I must admit, when I first pulled out my accordion after a looooooooon hiatus, it didnt sound too healty. After a short while things started to loosen up and sound noticeably better after I started playing a little more regularly.
The one thing that is not improving is that even after 24 hours of no use, the registers stick slightly. One run through all the registers and all is well again.
I am wondering would a little well placed spray of Elmers Dry Lubricant solve that issue for me? I know better than even look at a bottle of WD40 and the accordion at the same time.
