I find this helps considerably if left permanently the car until re-generation is required. http://www.ebay.co.uk/itm/SILICA-GEL-COLOUR-CHANGE-FOR-CAMERA-ETC-400-GRAM-BAG-/271078771457?pt=UK_Packaging_Materials&hash=item3f1d8dcb01
I have two, one in use and another on "stand by"

Thanks OAT
How long roughly does it last til it needs regenerating? My car is a large people carrier, not sure if that will effect the 'discharge time'?

All my cars have done this most nights through autumn/winter, it's perfectly normal.

I did read some advice about holiday caravans left over winter that said if you get the cheap cat litter (Lidl/Aldi style) and pour that in a tray and leave it in your caravan it'll help soak up most of the winter moisture..... I guess this'd work for cars too. So, if you don't mind having a washing up bowl full of cat litter sitting in your car.... that's a quick/cheap solution.

Pollen filter was changed 2 years ago, is it worth doing again just in case? Aircon is never on (we live in UK remember )

What causes condensation?

I would change the pollen filter, yes. And put your air conditioning on and leave it on. That will also clear condensation very quickly. Condensation is caused by warmer air coming into contact with the cold glass and depositing water onto the surface.

Air conditioning in cars should be left on permanently. It makes very little difference to your mpg. Mine's never off.

Cheers everyone, I dont park over a puddle or drain, but car is left locked for a week or more sometimes without being used.

Be sure to clear the scuttle of dead wet leaves (thats the plastic at the bottom of the windscreen that the wiper arms come out of) as that can harbour moisture which then gets in.

Also check your air recirculation flat is still working. On some cars (like mine) they fail and can be stuck open or closed. If closed then no fresh air can get in and you'll see condensation frequently. Not all cars have them but the motorised ones can be a pain like mine.

Also if you find it happens more on one side than the other, your windscreen bond may be cracked. I had this once and one side of my windscreen wouldn't clear no matter how hard the blower was, hot or cold, air con or none. Eventually it cracked and I had to get it replaced. When the autoglass bloke took it out he said the entire bond at the bottom had cracked through (potholes no doubt) and that he had virtually no resistance when cutting through it. Not much you can do there except try to put some bathroom sealant in there somehow.

No idea about the pollen filter, mine doesn't even have one so can't comment.

Leaving the air con on does make a difference to mpg, some cars more than others.

On our fiesta 1.25 petrol. It's very noticable, as is the drop in power.

On our C8 2hdi, you'd never know it was on.

That'll be fighting talk around here. I'm always preaching the advantages of A/C, particularly for demisting, plus the fact that if you don't use it at least once a week then it'll stop working but noone listens to me. MInd you I hear of people who refuse to use their car heaters .... .

I find this happens if I have had the dogs in the car when they have been wet. I use the mini dehumidifier things from asda in the car shaved down the side of the passenger seat. They cost £1 and are small containers part filled with crystals that turn to liquid/gel as moisture is absorbed. Each one lasts for months and it solves the problem of wet or frozen windscreens

Car windscreen was wet/damp on the inside this morning, i know it was cold out last night, and had frost on the roof and bonnet til the sun come up onto it, what causes this misting/smearing effect on the inside of the windscreen?

Thanks
