Window cleaning in winter: is it possible?
Window cleaning in winter is possible: inside always, outside in light frost. We explain when to clean, what cold does to glass and how to look after windows yourself.
Many people think windows can only be cleaned from spring to autumn. In fact, window cleaning in winter is perfectly possible — you just need to take the temperature and weather into account.
The short answer
Inside, windows can always be cleaned.
Outside, we clean when the temperature is above −5 °C.
In colder weather we clean windows only from inside and postpone the outside to a warmer day.
Why clean in winter at all
In winter the days are short and every ray of light counts. Dusty or salty glass can absorb a noticeable share of the little daylight there is. The low winter sun shines into the window at an angle and shows every streak and mark you did not notice in summer.
Winter cleaning also suits the time before the holidays: clean windows with fairy lights make a home feel festive at once.
What the cold does
If water gets on the outer glass in frost, it can freeze before it dries and leave a thin layer of ice. That is why the outside is cleaned only in light frost, with little water, and the glass is dried straight away with a squeegee. In hard frost it is not worth cleaning the outer surface.
Never pour hot water on cold glass. A sudden change in temperature can crack the glass — especially if it already has a small scratch or chip.
Condensation and moisture
In winter, condensation often forms on the inside of windows. A little moisture in the morning is normal, but if water runs onto the sill or dark spots appear on the frames, take note:
air the room briefly and effectively several times a day;
do not cover the radiator with thick curtains — warm air needs to reach the glass;
wipe condensation off the sill and frame;
check that the seals are intact and the drainage holes are open.

How to clean windows yourself in winter
Clean during the day, when it is warmest outside.
Use lukewarm water and as little water as possible.
Dry the glass straight away with a squeegee and wipe the frame edges dry.
Do not leave the window open for long — the frames and seals cool down and the room gets cold.
Do not clean the outer glass when it is below −5 °C outside.
When to book
Winter cleaning makes sense if the windows have been dusty since autumn, if you are expecting guests or want a brighter home before the holidays. We clean higher windows from the ground with telescopic poles in winter too, when the weather allows.
