it is perhaps a combo of dust and fumes deposited on there... methyl Ethel
keytone... but then the cleaner will cause your liver to drop out of your
body an and is a really bad cancer thing.....


another thing that might be better is to take it to a clock shop where they
have some wonder solvents and a large ultra sonic cleaner....

let them breathe the various fumes.......

be careful with any of this stuff you use.....
