Do not use a wire brush to clean rims, because wire brushes are made of very stiff and hard wires.These wires will scratch the surface of the rims and wheels, and the wire brushes are very abrasive. 
Wire brushes are often used on grills to clean the grates, and to remove stains such as oil and grease from floors or other surfaces. Wire brushes are often used in steel or aluminum surface treatment.
We should use a nylon or boar's hair brush to clean wheels and rims, because these brushes are soft and clean the rims without scratching the surface or removing any coatings that have been applied.
