Need IBM Model -M Tech Support

[chalcedony]

I have a stack of these things, that are broken in various ways. Last night I got milk in the one I'm using. Today it's typing double characters.

I haven't had great luck with disassembling them to dry them out, or having them work any better after I've cleaned them.

Suggestions please?
