I didn't expect this to actually work this well. It's incredible. Just slide it across the surface of your car after washing and the water just disappears. It leaves no streaks, swirls, or scratches. I used to use a leaf blower to dry my car but this works so much faster, and no noise. Just wring it out and put it back in the box when done. I usually leave it out to dry for about 20 minutes before putting it up.
