Winter: mud, salt and radiators

A home does not get dirtier in winter by accident. Three specific things change in November and they compound: everything outside is wet, the paths are salted, and the windows stop being opened. Each one is manageable on its own. Together they are why floors look tired by February, why walls above radiators go grey, and why a flat that was fine in September smells faintly of itself by Christmas. None of it needs more cleaning — it needs different cleaning, in about four places.

Winter brings three problems, not one

People talk about winter mess as though it were simply more dirt. It is not: it is three different problems that happen to arrive in the same month.

• Water and grit, carried in on shoes from wet streets, which grinds into floors.
• De-icing salt, which behaves nothing like dirt and damages what it sits on.
• Closed windows and wet fabric, which changes the air in a flat and starts condensation.

Each has a different answer, and the reason winter feels overwhelming is that people apply the same answer — more mopping — to all three, which only properly addresses the first.

Salt is the expensive one

If you take one thing from this article, take this. De-icing salt tracked in from the street is the single most damaging thing that enters a Dutch home all year, and almost nobody treats it with any urgency.

Salt is abrasive — it is crystalline, and walking on it drags hard crystals across a floor surface. It is also hygroscopic: it draws moisture, so it stays damp and keeps working. On a wooden or laminate floor it dulls the finish and can leave white marks; on natural stone it can etch; on carpet it leaves stiff, pale patches; and it corrodes metal, which is why the bottom of a radiator or a door frame in a hallway starts to look bad.

The white tidemark on a hall floor in January is not a stain. It is a small pile of crystals, still working.

What to do: remove it the same day, and do it wet. Vacuum first to lift the loose crystals, then mop with plenty of clean warm water — this is the one job where you want more water and less product, because you are dissolving and lifting rather than degreasing. Change the water; salty water re-deposits salt. On hard floors, a splash of white vinegar in the rinse helps with the white haze, except on natural stone, where acid is the wrong answer entirely.

The entrance does most of the work

Everything above arrives through one door, which means one square metre of hallway decides how much of the winter reaches the rest of the house.

The arrangement that works is two mats, and it is not fussy — it is what every shop and office in the country does, for exactly this reason:

• Outside: a coarse scraper mat to knock grit and salt off the sole before the door opens.
• Inside: a long absorbent mat — longer than people think, ideally enough for several steps — to take the water that is still there.

Add a boot tray with a lip for wet shoes, so the water stays in one place instead of running along a skirting board, and a hook for wet coats that is not over a wooden floor. That is the whole system, and it removes more winter dirt than an extra mop session every week.

Lift and clean under the mats regularly. A mat that is never lifted stops being a mat and becomes a lid — and in winter it is a lid over damp salty grit, which is the worst possible thing to leave sitting on a floor.

Radiators and the grey wall above them

Turn the heating on and a radiator starts a convection current: cool air is drawn in at the bottom, warmed, and rises up the wall carrying dust with it. Where that air slows and cools, it drops what it is carrying — which is why the wall above a radiator greys over a single season, and why the tops of nearby picture frames and curtain rails collect fastest.

Three jobs, once at the start of the season and once mid-winter:

• Inside and behind the radiator. The fins hold an astonishing amount of dust, which then bakes and smells faintly for the first week of heating. A long thin brush or a vacuum crevice tool with the radiator cold.
• The floor underneath, which nobody reaches during the rest of the year.
• The wall above, gently, with a damp cloth — and expect it to be greyer than you thought.

Doing this before the heating goes on properly is the difference between a room that smells of warm dust for a week in November and one that does not.

Wet coats, closed windows and the smell of winter

The third problem is air. In winter the windows stay shut, and at the same time the house is asked to dry several coats, shoes, an umbrella and often the laundry. All of that water goes into the air, and the air has nowhere to go.

The result is the familiar winter combination: windows that stream with condensation in the morning, a flat that smells faintly musty, and eventually black speckles in the corner of a window reveal — which is where this becomes a real problem rather than an unpleasant one. That distinction is the whole subject of condensation or a leak.

The counter-intuitive answer is to ventilate more in winter, not less — briefly and properly. Ten minutes with windows at both ends of the home, twice a day, changes the air without cooling the walls, and it costs far less heat than people fear. Drying laundry outside or in a vented dryer whenever possible is the other half.

The November list

One evening, once a year, and winter behaves completely differently:

1. Put the two mats down, and buy the inside one longer than feels necessary.
2. Clean inside, behind and under every radiator before the heating runs properly.
3. Wipe the walls above the radiators while they are still only slightly grey.
4. Set up a boot tray and a coat hook that are not over a floor you care about.
5. Check the seals on windows and the balcony door — draughts and leaks both show up now.
6. Agree a ventilation routine with whoever else lives there, so it is not one person opening windows and another closing them.

And in the middle of it all, the honest note: winter is the season when households most often decide they have run out of hours, because the same house now needs more attention at the time of year with the least daylight and the most going on. If that is where you are, it is the normal moment to hand the recurring half over — a regular visit through the dark months and back to doing it yourself in spring is a perfectly sensible arrangement, and more common than people assume.
