How do I care for my harp

A: Harmonicas can take a reasonable amount of abuse. However it is still a
good idea to be a bit careful with them. So don’t play them with your mouth
full of crumbs or drink, leave them to dry a bit after playing and
transport them in their cases. Sometimes it could be useful to take of the
cover plates and clean the reed plates a bit with alcohol and cotton swabs
