The club scrub is a great way to keep your clubs clean during a round. I make sure to get as much off the club prior to using the club scrub so it does not fill up with dirt.
This version versus the neoprene version is much more flexible so you have a better feel of the ball or club inside. This is so much better than using a wet towel - a towel will dry out and the club scrub will not. The CS also has better scrubbing ability than a towel as well.
You hang it in a convenient spot so you use it after shots.
