What Product to Use to Keep Car Windows from Fogging Up

Top Tip: rubbing an avocado onto the glass doesn’t help with fogging and leaves a big mess

Steamy, fogged up windows are a serious nuisance for all cars, new and old, so finding ways to keep them clear at all times is useful and it also makes driving safer. There are, we’re sure, many myths out there regarding the best way and/or product to keep car glass fog free, but they need to be tested first in order to gauge their usefulness.

These two videos posted courtesy of ChrisFix try to do just that, with surprising if a bit inconclusive results. Basically, out of all products tested (which included an avocado and mouthwash, among others) the most effective was toothpaste, followed by shaving cream.

Nothing else tried in the videos really worked, well, aside from the onion which prevented some fogging, yet its performance could be described as patchy at best.
