I have been asked to sell a King 3B trombone with a F trigger for a friend of mine and I want to clean it out for him as welll. It has a rotary F trigger. Can I soak the whole back section including the trigger in a tub of water and soap with out removing the valve assembly?
If I need to remove the valve can someone (bloke,tubatinker ...etc )) tell me how to take it apart ?
Please help
