Has anyone tried this trick for window fogging

[Rayd888]

I wish there was a "Tips and Tricks" forum thread...

I came across this one and wonder if anyone has tried this already. 

Window moisture is a big problem for van dwellers so when I saw this, I wanted to share it here. It looks like it should work, and it's cheap.

I agree, I'd like to see a "Tips and Tricks" section.

Also a "For Sale, Barter, Free, or Wanted" section for build materials and camping/outdoor equipment.

I'd be interested to see if the sock trick works. I was sleeping in my truck cab a couple weeks ago in a spot in Western North Carolina, on a cliff above a river in a forest that was so humid, the OUTSIDE of my windows were fogged! First time for everything, I guess.

Great Idea except once the media is saturated with moisture you may have to change it out. Another option, which is used in aviation is desiccant. Which is basically the same thing. The silica crystals look the same, except incorporated with color. When the color changes from blue to purple the crystals will no longer draw moisture. Then you take the crystals and bake them in the oven at a set temperature to recharge them. Where I live (PNW) I place Desiccant cans in my vehicles that are stored for the winter. Otherwise, the plastic gets covered with fuzzy mildew. Instead of a sock I would use a about a quart size can with lid. perforate the lid with drilled holes. Once the media has absorbed it's limit simply toss in oven and bake until color is restored. Rinse and repeat. You can buy pre-made desiccant containers on line, with the color indicated media.

On the video the guy says it takes 3 days to absorb that amount of moisture?

Scuba divers keep their dive masks from fogging by spitting on the lenses, rubbing it around and briefly rinsing.

I imagine the general humidity of the air and the difference between internal and external temperatures affects how well and how long this works.

I keep the bathroom mirror from fogging by cleaning it with shaving cream. But ventilation fan works so so so much better. So What is silicon kitty liter?

Alas, in general, all of the stuff you see on the Internet about absorbing moisture with cat litter, damprid, salt, or whatever, doesn't work.

Some math ... Typically, a fullsize four-pound bucket of Damprid will absorb less than an ounce of water per day. (A packet or two absorbs only a negligable amount of water.) A typical human exhales about one pint (16 ounces) of water each night. So you would need at least 16 four-pound buckets (74 pounds) just to absorb the moisture you breathe out into the van while you sleep. This assumes you do nothing inside the van (such as cooking or washing up) that adds more moisture to the air.

I once tested it out by putting several damprid packets right on my dash overnight. It made no noticeable difference whatever, and the windows were still fogged less than two inches from the stuff.

How about sleep on your side and pull the covers up over your nose.

Anyone tried these dehumidifiers?

In my apartment, during the summer, I put Ice Melt (for melting ice on sidewalks) in a bucket with a hole on the bottom that's covered with a screen. The Ice Melt draws moisture from the air and it drips through the hole, into another bucket that I put the first bucket into. It works great.

A product that works really well is Rain-X and their Anti-Fog.  I used them when I owned my last vehicle 18 years ago.  Rain X worked so well that I didn't even need to turn on my windshield wipers when it was raining.  (As long as you apply it according to the directions and don't take shortcuts.)  And, in the winter here in Minnesota, the inside of your windows fog up fast and easy.  Anti-Fog worked great.

I've also never found a anti-fog mirror for the shower that really didn't fog up.  (I shave in the shower.)  Rain-X works great on that, too.  Didn't even have to use Anti-Fog.
