Hi all! I'm about to wash out my cornet, this is my plan, please correct my errors and tell me things I should do if I don't already plan to do them, thanks!! 1) Take it apart, tuning slides, and valves! 2) Leave it soak in the bath for 10 mins in cold water, don't put valves in water 3) I got these bristle brushes in a cleaning kit so brush the insides of each tube i can get into 4) Put cold water through it 5) Dry and put back together, grease the slides. 6) Rinse in cold water,dry and oil valves put valves back in. 7) Go over with a silver polish cloth thing! Thanks everyone, I haven't ever really been told how do to clean it out properly, so is this right?
