As cleaning professionals, we know how much you care for your vehicle. That is why we use only hog brushes in our facility and nothing else for our prep station. Hog hair brushes are widely used, because they are soft, durable, and naturally porous, making them effective at cleaning without scratching paint. The porous nature of hog hair allows the brush to hold more soap and foam, providing a better lather and a more thorough clean.  Further down is a more detail explanation about the equipment.
