Interior condensation

[Tapitha]

Why do the windows of my Minor steam up whenever the weather is damp? This morning I was parked on a supermarket car park and when I came back to the car all the windows were steamed up inside. None of the more modern cars had this problem. My MGB has the same problem. At night it is very dangerous driving along constantly trying to wipe the windscreen.

Damp and cold inside

At the risk of severe frostbite to the fingers try opening the quarterlights

Possible that the carpets are damp and holding moisture in the car, try lifting carpets and under felt out and just using rubber mats and seeing if this helps a bit. Also as Mike says some air flow in the car helps greatly, I keep the drivers window down about 1/2' and it does help dry out things a bit as you motor.

Thats why folks in old cars are well wrapped up and all minors have tartan blankets

Or a crocheted one

Try stuffing an old sock with (clean!)cat litter, tie a knot in it and leave it in the car. It will absorb water from the air and reduce condensation. It will need changing or drying out periodically.

Where do you expect the cat to poo, the other sock?

Perhaps better to use condensation absorbing crystals - available from Ebay/Amazon etc.

It will be - as others point out - dampness inside the car. And very poor 'through flow' ventilation which hadn't been invented when were made. It was always an problem back in the day - hence the sale of 'antimist' cloths from Halfords etc. But as suggested - lift the carpets and underfelt - if it's damp it will be causing rust... Have a look under the rear seat too.......It may be holding a swimming pool.

Simply put, condensate forms when a moist body of air meets a colder surface.
So, all of what folks told you above is correct.

3 ways to eliminate condensate, remove the water source (probably wet carpets) increase ventilation (open windows) or heat your windows.

You are not going to heat the windows and don't want your windows open so this leaves elimination of the source which basically means take the carpets out, something is wet.

I still rate the cat litter trick. It's cheap,works and smells ok...better than a mouldy car. Good luck if you want to get the cat to poo in the other sock, I've always found them impossible to train so would recommend a dog!

I have a couple of these that I keep in the car, OK I don't use her in the winter but keep these in the car while in the garage and they certainly work well.

There is no damp under the carpets, or anywhere else and it lives in a totally dry garage under the house, but we still suffer from condensation when using it in damp weather.

Usually having the heater on full 'Screen' keeps the front screen clear, but as the screen is coming out anyway ahead of the respray, and it needs replacing, because it has a stone chip and it is spreading slightly, I am wondering whether to fit a heated front screen?

What is the experience of these? I assume they are not tinted as well??
