GS5556 is very accurate in his statement. Silver Oxide is fine, but exposure to sulfers can be detrimental, though probably no nearly as bad as oxidized copper. Cleaning up your spades once in awhile is a good idea. If I can't clean them up with something like Pro-Gold, I give them a buff with the very fine emery paper you can find on some good finishing fingernail files...I like the padded kind.
Audioengineer is right about how a better connection can be made with proper spade terminations. They also save you the hastle of restripping the cable if you disconnect it and don't want a lousy frayed connection. If you need to save some money and not buy them terminated, silver or a heavily silver clad cable will work out much better than a copper one that can quickly oxidize.
