Jax Wax Wheel Woolies are the perfect tool for cleaning your vehicle's wheels. The fibers of the woolies perfectly form into smaller cracks, curves, and crevices to remove dust and debris that can be hard to get to with other cleaning aids. Wheel Woolies are extremely safe, featuring a metal-free design which reduces scratches and brush splatter. In addition, the soft, dense carpet fibers of Jax Wax Wheel Woolies are 100 percent polypropylene, recyclable and chemical resistant.
