It would be good to keep the Deoxit around. It can be used on any electrical connections. Can be put on
batteries, the contacts of most any
mod, even the threads of tube mods.
I use it on my exterior speaker wire connections, on the charger plugs of all my rechargeable things and even the connections of the wires in all my RC models. Wonderful stuff and can not hurt to use it where ever there is any type of electrical connection.
