noo...dont clean the body...
without cleaning the body, the guitar looks more "experienced".
i mean, it will be like its signature...
a vintage guitar should have a vintage look...
hahaha...
probably changing the machine head and refretting the guitar will do...
not sure whether the machanicals inside still run or not is a problem though...
if it runs...you have a nice guitar... (depending on the sound quality though... )
