Dielectric Grease.

It's a rip-off, yes? I mean, it does nothing that vaseline doesn't do
for a fraction of the price. Or am I missing something?

 

Holts NoCrode.
Made for the job, my pint tin of the stuff is around 50 years old and
still half full, a little bit goes a long way.
Not sure if you can still get it though.

Sounds like the pint-sized tin of copper grease I bought at least 20
years ago, maybe longer.I think it will last longer than I will.

 

I couldn't be less surprised if Lisa Riley admitted to liking pies.

 

Wot he said, in my case it's a tube of Tamiya Switch lubricant from the
beginning of my r/c car racing days so that's got to be over 20 years old
now

Being Tamiya you'll probably still be able to get it as they still make
cars/kits with the mechanical speed controllers that need this grease to
make the contacts last a reasonable length of time. I use it on connector
blocks after they've been cleaned up, it helps keep moisture out of the
joint.
