trumpet oil composition
well i actually happen to have a trumpet whose valve keys are stuck. on youtube i got to learn that in order to free those valves, i need to purchase a special oil meant for trumpets and other brass instruments.
what i want to know is , will it be safe if i used some ordinary lubrication oil, such as the ones used for sewing machines ? please advise
