Getting in / out of car when raining always left the upholstery with water marks, looking unsightly and neccitating me having to clean with some sort of spray on wipe off with a sponge type of cleaner / shampoo, leaving the seats damp and not being able to use the car untill the seats had dried out. Until the wife suggested trying wet wipes (she swears by the Aldi ones, (other makes are available) a gentle rub removes the mark without overly wetting the upholstery, a lot less hassle.
