Hi once again trumpet masters, I have a pressing question; can I clean my trumpet thoroughly by fully submerging it in water? I've been playing the trumpet for only a year, and never heard of anything like this till my band teacher brought this up recently, and I thought it sounded pretty ludicrous, cause wouldn't it mess up the pressure within the valve chambers or anything? If suppose it is indeed an 'orthodox' method to clean the trumpet...how should I go about doing it? Are there any specific things to follow I.e temperature of the water, how long to submerge it, and how do I dry it (especially the insides)? Because I've never cleaned my trumpet in anyway at all, except by polishing it, oiling valves etc. And I suspect that it's bound to be dirty on the inside. Any advice is appreciated, thanks!
