I've a chronically sticky valve. It was fine when I played regularly ... in the 1970s. The horn went unused for a very long time. What I've done is cleaned it and washed it with oil and taken care not to mix brands. It's good for a while but after an hour or so it sticks again. What would be the next level of cleaning? |

Does it stick mostly on long notes? Every time or just once in a while after the sticking returns?
One thing to try is a thicker or thinner oil. Berpbio oil helped my sticky valves on an old strad. Yamaha and hetmans also produce a thicker vintage oil. |

I have often been very frustrated getting old horns and having sticky valves. After much irritation and many cleanings and valve oil switches I discovered that in a lot of horns that have sat for years there has developed kind of a ring inside the valve casing right where the valve ends in the up position. If you take the valve out and dry out the casing you can usually see with a flashlight or feel it with your pinky finger. I assume this is just oxidation from being exposed for many years. Anyhow takes some extra effort to get off but for me has cured the problem in several tough cases. _________________ Scodwell Boston

If a horn has been sitting for a long time, there is likely dried crud, oxidation, and God only knows what else in the valves.
A competent tech can hone those valves right up for you in a jiffy, probably while you wait if you call ahead. _________________ Yamaha 8310Z trumpet
