Condensation on windows - advice on stopping/clearing

[Isthisblocked]

Moved 18 months ago into average 60’s three bed semi in good structural order. But the windows have a lot of condensation on winter mornings. The cold weather last night brought the first wet windows of the season. Last winter I mopped with kitchen towel every morning, but it’s time-consuming and expensive. Advice please on how I may avoid this and then how I may clear it. I am thinking of a dehumidifier - would I need one in every room? Is it easy to clear if I buy a Karcher window Vac? I don’t really want to buy a window vac, partly unexpected expense and partly finding somewhere to store it in a small house. Please help me with advice on dehumidifiers and tell me if you clear with a window Vac.

It is a bit counter intuitive, and I'm assuming that you leave the door shut? Opening the door would work just as well. I can hear the tone of the fan change when I open either door or window. It's unlikely that your bathroom is completely air tight, but modern fans have such a high flow rate that they can't pull sufficient replacement air in through the gaps around the door so having the window open even a little helps a lot.

I put one of those moisture absorbing things on each windowsill and that does the trick. Got mine in Asda yesterday, I think £1.25 each.

Wouldn't leaving the windows slightly open (mine have a slightly ajar setting that they can be locked in) be the same as having trickle vents put in?
