The dash sock (silica gel to prevent frost forming on windows)

[gone-ot]

...might be an excellent idea down here during the Monsoon Months when temp's are 95-115ºF and humidity is like a "wet sock" slap-in-the-face (pun intended).

Do I see a silica gel group buy coming?

With my LED Fan On indicator, I have noticed that the AC does not run with defrost when it is bitterly cold; like below 20F.

I like the silica defrost sock idea!

Sweet idea! I can imagine using silica gel to prevent the fogging problem in a secondary windshield aeromod.

Check out the kitty litter area at your local grocery or petstore. I've seen a "litter" that's just silica gel crystals. I've used that before for making motorcycle coolant vests (soak in water so the gel picks up moisture but doesn't "drip", which provides evaporative cooling - sort of a like a swamp cooler).

Every pill bottle has silica gel in a little paper packet to keep the pills dry, you can also get silica gel for drying flowers or as was stated, as crystal cat litter.
I was just using some that changes color, blue is dry, pink is wet, it works really well for drying stuff out like cell phones or if you are me, my lap top that I dropped in to standing water... a few hours in a bag of silica gel and it's dry and working just fine!

Personally, I just leave my window cracked open over night, the moist air wants to condense on what is coldest, if the window is open then the coldest thing is the outside as the windshield is still warm, but the windshield is quick to cool so it frosts up quickly.

You can also dry silica gel in the microwave, I don't have one so I used the one next door and found that putting it in for a minute, take it out and stir and cool then put it in for another minute, a flat glass bowl worked best.

what a brilliant idea!!!

as my car doesnt have a/c or a fan!!! i use "fog clear" pretty much isopropyl alcahol or something, it works alright but this is going to have to be product tested

crystal cat litter

Do you know any good brands?

[Niner]

The cat litter crystals I got was just store-brand - just make sure you get the stuff that's *only* crystals (which are a translucent white) and not crystals in clay, because the clay will break down as it goes through wet/dry cycles.

You can also pay for silica gel from gun shops or places online like MidwayUSA. It is used in safes to prevent rust. I pull it from shoe boxes & vitamin/pill bottles also. This way takes a long time to get much gel, unless your wife likes shoes as much as mine does.

Remington makes a "mini-dehumidifier" that plugs into an outlet to get the water out of the silica gel.

There are also some clay products that absorb water out of the air. I believe they are also rechargable. I will have to check on a brand when I get home.
