If you follow the directions of use you will not scratch your car, guaranteed. Evershine is formulated to emulsify or totally surround the dirt and dust particles, slightly lifting them off the surface of your paintwork, prior to wiping over. Clean your car,one panel at a time. Do not scrub at hard to remove items such as bird droppings. Spray Evershine onto the effected area and let it soak into and soften the itembefore you wipe over. Repeat this step if necessary to totally remove without a scratch.
