Finally, all the gentleness of our Boar's Hair Brush combined with the benefit of constantly flowing water! The great thing about this brush is that the surface remains flushed with water at all times. This is especially important on your first pass on your vehicles surfaces. Here's what I do: rinse the vehicle thoroughly with a steady stream of water to remove any major grit and road grime, spray the surface using Car Wash with our Foaming Sprayer or dip the brush in a bucket of Car Wash suds. Next, turn on the water on the handle, and then working from the top of the vehicle down, lightly brush the wand back and forth removing the grit and road grime as the water flows through the brush. Your car is washed! Makes washing larger SUVs, minivans, trucks or RVs enjoyable! The handle fits standard garden hose threads and is 40" in length. The Boar's Hair Brush is 7" in diameter that fans out to 11" in diameter when you are washing. The rubber bumper edge also eliminates contact damage. Made in the U.S.A.
