Wrap Hub advising you to avoid pressure washing your wrapped car, as it can cause the wrap to tear or may result in bubbles. As we mentioned before, it is better to use the hand washing method.
Also keep in mind that use a soft cloth or sponge while washing the car. You have to make sure that each and every touch is gentle. And also ensure that all soap or shampoo which you have used cleaning are thoroughly rinsed off to prevent the wrap from damaging.
