I like to try and keep the car clean and presentable during the coarse of the weekend. Depending on the weather and what else needs fixing this can be a challenge.

The only thing I've really used is one of those floppy duster thingies. This works, but only if it is a light cover of dust. Often times the dirt is thicker and this just spreads it around, or has no effect.

This issue is particularly tough when you've been out on a wet or partially wet track. Obviously washing the car with water is not an option (at least in my situation). So, what do you guys do to keep the car clean at the track? Is there some sort of cleaner I can apply to a dry car that will clean but not scratch up the paint?

Bonus question: How do you keep the car when it sits in your paddock overnight between race days. Put it back in the enclosed trailer, put it on jack-stands, leave it on the ground???

Thanks
