Harmonicas are easy to take apart and clean, then reassemble again. The SWAN SW 1664 C 16H 64R is a good example. The act of playing harmonica leads to deterioration of reeds, cover plates and the comb. That’s because breath carries contaminants with it that build up on those parts. Proper cleaning at regular intervals can help prevent corrosion and extend the life of your harmonica. Frequent cleaning of the comb will maintain its aesthetic appeal. Use alcohol to clean the reeds and carefully wipe them dry. Always do the same with the cover plates. Make sure to reassemble the instrument when every component has dried. Cleaning your harmonica is all about getting it right the first time and your instruction manual should help.
