Taking care of trumpet valves is usually a simple and straightforward process that entails applying a special lubricating oil on a regular basis and performing some other minor maintenance. The oil is the most important component, as it ensures that the valves work properly when the horn is played, as well as preventing other horn damage. Cleaning the valves on a regular basis, with professional cleaning at least once a year, can help to extend their life.
The most important aspect of trumpet valve care is to keep them properly oiled. Even if you play the trumpet on a daily basis, it’s not a bad idea to oil the valves before each performance. It’s also possible to skip a day or two now and then for convenience and to avoid having to buy more valve oil. If you wait too long between oil changes, the valves can become sticky and abrasive inside the casing.
In addition to oiling the valves, it may be necessary to clean them with a lint-free cloth every now and then. This is especially important if the valves still tend to stick inside the valve casings after being oiled. It’s possible that this is due to dust, lint, or other debris adhering to the valve’s surface. The valves are best cleaned with a dry cloth, but a damp cloth will not harm them. If you use water to clean the valves, make sure to generously oil them afterwards.
By removing lime and copper carbonate, a more thorough annual cleaning can help keep trumpet valves in top shape. The valves’ performance is reduced as a result of these buildups, which may eventually lead to other issues due to abrasion. This type of cleaning should also be done after a long period of inactivity, such as a year or more, to ensure that everything is in good working order.
The bumpers on the valves may also need to be replaced from time to time. These instrument parts are made of felt or a felt-like material and are located on top of the valves. The finger pad collides with the bumper when the valve is depressed. The valve finger pad could make an annoying noise for the player and possibly the listener if the bumpers aren’t in place.
Trumpet valves can last well over a decade if these simple steps are followed. If the problems aren’t too severe, the valves can sometimes be rebuilt once they’ve become old. This should be done a professional, and the instrument should be taken to a reputable repair shop.
