One of my two NeXT mice has had an issue ever since I cleaned off the rollers with IPA. Vertical scrolling only goes up, not down. If I open up the mouse and move the roller directly, it works when the mouse is held upside down but not when right-side up.
I don't have much experience fixing hardware. Does this seem like something worth opening up the mouse to see if I can fix it? Any tips on what specifically to look for in there?

Yeah there's probably just gunk inside you need to clean off.
Thanks! I opened up the mouse and blew out the dust bunnies with compressed air, and it seems to be working fine now. Really glad not to have broken it.
