So the other day I had to clean my trumpet, and I mean REALLY clean it. Normally before I put away my instrument, I just have to empty the spit valve. This is really easy, because all I have to do is press that little button on the valve, and blow through the mouthpiece (the woodwinds in my family are kinda resentful about this since they have to clean their instruments piece by piece each time they put theirs away). Still every month or so I have to take the whole thing apart, run water through it, and scrub out the inside with these trumpet cleaning tools.
Then you lay it out on a towel to dry.
Now if you ever need to clean trumpet, you can!
