DeoxIT on tube pins

Personally, the mechanical movement of pulling out the "appliance" (plug, tube etc) will remove the oxidation at the the areas of contact and renew the new metals to each other. Of course there are other manual or chemical ways to clean the pins/sockets and also to "bind" the area of contact.

What is “wrong” with using pro gold, once you have cleaned the pins with their solvent?

I use DeoxIT D50L for tube pins. Here is the kit that I use and works great:https://www.musicdirect.com/tubes/caig-vacuum-tube-survival-kit

@helomech,

That's a clever trick my friend. I wonder how the magic eraser + a contact cleaner on the ME would work?
