Hi folks. With this hot and humid weather, I am wondering if anyone has had experience with keeping accordions from getting ruined from the climate. I have a front room that is air conditioned sometimes, not all the time. I usually keep my accordions covered with a cloth cover, but I can also store them in the case or in a soft back pack case. My concern is if they are in a hard case, would that keep moisture in or out? Also are there dehumidifiers for accordions that can be placed inside of a case? Any ideas, suggestions? Thanks-
