Please help me identify and estimate the resale value of this accordion

[Jay Hill]

To polish an accordion you could use "Brasso" which will shine up the plastic without visibly scratching it but perhaps better is Meguiars Mirror Glaze used for motorcycle windshields. Frankly I would avoid using alcohol on it. Better is naphtha. Alcohol is for piano keys.
The test of an accordion's conditon is done by sounding each note seperately and listening for a clear normal sounding response.
If anything sounds odd, you would take it to an expert, if you can find one.
Get somebody to play it, and if it works, it's at least good enough to practice with.

Dear Ikesaccordians,

Thank you so much for taking the time to provide me with your cleaning and testing recommendations!
I really appreciate your input!
She deserves some attention before I get her ready to show or go!

Regards,
JH
