① Disassembly of Trumpet
Remove the insertion / extraction tube, pistons, and bottom cap.

The pistons are further disassembled. The felt is not washed, so remove it and replace it if it is

Be careful not to leave any detergent on the instrument.

④ Wipe off the water
Use gauze, a cleaning rod, swabs, etc. to remove the water in the tube. It is easy to use a cotton swab on the pistons.

If you are concerned about the discoloration of the instrument, polish it using polish.
So, I’ve introduced how to wash the trumpet. You will feel refreshed if you can wash yours completely. When the inside of the pipe is clean, the feeling of blowing may change. It may be better to avoid cleaning just before an important performance such as a concert or competition. Please try washing your trumpet completely, for which you have plenty of time now.
