We've been using our manufacturer's sample of this brush for a few years around the Service Course and at the races, but didn't offer it for sale until now. We love it, but could never quite define its purpose well enough.
Finally, we decided people might just like it for the same diverse list of things we do, namely scrubbing mud, grit, and grease from:
Sidewalls and Treads
Our Scrub Brush is made with the same water-holding, dirt- and grease-shedding tampico fiber bristles as our Wash Kit brushes, set in a wood block handle. The bristles are shorter than those in our Wash Kit brushes, which adds stiffness for additional scrubbing power. The ends are pointed, to work into corners a bit better.
The Scrub Brush measures 9 inches long, 2.5 inches wide, and features a tapered center to fit the hand, a grooved edge for grip, and a hang cord. It's nice.
