How fast does it build up?
Everyone has a job they’re not sure how often to do. The oven, say. Once a month feels like too much, and once a year feels like a confession.
A cleaning schedule is a set of answers to one question: how fast does this build up? For the things that touch health, the agencies have already answered it. Dust mites live in bedding and feed on the skin you shed every day, so the Asthma and Allergy Foundation of America and the CDC both say wash sheets weekly, in water of at least 130°F, and vacuum weekly with a HEPA filter (AAFA, CDC). Mold needs moisture and time, so the CDC says dry anything wet within 24 to 48 hours. The FDA says clean the refrigerator regularly, wipe spills right away and keep it at or below 40°F (FDA). Baseboards and vents collect dust slowly, so they can wait for a season.
Most people already run a version of this. On an average day in 2025, 36% of Americans did housework such as cleaning or laundry, according to the Bureau of Labor Statistics. The ones who did spent about an hour and a half on it. The schedule below is about spending that time where it counts, and giving the oven a date.
Every week, room by room
The weekly list is the floor, in both senses. Room by room, this is what a thorough regular pass covers.
- Kitchen. Wipe counters and backsplash. Clean the sink and tap. Wash the dishes in the sink. Wipe the outside of appliances. Sweep and mop the floor. Empty the bin.
- Each bathroom. Clean and disinfect the toilet. Clean the sink and mirror. Clean the shower or tub. Sweep and mop the floor. Empty the bin.
- Each bedroom. Strip the bed and wash the sheets hot. Dust surfaces with a damp cloth. Vacuum the floor, including under the bed. Empty the bin.
- Living area. Dust surfaces. Vacuum the floor and the sofa. Tidy and straighten.
- Entry. Sweep or vacuum. Shake out the mat.
If you have a pet or anyone with asthma at home, the CDC recommends vacuuming with a HEPA filter and keeping pets out of bedrooms.
The jobs you notice too late
Monthly jobs are the ones you notice only when they slip, usually while a guest is opening your microwave.
- Clean inside the microwave.
- Wipe the refrigerator shelves and door seals, and throw out anything past its date. Wipe spills the day they happen, as the FDA advises, so this stays a 10-minute job.
- Wash bath mats, hand towels you haven’t rotated, and the shower curtain liner.
- Vacuum under and behind furniture you can move. Empty or wash the vacuum’s filter.
- Wipe light switches, door handles, the fridge handle and the remote.
- Descale the kettle and the showerhead if your water is hard.
- Check indoor humidity. The CDC and the allergy foundation put the target at 30% to 50%.
Each season, the edges
Every 3 months, clean the dust that settles where your weekly routine doesn’t reach. A seasonal deep clean includes the weekly list plus the edges of every room: baseboards and door frames, vents and vent covers, and the insides the weekly pass skips.
- Baseboards, door frames and the tops of door casings.
- Vents, vent covers and the return grille. Change the furnace filter if it’s due.
- Inside windows, sills and tracks. Blinds, slat by slat, with a damp cloth.
- Curtains, duvets, pillows and mattress protectors, washed as their labels allow.
- The oven interior and the range hood filter.
- Closets: floor vacuumed, shelves wiped, anything unworn for a year set aside.
Two of these are worth tying to the calendar. One before the heating season, so the dust in the vents doesn’t blow around the house in November. One after pollen season, which on the Front Range runs into October; Denver’s dry air and dust explains why. In a Denver home, the first cold week is often when the vents give themselves away.
Once or twice a year
- Empty and wash the inside of the fridge and freezer, and pull the unit out to vacuum the coils.
- Empty and wipe the inside of kitchen cabinets and drawers.
- Wash walls where hands land: around switches, along hallways, behind the bin.
- Clean the garage floor and the space under the stairs.
- Clear the whole dryer vent run, lint trap included.
Whenever you bring out strong products for any of this, the EPA’s advice applies: open windows, follow the label, buy only what you need and never mix products unless the label says to (EPA).
The whole thing on one page
| Rhythm | What it covers | Why then |
|---|---|---|
| Weekly or every 2 weeks | Kitchen, every bathroom, every bedroom, living area, entry: the weekly list above | Dust mites, food spills and bathroom moisture build up within days |
| Each season | The weekly list plus baseboards, vents, door frames and the inside of the microwave in every room | Settled dust is stirred up when the heating or cooling starts |
| Moving | Inside every cabinet, closet and appliance, the fridge, the oven, the garage | An empty home has no insides to hide; the move-out checklist has the list |
| After hosting | Kitchen, bathrooms, floors, trash out | The debris from one evening, before it sets |
The fridge, the oven and the cabinets don’t need a season of their own. Attach one to each seasonal pass in rotation: the oven this quarter, the fridge next, the cabinets after that. The once-a-year list gets done without a day set aside for it, and the oven finally has a date. It’s sooner than you think, and later than you feared.
