After using the vinegar, febreeze, ozium, or whatever flavor of deoderizer you choose. I highly recommend using a small bucket of damp rid that you can pick up from your local hardware store. This stuff is made to absorb moisture out of basements and works amazing. You will be really surprised at how much moisture this stuff will pull out of your vehicle in just one night. I have been using it as part of my deoderizing process for a couple of years and now swear by the stuff.
