So im in college and my 87 wrangler sits outside at home (cause my parents won't drive it) and it doesn't get touched except when I come home, which is about once a month. It has a car cover but moisture and water somehow find their way inside and it gets really muggy/moldyish inside. I was wondering is there something I can put inside the car that will absorb alot of the moisture? I know I have heard of something like that for when you leave your sunroof open and it rains.

 

Yes, its called Damp Rid. I highly recommend it for vehicles stored in musty garages or in storage.

Heres the website for additional items. Its usually available at local hardware stores, and/or Osh.

 

You just need something that will soak up moisture, like those packets of silica-gel that come in the box with a new pair of shoes. I'm sure DampRid is just a jar full of those little dessicant beads that can soak up many times their weight in water vapor.
