You’re looking at a well-made brush with bristles that are nice and long and that are stiff enough to clean dirt and mud but soft enough to use on chrome and alloy with no worries. This brush comes in at a mighty 18 inches, which includes 9.5 inches of brush head. That is a lot of cleaning surface on one product.
On the one hand, it allows you to easily access parts of the wheel construction you though were out of reach. It may be a little too big for smaller wheels or more intricately designed alloys and for more detailed cleaning jobs it could be best to pair it with a smaller product.
