cleaning your spade connectors

oddly enough, you can use Pepsi to do this.

Its a trick mechanics use to remove the corrosion off of the battery terminals in vehicals. Works pretty well too.

Just put the ends in a glass of pepsi for about half an hour, then use a wire brush and clean them.

wipe them off, and yer good to go.

I will probably get shot for that reccommendation, but if you want to save a few bucks, it is a great way to go.

There are also a variety of commercial products at ACE Hardware and HOME DEPOT if you dont want to use pepsi.

I use Barg's Rootbeer or Liquid Plumber, then flush with plenty of water !! ......................... Just kidding, really a small wire brush and some Caig Pro contact cleaner would work well.

For speaker cable spade connectors I would avoid using any wire brush to remove tarnish since this will always leave scratched surface and remove silver plating.

Instead dip in some Tarn-X available almost any home improvement center which will instantly remove tarnish, wipe clean then follow with your favorite contact enhancer like Kontak or Caig Pro Gold etc.

BTW I use this method on my own AP speaker cables with massive T1 silver spades.

Slappy,
I guess you don't drink Pepsi nor recommend to consume it:-)
I personally consume Aquafina or Poland Spring.

Do not use Tarnex on ANY plated metals, period. It will corrode the base metal and destroy your connectors in a very short period. Trust me on this. Tarnex can only be used safely on bare copper or silver and the connector must be rinsed thoroughly with water afterwards. Do not use this product on brass either.
