Everyone knows that boat bottoms can quickly accumulate unwanted growth, especially in a saltwater environment, and everyone should know the importance of keeping them clean. Doing so requires a good bit of elbow grease. It's a chore that's no fun, any way you slice it. So here's an easy and inexpensive trick that makes this task a little bit easier on your upper body. My father, being the clever fellow that he is, suggested putting an old foam fender on the end of a scrub brush. Naturally, the float forces the brush upward, toward the bottom of the boat. This makes it possible to scrub with force using minimal effort. I prefer to use an old fender, but a pool noodle works just as well.
