De-misting advice

Hi Guys

How do you peeps de-mist you windows on the move? We have a 1999 Mk2 which mists up really badly on the side windows passenger and drivers side.

Even if the blowers are set to the window postion the do not de-mist. Tried it with the aircon on and nothing. Just the little quarter panel window seems to clear a little.

Got the heater set to vent from outside not recirculate. Its becoming a bit of a pain. Carpet is dry and the roof doesnt leak.

Anybody got any tips?

Thanks

Once the windscreen is clear, I tend to get best results in my mark1 by directing the air to feet and face and pointing the side vents directly at the windows. Seems to keep it clear even with the air con off.

For best results I just drop the roof [:D]

 My Mk1 is used almost daily and I don’t suffer condensation/misting problems other than reasonably expect in any other car.
Maybe an issue if it’s not a"dailydrive" due to lack of air being circulated on a regular basis? - Take it out more, and maybe drop the windows a little to get the air moving & changing.
Side vents to the side windows, centre vents to rear - after front de-mist as mentioned above - and all ok.

Thanks guys.

It must be the way the eyeball vents are set thats the problem.

I’ll give it a go pointing the vents to the window and see what happens. The car is a daily driver but its mainly my wifes car so I dont get to play that often.

 

 

 Oh - and not set to “Recirculate” either.
A spell with the AC on will help to de-humidify the air, as well as keeping the AC system healthy.

Also check that your roof drains (near seat belt pillars) are not full of water. If they are blocked this keeps water in the car at all times and can mean more misting. If water is in them take an old wire coathanger apart and gently push it down the hole until the water runs out onto the floor beneath the car - then you know it is clear.

 

 

They mist up very easily in wet weather - I find that if you have the direction set to the ‘half windscreen, half floor’ setting and on full heat and level 3 fan and none-recirculate, it de-mists really quickly. Once demisted, turn the temp down to half hot/cold setting and level 1 fan, and same direction and it stays demisted. Oh - and don’t sit in the car in the wet with the engine off or you’ll have it all to do again within 5mins lol. At least you’ve got aircon - I’m dreading a wet humid summer !!

try this, seems to work for my cars…

Tried to qoute but not working again . -------------------------------- Is this Comma stuff ok on a plastic window . I have no problems with fogging or misting up except the usual this time of year on the back plasic window.--------------- Thanks ( no line spacing today either)

 

No! I just checked and it states on the box not to use on transparent plastic windows, sorry!

DOH !!!

Thanks anyway.

Mazda Owners Manual has a large boxed "Warning!’ not to use re-circulate on cold or rainy days, as it will mist the windows and obscure vision - it advises to use air-con on to de-humidify the air being blasted up the windscreen but normal air intake.

i keep one of the old wiper blades at the RHS of driver seat.

start up, quick wipe with blade all round inside, including both screens on a bad morning, then blast with aircon.

I agree with Bluenoes!

You can also get soft squeegees from hardware shops. They’re designed for shower screens and use soft enough rubber to be safe for plastic screens and glass alike.
The 5 is easy to demist because of its tiny cabin - just open the windows fully for about 30 seconds whilst moving - works a treat! Then squeegee or even a 50p demister pad from Halfords if the windows are not totally clear, and you’re away!
As far as I know, these demister products and the near-identical rain repellents are generally risky on plastic screens. But plastic screen polish does a reasonable job of repelling rain from the outside - indeed, any car polish aids in water beading, so its generally always going to be a safe bet.
