Deoxit Convergence Pots?

[TinCanAlley]

I'm about to change the capacitors on the remote control board noted in the troubleshooting PDF. If this works, and the set starts turning on and off via remote and/or power button, I want to redo the all the purity, gray scale and convergence over as I was never fully satisfied the last time I did it.

I know the convergence pots don't get much rotating, but after 51 years, would you say it might be advantageous to clean them with deoxit? I know that's a no no on the 3 ferrite core (inductors?), but the other 9 are standard pots.

Also, since I'll be starting from scratch, I'm going to deoxit the setup switch in hopes it fixes the issue of no lines showing when in setup mode.

What about the other controls (Focus, G2s, Horizontal Hold etc.)?

I'm attaching a pic of the convergence board. It looks as though the inductor core for the blue convergence has been damaged. The other 2 have a nice hex socket and the blue looks mangled. Since it has converged the blue lines, I'm assuming it is still working, but might not accept a tool to adjust.
