2002 Chrysler 300M Special
I have a special alcohol (I think its isopropyl, but denatured alcohol works as well) based cleaner for the rubber trim and ground effects on my Special. It cleans out wax and grease and restores the color as well. Mothers B2B does this as well, but is really only good for show-day, since it's gone the moment water touches it. In fact, FireM recommended that I use B2B on my rubber trim prior to waxing the car, since it will keep the wax from getting into the textured surface.
