foggy windscreens

I got onto " RainX" about 2 years ago and reckon it is one of the best products that I have used, They do an exterior and interior version and both are amazing. The exterior version actually gets better each time you put it on (I guessit leaves residual each time which builds up). Not cheap, but a little goes a long way, and it works.

aircon works fine for me...no need to spend extra on stuff that may or may not work

"P.S.The no-name brand hair spray has made the vehicle smell like a pox doctors clerks boudoir! "

ROFLMAO

Guys, just get a bar of soap (dry) and put a few streaks over the glass rub in so as to remove the streaks. Works a brilliantly. Used this method in our bathroom and ensuite for years on the mirrors, stops them steaming up a treat. Also it wont pong up your vehicle or gas you while your applying it.

I can't believe some of you blokes.You spend a fortune on all sorts of stuff and baulk at spending a few dollars on the best safety product available for glass. Just bite the bullet and get some "Rainex"(both interior and exterior)and you won't regret it.

From what adventure are you aware of that scent?

hahahaha

oh and I use Rain-X on the outside and aircon on the inside

for windows treatments i've been using rainex (external)since 1978. nothing matches it's performance for the purpose.

For the foggy glass problems I too have tried the rainex anti-fog, alas that particular product failed to impress me. It actually made the problem worse. I've experimented with many other types. Even tried metho.
Well the only success I came up up with was plain old water. Very Hot - the hottest you can bear in fact.
A bucket of it, and use a wettex (not a brand new one though as it deposits it's own smearing contaminants) use one that has been used in the laundry a couple of days only first.
My method:
sitting in the car, dip, squeeze out and then sweep the hot wettex vertically in one direction only, not up-down-up. This helps reduce any re-smearing onto the now hot wet glass surface. (You can demo the same re-smear effect by wiping spectacle glass to and fro with a kleenex)
Finish the job by now redipping and then really squeezing the wettex and repeat the motions. You'll notice the steam effect on the window, and straight away the difference the sqeaky clean surface is. if it has'nt dried in less than 1 min, the surface isnt sqeaky clean yet, just repeat that area.
You won't get any where as much foggyed effects for weeks now. I don't and live in a cold foggy area of SE victoria.
Other effects that compound fogged glass problems come from the vinyl dash. Again the use of very hot water / wettex does a good job. (don't use the same wettex though on the glass as you have used on the dash)

Any fog that does eventuate now will be extremely reduced, so it's always a good idea to use your demister, with aircon selected to utilise the dried air supply.

Why don't you just run the aircon with some heat added in? Or am I missing something here?

Another vote for RainX here, have used it for a few years and it is brilliant. One application lasts for ages.

Thanks,

Aaron.
