Oiling the Valves[edit]


  1. Trumpet with sticky valves
  2. Valve Oil
  3. Oil Rag

Procedure for each valve to be oiled:

  1. Unscrew the top valve cap.
  2. Gently remove the valve from the casing. This is a very sensitive part of the instrument, any scraping or denting will impair the valve's function!
  3. Using the oil rag, wipe down the valve to remove any accumulated dirt/gunk and the old oil.
  4. Apply plenty of valve oil to the clean valve, careful not to drip extra oil on your nice clothes or good carpet.
  5. Gently replace the valve into the valve casing.
  6. Rotate the valve in the casing to make sure oil is spread evenly across the piston's surface.
  7. Align the valve guides with the casing (usually this means with the stamped number facing the mouthpiece). Typically they "click" when they're in the right spot.
  8. Thread and tighten the top valve cap.
  9. Repeat on the other two valves.
