H.W. Brass-Saver® sets have revolutionized the way brass players clean corrosive mineral deposits from the inside of their horns. These amazing brushes can be used wet or dry, they won't get stuck and unlike the traditional snake they contain no metal so they will not scratch. Their unique design is so flexible they reach parts of the horn previously unaccessible. For a consistent sound use the H.W. Brass-Saver® set; the ultimate cleaning system for your brass instrument.
I purchased this quite expensive item thinking it would be amazing for my horn but it doesn't go through all of the slides so it doesn't really clean well. It does not fit through any of the slides for key 1 and 3. I should have just bought the metal one which is 1/3 of the price that will work for sure. Very disappointed.
