It's happened to you before; you've gotten your wheel brush stuck on the dust guard, brake caliper or rotor. You pull and heave until the brush finally breaks free, only to leave behind fibers or bristles, ruining the brush and your wheel cleaning efforts.
Don't put yourself in that situation again; the Wheel Woolies caliper spoke brushes are meant to reach behind those tight or complex areas near your wheels or brakes, all without clinging to the parts that threaten to shred your brush.
These caliper spoke brushes are adorned with a plush microfiber chemical-resistant head attached to a high-quality polypropylene handle. There's no metal in these brushes, which means there's virtually no risk of scratching or marring wheels in the cleaning process.
The brush head is angled 45 degrees on both the small and large caliper brushes for optimal cleaning angles and clearance.
