How do you clean a harmonica?
Rinse the harmonica with lukewarm water, then tap it against your hand, with the mouthpiece facing down, to remove any residual water. Leave it out to dry thoroughly afterwards.
Does water ruin a harmonica?
If you have eaten or drunk anything right before playing, rinse your mouth with water. Remnants of food can get blown into the harmonica, and sugar or other contaminants from non-water beverages can build up a residue in the harmonica. Refrain from playing right after brushing your teeth.
