No problem, Alan. When I read, I thought about changing the alcohol for white vinegar. I’ve been able to disassemble the melodica, really it is like your example above. Apparently the gaskets need to be changed. I still have not started to remove the old ones, but one of my doubts is how to remove the glue that remains on the plastic or I can glue over the “old glue” if you understand what I mean ( I know a specific product for remove glue, but it has an extremely strong smell). Later I’ll try to post some pictures of the disassembled Pianica 32A. I’m sorry about English, I’m trying my best here from Brazil. Thank you very much for the help.
