Mist/fog ?

Anyone know how to stop misting/fogging up inside car?

 

misting/fogging is normally a sign that the car is wet inside somewhere ....

 

Make sure the air con is on and working properly..

 

Is there anything to prevent that from happening. Only hoovered the car today due to the weather being nice.

 

Not using it as a 'Passion Wagon' are you? as I recall in the annals of my distant memories that used to be one of the consequences

 

Wouldn’t do such a thing hahaha!

 

No sense of adventure!

(Either that or you're crocked like me...)

 

@Uncle Benz has advised he’s had quite a few A class with water leaks in the back behind the bumper. Shows up as damp rear foot wells.

If you have that then you’ll get misting up as the car warms up.

As per above use the AC (all the time) as it dries the air.

Also clean the screen (inside) as dust and grease make it worse.

 

Exactly this - aircon left on at all times is the best way to get rid of internal fogging

 

but if the car is wet inside, it'll need more than air con to stop the windows fogging. EmilysMum's car suffered from the drains in the wiper scuttle blocking and the carpet ended up soaking wet ..... it took days to dry out even when the carpet was lifted as best it could be & the weather at the time was fairly hot.

 

Yep , as above , clear the drains below the windscreen by shoving a hose pipe into the holes . Empty any leaves/sludge from the windscreen base and below the bonnet .
Leave aircon on all the time (maybe it's not working correctly from lack of use of needs a recharge ?)
Wait a week and see if that all works .
Obviously if carpets are wet now , that needs dealing with first .
Maybe apply gummipfledge (or silicone grease ) to all the door seals

 

If his profile is correct, this is a 2019 car so there shouldn’t be any problems with damp or rubber seals.

 

According to another thread the OP recently bought it new but not from a dealer? Has it been valeted too enthusiastically and the interior is still damp ?

 

uncle benz is spot on had that 2x 1st time wrecked c/l pump. 2nd time drilled hole in plastic boot insert ,pump in bag comes in top right ,from rear corner and runs over door seal. not yet sorted permanent fix.

 

There was an old trick (actually it was to stop internal freezing) - I used to do this on a van with no heater that I had donkey's years ago: Just wipe a smear of anti-freeze on the inside of the screen. Try a small patch first!

 

Oh yeah , I hadn't spotted the 2019 bit .

 

If you have a dehumidifier put that in the car to dry it out. See how much it gets and once it stops extracting water see if the problem goes away and returns. If it does your car has a leak somewhere and MB need to fix it.

 

Just bought an anti mist spray for the windscreen That should solve the problem. Thanks.

 

Fix the cause, not the symptom ...
Condensation is bad news as it's present on electronics as well as glass.

 

I have an elderly Peugeot 206 and it was misting up terribly. Eventually realised that the rear windows weren't quite wound up tight. Corrected that and bought a bag of silicone (like the stuff they put inside packaging of TVs & phones) and left it on the dash. It completely solved the problem. Available on eBay or Amazon and wonderfully effective. You can pop it in the microwave to dry it out as necessary.
