Re: Unfreezing rotors
I had a lot of luck earlier this year applying Hetman Rotor Oil to the back exterior of the valve where. 2 drops, sit, wiggle, repeat.
Worked on 4 rotor tubas as well as several of our horns
Well we're taking out concert instruments and many haven't been played all summer (of course).
Got some stuck rotors on concert French horns. What is the best way to unstick these things?
