Just dug up the mouse to replace the broken one temporarily, and found the ball not working in two out of four directions.
When I disassembled the whole thing, each wad of dirt was nearly as big as the black magnetic wheels inside the assembly. Ended up just soaking them in a small vial of alcohol. Works perfectly.
And after all these years and all that dirt, I only just realised that the "click" sounds of the scrollball is actually generated by the buzzer inside the mouse. I feel deceived in a weird way. At least iPod clickwheels were stationary (except the very first one, I guess).
