The windows have been shut for weeks. Dust settles thicker, cooking film clings to glass, and condensation beads on cold panes every morning. Leave it and you are not looking at dirt — you are looking at mould being scheduled, heating that bakes last year's dust back into the air, and salt and grit ground into every floor from the front door.
This calendar does not reskin spring cleaning for cold weather. It runs winter as it actually works: seal the house and set the air right, do the deep interior jobs the sealed house needs, keep light and dust under control through the darkest months, then reset before spring. Every task answers winter physics — radiators, filters, condensation, short sharp airing, and the door zone — in timed jobs you can tick off as you go.
The short version: 64 tasks, about 11.5 hours in total if you do it in one go — and every task can be ticked off in the checklist above as you finish it. The full list is written out below, so the page still works printed or saved.

Pro Tips
- Air short and sharp, never long and tilted. Ten minutes wide open replaces the room's air while walls stay warm; a window cracked for hours just cools the wall around it and invites condensation.
- Condensation is a cause problem, not a wiping problem. Drying laundry, long showers and covered pans make the water — manage one cause and the morning panes tell you within days.
- Keep furniture a hand's width off cold external walls all winter. Still air behind a wardrobe on a cold wall is exactly where mould starts, unseen until spring.
- Watch the hygrometer, not your feelings. Winter rooms feel dry at the skin while cold corners sit damp — the 40–55% band keeps both problems away at once.
- Salt is a floor finish problem, not just dirt. Rinse the entry weekly in thaw weeks; grit left in place gets walked in and works like sandpaper under every shoe.
Frequently Asked Questions
How is winter cleaning different from fall and spring cleaning?
Fall cleaning prepares the house for winter and spring cleaning resets it afterwards. Winter cleaning maintains a sealed house while heating runs and windows stay shut. Its jobs — radiators, filters, condensation, airing, grit — answer winter physics, so the task lists barely overlap.
How often should I air rooms when it is freezing outside?
Once a day for about 10 minutes with windows wide open is enough for most homes, plus after showers and laundry drying. Short, wide airing swaps stale air fast without chilling walls and furniture. Longer, tilted-window airing wastes heat and cools surfaces, which makes condensation worse.
What humidity should a home sit at in winter?
Aim for roughly 40–55% relative humidity. Below that, air feels harsh and wood and skin dry out. Above it, moisture condenses on cold windows and walls and mould risk rises fast. A cheap hygrometer in the living room and main bedroom makes the number visible.
Why do my radiators smell dusty when the heating first runs?
Dust settles on and behind radiators all summer, and the first heat bakes it and lifts it into the room air. Brushing, vacuuming behind, and washing the panels at the start of the season removes most of it. If the smell returns mid-winter, repeat the brush and vacuum pass.
