Default Re: cleaning tuning capacitors

I'm with the dishwasher folk!

I dismantle the cap first, though, and remove the steel balls. Advisable to count the threads on the screw so the spacing (and therefore capacitance) are the same, but prepare for realignment afterwards.

Use thick (water-pump) grease on the bearings.

The advantage of using the dishwasher as opposed to just washing it in a bowl is that the high-pressure spray generated that really does clean everything.
