What kind of repairs and maintenance does saxophone need     First of all, keep dry after using saxophone: after each blow, there will always be some water left in the pipe. As we all know, the erosion of wood by water is quite serious, and it is no exception to metal. So we should always dry the instrument with soft absorbent cloth after each play, especially in wet and rainy areas. It is very important to keep the instrument dry. This can effectively prolong the service life of musical instruments. Another is to keep clean: saxophone structure is complex, sound holes, sound keys up to dozens, irregular cleaning, it is easy to accumulate dust and dirt in the key shaft, key rod and spring, which will seriously affect the mechanical performance of musical instruments. It brings difficulties to playing. The tube body can be cleaned with a cleaning agent suitable for cleaning metal products. Dust removal can be done with an ordinary softer brush. There is also flexibility: the change of saxophone tone mainly depends on the change of sound key and hole, especially the sound key should have a high degree of flexibility, should regularly drop special key oil to enhance its flexibility and prevent rust death. So saxophone maintenance is important.
