Caig Labs Contact Cleaner / PTO Lubricant

The DeOxit spray is the closest thing to magic on switches and pots. Use 
it on all Drake rotary switches and pots. Cleans up intermittent contact 
on bandwidth and filter switches, and eliminates noise on AF and RF gain 
pots. Of course this works on any brand of electronic equipment.

The copper-doped grease is the best lubricant for the PTO lead screw. 
Not only lubricates, but provides a better ground on the PTO slug assembly.

     * Can of DeOxit or a small jar of copper grease: $15.00 US

I've got the warbly LMO again on one of my SB-303's.  I had been fixing 
this by dragging clean cardstock through the capacitor's finger until it 
comes out clean and spritzing a little CAIG on it.

Now I wonder if copper grease wouldn't be better.

Has anyone tried this?
