    Here is the before and after for the rca plugs at the back. Mine were not very corroded and I don't have any corroded ones to try but here you are. Not nearly are dramatic as the wafers. image.jpeg before and

    It seemed to work great for extreme oxidization and not so good for corrosion or left over polish ( a trick from Harold). I was amazed at what it did on the wafers and I am sure it will do the same for selectors.

    Sweet. I'll need to pick up an ultrasonic cleaner sometime soon.

    Here is the speaker selector. I played with the times a little and the concentrations image.jpeg before image.jpeg after. There was no mechanical means to remove the oxidization other then the ultrasonic cleaner. While it was tempting to use something no matter what that would affect the surface, which defeats the whole purpose. I think it turned out great. I was surprised on how oxidized it was and three pitting marks under the contacts.

    Looks real good.

    BTW: One of these sliced to fit between the rails works great to clean switch rails.

    Mind the slider contacts. Some have 2 contact points, the others have 3.
    Make sure they go on the correct plunger.

    Oh I forgot about the "old eraser trick" that would have been great to try. Thanks for the warning on the contacts.
