  3. I’m looking for technical help or recommendations on: __NC De-misting the windscreen. The drivers side seems to be take longer to clear than the passenger side.
    Any advice welcome.

Also check the drain channels in the plastic moulding below the windscreen, if blocked it can affect windscreen misting.

If you have aircon, put that on.

Have a feel of the carpet - is the drivers side damp ?
Could be water ingress via the scuttle grommets.

When I rode motorcycles, or when racing, I used to coat the inside of my visor wirh Fairy liquid, and then polish it. I used the same on my NC during the winter months and it helped. Plus as Scarlet Pimpernel suggests, when combined with AC, it worked a treat.

The actual air outlet is biased to the passenger side (have a look down the vent through the windscreen) although the grille is central so the driver’s side can take little bit longer to demist.

Mine isn’t as powerful on the drivers side.

Try switching from recirculate to fresh air. If there’s moisture present in the car such as a minor leak you’ll struggle to demist the screen.

I use a couple of PINGI Dehumidifiers in my wife’s car (my MX5 is garaged), just place them on the top of the dash, one each side. Works very well at stopping misting up overnight.

The dehumidifier packs are the best idea by far. I didn’t know that they even existed until I came on this forum.
Since I’ve started using them, my car interior has been mist free and clear even on frosty nights. I keep one pack on the dash from the windscreen and one pack by the headrests for the rear window.

I’m bemused that I leave the car fog free, go into the supermarket of your choice and when I get back in it fogs up immediately….
