I have never heard of old breakers being dangerous or lubricating them, and

Maybe he was describing removing the breakers and applying a little
Thomas & Betts Kopper Shield or a silver conductive grease to the "plug
in" prongs to make sure they maintained good contact:

But if you are concerned, you can probably replace them all for
$100 in an hour.
As a matter of fact, I just had a 1965 breaker trip when a mouse chewed
through a wire and shorted it.



Did the rodent survive?
