morzh;

ipwizard had a good video of using his ultrasonic cleaner. Unfortunately when I tried to use my son's unit, it shorted out. It was the same brand and model as ipwizard's unit. It turned out that when my son used his with a vinegar solution, some of it splashed to the top of the metal bin or sink in the unit and ran up over the edge and fell down on the circuit boards. It corroded the board to the point that some of the parts were floating around loose.

On this capacitor I used a hot water and detergent solution, plus on the external parts I finally resorted to using a pink pearl eraser to remove some stubborn corrosion. It looks pretty good now. Mechanically it moves smoothly after re-lubrication with a small amount of 3-In-1 oil and lithium grease. The oil served to help liquify the lithium grease and get it down into the bearings.

I will re-install the capacitor as soon as I get the chassis repainted. It had significant corrosion on the top due to mice making a nest under the push-button control assembly and directly in front of the tuning capacitor. It was a really nasty mess.
