Deep clean a bedroom from the top down: strip the bed and get the laundry going first, dust from the ceiling fan downward, do windows and furniture, clean under the bed and the mattress, and vacuum the floor last so it catches everything you knocked down. Plan on an afternoon, a few times a year. The weekly jobs stay weekly.
Before you start#
Clear the decks so you're cleaning, not tidying. Take in a laundry basket, a trash bag, and a box for things that live in other rooms, and fill them fast. Don't start sorting the wardrobe or a drawer of old cables. That's a different project, and it will eat the afternoon.
Then strip the bed and start the first wash before you do anything else. Sheets, pillowcases, and the mattress protector take the longest of anything here, and you want them dry by the time the room is done.
If you're going to pull a dresser or bookcase away from the wall to clean behind it, check whether it's anchored. The CPSC's Anchor It campaign recommends securing all furniture with drawers, doors, or shelves to the wall to prevent tip-overs, and if you have young children, the day you're moving furniture anyway is a good day to fit the straps.
The checklist, in order#
Work top to bottom and around the room once, clockwise or counterclockwise. Dust falls, so anything you clean low before high gets dusty again.
1. Ceiling and high spots#
- Ceiling fan blades (see how to clean a ceiling fan; the pillowcase trick keeps the dust off your bed)
- Light fixtures and lampshades, with the lamps switched off and cool
- Tops of the wardrobe, door frames, and curtain rails
- Corners of the ceiling for cobwebs
- Air vents and the smoke alarm cover
Use a dry microfiber cloth or a barely damp one. The NHS advice on allergic rhinitis suggests dusting with a damp cloth, which traps dust instead of sending it into the air.
2. Windows, blinds, and curtains#
- Blinds, slat by slat (how to clean blinds)
- Curtains: wash or vacuum them, depending on the fabric
- Window glass, sills, and tracks
- Look at the bottom corners of the window frame. Black spots there usually mean condensation is sitting overnight.
3. Furniture and surfaces#
- Empty the nightstand tops and wipe them down
- Wipe drawer fronts and handles, then light switches and the door handle
- Vacuum an upholstered headboard with the brush attachment, paying attention to buttons and seams
- Clean mirrors and any glass
- Wipe the TV and electronics with a dry cloth only
4. The mattress and bed frame#
With the bed stripped, vacuum the mattress on low with a brush attachment, then treat any stains. The mattress cleaning guide covers stains, baking soda, and whether you can rotate or flip yours. Vacuum the bed frame and slats, and tighten any bolts that have worked loose and started squeaking.
5. Under the bed and behind furniture#
This is the part that makes it a deep clean. Pull out everything stored under the bed, wipe the boxes, and vacuum the whole space. Do the same behind the nightstands and dresser. Skirting boards or baseboards come next, with a damp cloth.
While you're down there, sniff. A musty smell under the bed or in a wardrobe corner points to moisture, and moisture needs fixing, not cleaning.
6. Floors, last#
- Vacuum slowly, including edges and under the radiator
- Carpet and rugs: see how often to clean carpet for when it's time for a deeper clean
- Hard floors: mop after vacuuming
For allergy households, the Asthma and Allergy Foundation of America's dust mite guidance recommends vacuuming weekly with a HEPA-filter vacuum and cutting clutter, since dust settles on everything you keep out on surfaces.
7. Air it out and remake the bed#
Open the window while the bedding dries. Only remake the bed when every layer is completely dry, the protector included.
How often to clean each part of a bedroom#
A deep clean only stays done if the smaller jobs keep happening between them. This is the rhythm IKEA suggests in its bedroom cleaning guide, plus the deep clean on top:
| How often |
Job |
| Weekly |
Wash bed linen, vacuum, shake out the rug |
| Monthly |
Wash the mattress protector, air the duvet |
| Every 3 to 6 months |
This full checklist; wash pillows |
| Every 6 months |
Rotate or flip the mattress if allowed; swap seasonal duvets |
What to do about condensation and musty smells#
Bedrooms get a lot of moisture from breathing alone, and it collects on cold windows overnight. The EPA's guide to mold and moisture recommends keeping indoor humidity below 60%, ideally between 30% and 50%. A cheap hygrometer on the nightstand tells you where you stand. If condensation keeps coming back on the same windows, or mold reappears soon after you clean it, deal with the moisture source: ventilation, a dehumidifier, or a leak.
Note anything that needs a repair instead of a clean, like a loose bed frame, a broken blind, or a drafty window, and add it to a separate list. Then put the next deep clean in ChoreLists.com for three months out, so the under-the-bed dust doesn't get a year's head start.
