Since your PL259's aren't aluminum, the answer is no. Anti-oxidants are used to prevent oxidation of wire or metal electrical connections of aluminum and/or copper. Read the label - it'll tell you what the target metals are. The "junk" on your center conductor is an oxide; which one depends on what your connector material is. If you're using silver PL259's, then it's no problem because silver oxide is a conductor. If you're using the cheaper nickel plated ones, that's problematic because nickel oxide is not a conductor. The best thing to do obviously is to use silver connectors but your problem is probably due to inadequate weatherproofing. The key to success is to use Scotch 33 or 88 electrical tape (not the '3 rolls for a buck' stuff from the local hardware store) and have a layer of vaporwrap over it and then another layer of tape over the vaporwrap. The last thing to keep in mind is that the last wrap should go UP so the tape layers overlap like the shingles on your roof. If the tape is wrapped down, the tape just channels water into the connector. If you do this, when you open the joint years later the connectors will look just like new. WARNING: DO NOT put CoaxSeal directly on a connector. If you do - you'll never get it off and the connector will be a fairly useless wad of junk. For anyone interested in practical tower and antenna contruction topics like this, the TowerTalk reflector is a terrific resource that you may want to subscribe to. Let me know if you want subscribe info. Questions like this are probably more appropriate for TowerTalk than this Force 12 antenna reflector.
