The Vevor car wash brush is designed to make cleaning cars, RVs, boats, trucks, and other surfaces easier with an extendable handle that reaches up to 66.7 inches. Its 12-inch brush head uses soft PVC bristles to remove dirt and stains while helping protect painted surfaces from scratches. The flow-thru design connects to a garden hose for simultaneous rinsing and scrubbing, with an on/off switch for water control. A lightweight aluminum alloy handle assembles into multiple lengths for flexible cleaning in high or hard-to-reach areas.
