[HAM] WD-40 - Vibrato scanner - M-102 ??

[David Damroze]

  What you say makes sense to me regarding the porousness of the bronze. 
It sounds like I need to take the scanner apart to clean it. I
was hoping I could spray something in there to loosen it up and then 
re-oil it.
   Could I just remove the screw at the bottom to allow the gunk to run 
out without having
to actually dismantle the vibrato ?
   What are some products with denatured alcohol that are appropriate to 
this application ?
     I have dribbled a little Hammond oil in there and am giving the 
bracket a push with a screwdriver
once in a while to try to loosen it. It does move with enough pressure. 
Maybe after it sits over night.
