I just inherited some classic speakers, they sound incredibly good with my amplifier.
The contacts for the speaker cable on the back are a little corroded, they're copper and steel.
What can I use to remove the rust and corrosion and make them shiny and pretty again?
I would just trim a bit of the plastic cable back, then nip the rusty bit off with some wire cutters. Tada, shiny cable underneath.
The actual contacts on the speaker, not the cable.

I have shiny new cable.
you can get new speaker terminals for dead cheap
any good car audio shop will sell them for like $3 or something or if you are in the UK its usually like £2 each pair.
I don't want to mess with them since they're worth so much, I could screw up.
If I keep the original parts it'll keep the resale price up too.
Dont worry its simple to replace them i worked with this stuff for years :).
You would have to have downs syndrome to fail at it.
There might be screws holding them on
if so then unscrew them pull it out if it dont come out very far resort to solution B
if it does then there should be two wires (usually black and red) cut those and throw away the old terminals then solder the wires to the new terminals then pop it back in make sure you put glue around the hole to seal them.
solution B
if there is no screws on the terminals
all you do is unscrew the woofer (the large speaker usually at the bottom) then when that is out look towards the back of the box there will most likely be a circuit board called the crossover unscrew that if you cant see the back of the terminals coz they are behind itthen cut the wires, unscrew, solder wires to new term's, put back in, screw crossover to where it was then you are done :)
JUST DONT RUSH IT because then there is more chance that you will screw it up.

For nice old stereo stuff, depending on what type of contacts they are, whether they are flip down, or locking, or screw post contacts, I take a thin wire brush for cleaning plumbing and just run that back and forth to try to get the corrosion off. If that doesn't work, you will need to sand them off. That's why they don't use steel anymore for contacts, it was believed it improved sound quality but it just corrodes over time. Copper has a way better hold up. If you're forced to sand it off, you'll have to get really creative, because you're working with such a small thing.
gold plated terminals are better :v:
