Any ideas on how you can prevent the inside of the windscreen freezing overnight in this icy weather?

Thanks Nathan.

A big bag of silica gel to absorb the moisture in the car seems to work ok

Take the car for a decent drive and run the air con, should remove the moisture from the inside of the car. Also take the floor mats out and leave inside to dry if they're damp.

ETA: I think cat litter does the same job as silica gel, absorbing moisture? Might be easier to get hold of.

Buy a landrover, the inside of my windscreen is the least of my worries!

You need to go for a long drive with the air con on,to reduce it, but even then it will keep coming back.

I spent the last few winters with snow and ice inside my jeep for 5 months - kinda get used to it after a bit. Parking in a heated garage temporarily helps, but I think it might actually make it worse in the long run as relative humidity increases with temp. S'pose an air condirioned garage might be best

Leave a couple of hot water bottles with BOILING water in them on top of the dashboard JUST before you go to bed....smile

A couple of tricks I used during the previous few years;
> make sure you bang all excess snow/slush off you boots/shoes before you get in the car
> spray a thin film of deicer on the inside of the screen (it'll last quite a long time)

Obviously they will only work if the inside of the car is completely dry first.

Throw a towel over the windscreen when you park up, in the morning start the car with blowers on and remove towel, screen will be clear and ice free inside and out. Beware, if you don't let it warm up a little you'll get a 100 yards down the road and the screen will suddenly mist / ice up forcing you to pull over...

If you pee in a jug and use some kitchen towel dipped in it to wash the screen it won't fog up or ice.

Guaranteed.

my MR2 t-bar used to get this problem, which is of course caused by a damp car

I used the cat litter in bag idea as a cheap way to absorb moisture - I actually crafted a bag from kitcken towels and masking tape (must have had more time on my hands back then), but a vacumn bag also does the job (tip from honest john website)

The t-bar leakage was cut by spraying silicone spray onto the seals. Assumming your car isn't a t-bar, this stuff from a Halfords yellow spray can should help refresh door, window and sunroof seals for cars that do have proper roofs.

otherwise, I'd try and find the source of the leak if this is a serious problem.

But as other posters have said, snow from your shoes and even your breath is probably enough to cause a haze of ice on the windows each morning

Any more detail on the method for using this silicone spray? Is it simply a matter of giving the seals on all the doors and windows(?) a good dousing with the stuff? I'm fairly sure the Audi's seals are pretty weak, damn thing has a prodigious capability to steam up.

I've got the same problem and it seems to have coincided with my pollen filter starting to smell a bit. Could it be a clogged up and damp pollen filter?

I do this exact thing, I get them from drums of welding wire delivered to work.

Look on IMOC.co.uk - instructions there.

In brief as I remember it: Squidge a decent amount of silicone bath sealant around the contact patches of the roof. Cover in clingfilm, and fit the roof panel. Leave to dry overnight, remove roof, remove clingfilm, win.

I've never got the silica gel / cat litter thing sorted out, but a quick and surprisingly effective way to do it in an MX5 is to run with the heater on full making the car red hot inside, then open the windows while driving along until the air clears and it gets cold. Close windows, repeat. A couple of heat cycles clears a surprising amount of moisture!

Will the air con actually work at the temps we are talking about here though? I was under the impression the compressor wont kick in to stop it damaging itself below certain temps
