Ugh, can’t edit.
Either way though, whether you’re right or me – it needs to go into the garage, because that’s too much water to rectify now. Even driving with heating now, all you do is “hide” the moisture until the car cools down again – and the humidity at the moment is too high to try and dry it with an external heat source. I’ve done so before, but that was in autumn and it was possible to ventilate the car while heating the interior – now you’d just pull even more moisture in.
What i can suggest, though this level of ingress (regardless of where it’s coming from) is way beyond what those can do, on Amazon there’s char coal packages. These here.
We’ve got a dozen or so dotted around our car, even in the current climate our windows don’t fog (i don’t turn on the heating when dropping my wife off, roughly a 2 mile drive) at all. They actually do work within reason – once the van is dry, just through a few pounds of those in (dotted around in the car – we’ve got one on the dashboard, a few in the door cards, few in the boot and under the seats), at the very least it’ll alleviate the issue.
edit: not sure what’s with these weird previews from amazon links – just go to amazon and search for “CLEVAST Bamboo Charcoal Air Purifying Bags”.
