Difficulty: Moderately Easy
Things You’ll Need:
- Rotor oil
- French horn
- Towel
Step1
Purchase the rotor oil for the French horn. You can purchase rotor oil at your local music store.
Step2
Place a few drops of the rotor oil directly below the rotors. The rotors are located where the keys meet the bar on the French horn. Turn the French horn over and place a few drops to the back of each key. Press the keys a few times to work the oil into the rotors.
Step3
Unscrew the rotor caps and put a drop or two of rotor oil inside of the rotors. Make sure you do this for all 4 caps.
Step4
Drip some oil into the tubing for each rotor. You only need to use 2 drops. Wiggle the keys so the oil spreads out through the tubes.
