 You think a washing machine is bad. A jetted bathtub is disgusting. They're disgusting is what they are. When you clean them, they're disgusting. A guy was just talking with a lady about a week ago, and over two dozen times she's run awesome through her system, and she's still getting gunk out. This is actually a very common thing. We sit in our jetted bathtubs. We love them. They're great.
