I think some of these other guyz covered this allready but, i'd stay away from "cover" scents. You can't hide one scent by dumping some scent of annother type on top of it.

I think I'd use any of the carbon spray's, soaps, and shampoos. They are used to eliminate scents.

It would help to reduce some of your equipment, like leaving your girlfriend at the truck. J/k.

But seriously, stay away from the masking scents... they only add more "forign" scents to your allready forign scent!
