A deep cleaning checklist covers everything a standard clean touches, plus everything it skips: inside the oven and fridge, the greasy film on the range hood, grout lines, baseboards, window tracks, vents, light fixtures, and the floor behind the couch. Work top to bottom, back to front, one room at a time, and a typical three-bedroom house takes one long day solo — or an afternoon with help.
What follows is the actual room-by-room deep cleaning house checklist our teams work from, refined across more than 1,200 Puget Sound homes since 2022. Use it straight, or skim it to decide which rooms you'll tackle yourself and which are worth handing to a professional deep cleaning crew.
One honest note before you start: a real deep clean is physical. Budget more time than you think, put on a long playlist, and don't try to do the whole house in one Saturday if it hasn't had a reset in over a year.
Deep cleaning vs standard cleaning: what actually changes
A standard clean maintains. It handles the surfaces you touch every day — counters, floors, bathrooms, dusting — and it assumes the home was in good shape to begin with. A deep clean resets. It goes after buildup: grease that has migrated onto cabinet fronts, soap scum fused to shower glass, dust packed into vents and window tracks, and the grime line where the baseboard meets the floor.
| Task | Standard clean | Deep clean |
|---|---|---|
| Baseboards & door frames | Spot-dusted | Hand-wiped end to end |
| Inside oven & fridge | Not included | Emptied, scrubbed, deodorized |
| Range hood & backsplash | Quick wipe | Fully degreased, filter washed |
| Grout & caulk lines | Surface-cleaned | Scrubbed, mildew-treated |
| Window tracks & blinds | Skipped | Vacuumed and washed |
| Behind & under furniture | Skipped | Moved, vacuumed, mopped |
When is it worth it? Any home that is new to you. Any home about to start a recurring cleaning schedule — a deep clean first means the weekly pass actually keeps up. After an illness, before hosting, when allergies flare, and at least once a year for everyone else. In our damp marine climate, buildup happens faster than most people expect.
The room-by-room deep cleaning checklist
Three rules keep this from taking twice as long. Work top to bottom, because dust falls. Work back to front, so you never walk across a clean floor. Finish one room before starting the next — half-done rooms are how deep cleans die on a Saturday afternoon. Load your supplies into a caddy or bucket so everything travels with you.
Kitchen deep cleaning
The kitchen is roughly a third of the whole job, so start here while you have energy. Grease travels — it settles as a thin film on cabinet fronts, the top of the fridge, and light fixtures, and it needs dish soap or a degreaser, not just a damp cloth. Start the slow jobs first: coat the oven interior with a baking soda paste, and tie a vinegar-soaked cloth around the faucet to dissolve mineral scale while you work the rest of the room.
- Empty the fridge, toss expired food, wash shelves and drawers in warm soapy water
- Clean the oven interior — a baking soda paste left to sit beats fume-heavy sprays
- Degrease the range hood, wash its filter, and scrub the backsplash
- Wipe cabinet fronts and hardware top to bottom — grease film loves the upper doors
- Pull the fridge and stove out if they move; vacuum and mop underneath
- Descale the faucet with a vinegar-soaked cloth, then scrub and disinfect the sink and drain
- Clean the dishwasher filter and run an empty hot cycle with a cup of vinegar
- Steam-clean the microwave (a bowl of water and lemon for two minutes), then wipe inside and out
- Wipe down small appliances — toaster crumb tray, coffee maker, kettle
- Dust the top of the fridge and upper cabinets — expect a sticky film, not just dust
- Wash the trash can inside and out, plus the wall behind it
- Wipe switch plates, door handles, and chair backs
- Vacuum and mop last, getting the edges and under the toe kicks
Bathrooms
Seattle-area bathrooms grow mildew faster than most — our marine air stays damp for much of the year, and a poorly vented bathroom never fully dries out. Spray the tub, shower walls, and grout first and let everything sit ten minutes before you scrub. That dwell time is most of the battle.
- Spray tub and shower, wait ten minutes, then scrub — soap scum wipes off instead of fighting back
- Scrub grout lines with an oxygen-bleach paste and a stiff brush
- Treat mildew along caulk lines and corners; if it lives under the caulk, plan to recaulk
- Strip hard-water film off glass shower doors, then squeegee dry
- Descale the showerhead and sink faucet
- Vacuum and wash the exhaust fan cover — packed dust chokes airflow and feeds mildew
- Clean the toilet completely: bowl, seat hinges, base, and the wall behind it
- Empty and wipe vanity drawers; toss expired products
- Machine-wash bath mats, shower curtain, and liner
- Wipe mirrors, light fixtures, switch plates, and door handles
- Vacuum and mop the floor, including behind the toilet
Bedrooms
Bedrooms are mostly a dust-and-textiles job, and it matters more than it looks: this is where you spend eight hours a night breathing, and mattresses and under-bed zones are where dust and allergens concentrate. Strip the bed first so the laundry runs while you clean.
- Strip the bed; wash duvet covers, pillow protectors, and mattress pads — not just sheets
- Vacuum the mattress on both sides and rotate it
- Vacuum under the bed and pull nightstands out to clean behind them
- Dust ceiling fan blades, light fixtures, and the tops of door frames
- Hand-wipe baseboards and door faces
- Clean window tracks and sills; wash blinds or vacuum curtains with the brush head
- Clear and wipe nightstand and dresser tops, plus mirrors and switch plates
- Edge-vacuum with the crevice tool, then vacuum the full floor
Living areas
This is baseboard-and-vent territory — the slow, unglamorous work that makes a deep clean visible. One caveat on carpet: a deep clean gets the surface and the edges, but ground-in soil lives deeper in the fibers than any vacuum reaches. That takes hot-water extraction, which is a separate job with separate equipment.
- Move the couch and chairs; vacuum and mop underneath and behind
- Vacuum upholstery, including under and behind the cushions
- Hand-wipe baseboards end to end
- Vacuum air vents and returns; wash the covers if they are grimy
- Dust light fixtures, lamps, and ceiling fan blades
- Wash blinds slat by slat, or vacuum curtains top to bottom
- Clean window tracks, sills, and interior glass
- Dust the TV, electronics, and the cable tangle behind the console
- Wipe door handles, switch plates, and stair rails
- Edge-vacuum along the baseboards, then vacuum and mop the floor
Entry, mudroom, and laundry
Around Puget Sound, mud season runs roughly October into May, and every bit of it comes through the front door. The entry takes twenty minutes and changes the first impression of the entire house. While the entry mats are in the wash, give the laundry machines themselves a pass — the washer gasket is one of the moldiest spots in any PNW home.
- Shake out and machine-wash entry mats and runner rugs
- Clear the shoe pile; vacuum and mop the grit underneath it
- Wipe the front door, frame, threshold, and handle inside and out
- Erase scuffs on walls and trim with a damp melamine sponge
- Scrub the washer door gasket, then run an empty hot cycle
- Clean the dryer lint screen and vacuum the slot it sits in
- Wipe the tops of the washer and dryer and sweep behind them if they slide out
- Vacuum and mop the entry floor last, once the mats are dry
How long does a deep cleaning take?
The honest answer: longer than you think, and it scales with square footage and how long it has been since the last reset. Here is what we see across the homes we clean — DIY hours for one person working the full deep cleaning list above, next to what a trained two-person crew takes.
| Home size | DIY (one person) | Pro crew of two |
|---|---|---|
| Studio / 1-bed apartment (~700 sq ft) | 4–6 hours | 2.5–3.5 hours |
| 2-bed home (~1,100 sq ft) | 6–8 hours | 3–4.5 hours |
| 3-bed home (~1,800 sq ft) | 8–12 hours | 4–6 hours |
| 4-bed+ home (2,500+ sq ft) | 12–16+ hours | 5–8 hours |
Add 20–30% if it has been more than a year since the last deep clean, or if pets share the home.
Why are crews so much faster? Not magic — repetition. A team that has run this list a thousand times splits rooms, sprays every wet zone the minute they walk in so products dwell while they work elsewhere, and never doubles back over a finished floor. You can borrow all three habits for free.
Deep cleaning supplies: the short list
You do not need a cabinet full of specialty sprays. Most of this list runs on four kinds of chemistry — an acid for mineral scale, a degreaser for the kitchen, an abrasive for scrubbing, and an oxygen bleach for grout — plus good cloths and patience. This kit is close to what our own crews carry, and everything on it has an eco-friendly, pet- and kid-safe version.
- White vinegar — descaling faucets, showerheads, and hard-water film
- Baking soda — oven paste, sink scrub, deodorizing
- Plain dish soap — the best degreaser already in your house
- Oxygen-bleach powder — grout and caulk without the chlorine fumes
- 10–12 microfiber cloths, plus two reserved for glass only
- Non-scratch sponges and a melamine sponge for scuffs
- Stiff grout brush plus an old toothbrush for tight corners
- Vacuum with crevice tool and brush head — HEPA if allergies are a factor
- Flat mop with washable pads — string mops push dirty water around
- Rubber gloves, a plastic putty knife for baked-on drips, and a step stool
How often should you deep clean a house?
Once or twice a year is the baseline. Around here we push for twice: a late-fall pass, because the wet season seals the house up and mildew gets to work, and a spring reset once the mud finally lets up. Homes with shedding pets, allergy sufferers, or small kids do noticeably better on a quarterly rhythm.
The other half of the answer: a deep clean holds much longer when something maintains it. Homes on a regular weekly or bi-weekly schedule rarely need more than one true deep clean a year, because the buildup never gets a head start.
How much does a deep cleaning cost?
In the Seattle area, most one-time deep cleans run $300 to $600 for an average-size house, with square footage and condition doing most of the work on the price. Small apartments come in lower. Add-ons like inside-oven, inside-fridge, and interior windows are what usually push a quote up — which is exactly why they are already on the list above.
Our deep cleans are part of home cleaning, which starts at $149, and every quote is flat — scoped up front, no hourly meter running while someone scrubs your grout. You can get a flat quote in about 60 seconds, and first-time clients save $40. For the full numbers — standard vs deep vs recurring, and what moves the price — see our Seattle-area pricing guide.
When to hand it to a crew
Do the math on your own weekend. If the table above says 10 hours and your Saturdays are worth more than that, a crew is the cheaper option — especially when the list has grown past what one person can face. Moving is its own case: an empty-home clean has different priorities, and our move-out cleaning checklist is built around the items landlords actually grade on the final walkthrough.
If you would rather hand over the whole list, that is literally what our deep cleaning service is — this checklist, run by a background-checked, bonded and insured team that works it every week across King, Snohomish, and Skagit counties, backed by a 100% satisfaction guarantee. Either way, print the list. It works.
