I know the problems restorers face. You have a nice piece of equipment, be it jukebox, arcade, or video, but it is covered in rust. What do you do? Sand it off? Sand blast it? Those only dig into the metal and destroy it plus they take away the aged charm of the piece.
There is a better way to remove rust from arcade parts.
I purchased a Shoot The Bear dog mechanism on eBay and it was very rusty. I wanted it for a restored game so to go in one of my games it had to be perfect.
Now the question is how do you easily remove rust from a complicated part without removing metal. It turns out there is a simple electro chemical process that will do the trick.
All you need is a plastic container, a 2 amp battery charger, and a box of Arm and Hammer Super Washing Soda with Sodium Carbonate.
Take a tank of water,
put 1 tea spoon of washing powder for every pint of water in your tank, put in the part, connect Negative lead of the battery charger to part, and the Positive lead to a steel rod in the tank. You can use any steel scrap, even steel conduit.
This wWill bubble out hydrogen so you need ventalation. In 48 hours it will completely get rid of rust on large parts, less time for smaller parts.
