Trying to "reform" capacitors reminds me of the old days in the B&W TV
business. We all carried a black box called a picture tube rejuvenator.
This added a few hours to the life of the tube, but replacement was
inevitable. I know of no magic elixir or procedure to restore a capacitor
back to life for any length of time.
