Q: Should I soak my harp?
A: No, no, no! Soaking is very bad for your harps, especially for wooden
bodied harps. It might make them more airtight for awhile, but it damages
them in he long run. Never ever soak a chromatic harmonica! –BB
Never is a strong word; if your harps get wet, they will not die, the issue
is swelling of the wooden comb, which can actually create more problems
than it solves, and corrosion of the metal reed plates, reeds themselves or
cover plates, which is not particularly good — HA
