Moisture and small food particles blown into a brass instrument tend to be corrosive to the metal. Failure to remove these accumulations results in tube or "red" rot, frozen slides, slow pistons, and a greatly reduced life of an instrument. The chemical cleaning process includes completely removing corrosive deposits and neutralizing acids, polishing the inside of slide tubes, replacing springs, corks and felts where necessary, correctly aligning valves, lubricating and aligning tuning slides, play testing, disinfecting mouthpiece and cleaning case. Soldering, removing dents, new parts and case repair supplied at an additional charge.
