I've tried just about everything, you'd think somebody would make an easy way to clean an Aluminum boat. Mother's works great but you'd better be in good shape, lots of elbow grease. Just recently I found what seems to be the best method so far. At Boater World they have a product called Marykate Aluminex. If you use this product first and than use the Mother's it takes a ton of work out of the project. Try it out and hopefully it will work as well for you as it did for me! Just using the Aluminex won't quite cut it, seems to leave a dull finish all by it self.
