If you go to any store and buy box of baby Wipes and keep it in car and anytime you get chance wipe down the dash and seats (leather or plastic), you will keep them dust free and clean and for a fraction of the cost, not to say you shouldn't use leather conditioner on your leather, this is between conditioning, Don't do the gauges "PLEASE".And before someone trashes this Idea, think of it, these are used on Your babies Butt so not going to have any chemical that is damaging.
