My favorite mouse is acting up.
Buttons double-click on a single-click and sometimes do not click at all.

I tried repeatedly tapping to try to clean but does not last.

Unfortunately this mouse is no longer available anywhere (at least at a
reasonable price).

Love it because of its size and it is USB (no batteries !).

Is it possible to do my own refurbishment ?
Suggestions ?
Links please !

Thanks !
