessary step.
Is it safe to stand on a chair to reach a cabinet top?
No. Chairs are not designed for standing, they tip easily on hard floors, and rolling chairs are especially dangerous. Use a step ladder set on level dry ground, keep three points of contact, and never stand on the top step or lean sideways to extend your reach.
Should high dusting come before or after everything else?
Before. Anything you dislodge above eye level lands on the surfaces below, so high dusting is step one and the floor is the final catch. Cleaning low surfaces first means doing them twice, since the high pass will drop debris on everything you just finished.
How do you dust a textured or popcorn ceiling?
Very gently, and dry only. Use a vacuum brush attachment held just off the surface or a light dry duster. Never use a damp tool, and never scrape or sand. Older textured ceilings can contain materials that should not be disturbed, so have unknown ones identified first.
High surfaces, vents, and ceiling work are where most home routines quietly fall behind, and tall or vaulted spaces need equipment most households do not own. If you would rather hand off the seasonal passes, get a quote or read more about house cleaning services.
