Household cleaners and tips aren't just for the home! I recently took a load of garbage to the local solid waste dump and the smell that was left in my car was horrible. It really doesn't help that it is currently hot outside, which makes all car odors worse! To remove these types of odors, grind Borax into your car's carpet and fabric. Let sit for about an hour and vacuum. The smells will leave with the Borax.
