[R-390] Re: corroded tube pins

[Bill Hawkins]

The mild acid is carbonic acid, from the CO2 added to the
flavored water to make it tickle. Any carbonated beverage
will work.

Does it work on corroded tube pins? Depends on what corroded
them. Pretty sure the pins could fall off without affecting
the vintage vacuum.

Anybody know the base metal and plating of tube pins? It
probably varies with the vintage.

May the sun rise higher in the sky for the next six months,

This offered as a possible 'wives tale' solution and NOT from a
scientific viewpoint. I'm hesitant to offer this, and I hope I'm
not making myself appear foolish by posting.

You might also try bundling them together with a heavy rubber
band and then standing them up in a shallow pan with Coca-Cola
in it. My wife has used this trick on various things over the
years without harming the base object. I have also seen
something on TV about it. As I recall it has to do with a very
mild acid contained in the Coke formula.
