Rotary encoder cleaning- SR4021

So I bought a used SR4021 and the rotary encoder for the multi jog wasn't working. I would have replaced it, but Marantz doesn't make the part anymore (90M-SR000340R). I took it apart and cleaned it (there was some dirt in there), but I'm wondering if there are any additional steps that I can take to bring it back to life. I don't know much about this stuff and appreciate your input. Pictures of the rotary encoder are included.
