I have a what I believe to be a Russian rotary Bb trumpet. I picked it up cheap on eBay. It doesn't seem to need a thorough cleaning, but I don't like playing a used horn (direct from a third party) without at least doing a quick clean in antibacterial dish soap and water. I know you don't want to clean a piston trumpet without removing the pistons (due to the cork/felt/whatever pads on the valve). Is the same true of rotary trumpets (not sure I'm up to removing rotors myself)? Could I simply flush it with soapy water with the valves in place, or do the rotors need to be removed? Or, I guess is there a preferred method for disenfecting a trumpet other than a cleaning?
