it blows the air through fine but not really that good just takes an age to do anything but once it warms up its fine first 2 miles of journey is done at 30mph

These do the job even faster and far more cheaply. Never any chance of making the battery flat either and they don't increase the engine warm up time (cold engine= lots of wear and high fuel consumption). I personally would also be a little concerned about the effects of force cooling only one of a pair of cylinders, but that's just my uninformed opinion.

cheers rob bought one of those static clothes today, im quite impressed with it, i shall see how that fares when it comes to steamed up windows...

My '74 2cv has only drivers side demister... and the tube on the bulkhead has shrunk, meaning I get just a faint draft of warm air onto the screen in front of me. I find an e-cloth to be good for this, small enough to screw up and stick onto the dash but also cleans the screen pretty well.

thanks meshking. i saw this stuff in tesco yesterday which claims if you put it on you wont steam up, going to try it on one of the quarter lights to see if it works before i plaster it on the windshield and it block my vision

I used to use rain-x anti-fog, but it always seemed to make the screen 'fuzzy' when it was stopping the mist. That was, admittedly, 17 years ago so perhaps the formulation has changed....

I bought two anti mist cloths from Halfords the other day, used it once in my car. Threw it away. Gave one to the missus - she used it once, and threw it away.

microfibre glass cleaner cloth for me from now on

Rain-X was and still is bloody awful stuff. It's fine for the outside of an aeroplane canopy and that's what it was designed for, but on a car windscreen at night with the wipers on it's a bloody nightmare. Any moisture left behind by the wipers immediately forms tiny beads which act as thousands of miniature lenses. Not good when you have oncoming headlamps to deal with.

In aeronautical applications it's been superseded by modern replacements which sheet the water away completely rather than breaking it up into tiny droplets. It's just like if you let someone else wash your car and they "helpfully" wax the windscreen

I use a chamois sponge or a microfibre cloth, but they both do the same job in much the same way, once the engine has warmed up I never have problems with front screen misting, but the rear screen is a different matter so I fitted a heated rear screen when I last replaced the roof.

The only chemicals which I put on on my glass are those used purely for cleaning.

I normally do exactly that! Horses for courses, but I much prefer the way the wipers clear the windscreen once it's been done.

My dad's replaced the driver's windscreen on his Land Rover with a heated one. The elements are all but invisible, like the ones used in many modern cars. Both the Land Rover and a 2CV/Dyane use flat screens, so I imagine whoever makes them could make one for our cars as well, for a price.

Personally I just use the rubber squeegee type thing on the back of my ice scraper, as it doesn't turn into a soggy mouldy mess when left on the dash shelf. I've been using bags full of silica gel in the cars this winter, though, and it doesn't seem to be such an issue.

Erm did you ever spend that £10 on a new heater tube James?

Also doesn't someone use old PC fans, as they are the right size and 12V...?
