You wash it, until the coating's hydrophobic properties start to wane and that can be years. Washing will be easier than ever: You won't have to wash your vehicle as often as you did before the ceramic coating and you shouldn't need strong detergents. Ceramic coatings work partly because far fewer substances stick to them than to old-school carnauba or polymer waxes, sort of like Teflon on a frying pan. Those substances that do settle are much more easily removed. You can use a wash detergent that's intended for ceramic coatings, or a spray refresher on the paint as you dry. Both can extend the life of the coating itself. Either way, your vehicle will look like you just polished it when you're done. You definitely don't need to wax it once the ceramic is applied. The ceramic coating replaces wax and provides all the gloss and protection you need.
