I have used Cramolin. It is definitely good stuff, though some of the mytic porperties ascribed to Cramolin by Hi-fi buffs are rather hyperbolic. I've seen teeny little bottles of Cramolin for sale in Hi-fi botiques for outrageous prices. If ones orders directly from Caig Laboratories, it is between $10 and $15 (US) for a couple ounce bottle. That should be a nearly lifetime supply. Be sure to get both types. There is a cleaner solution and a apreservative solution. The cleaner is very good; it does a much better job of removing crud than plain isopropyl alcohol. The preservative solution does an excellent job of preventing the cleaned contacts from re-oxidizing. My best Cramolin experience was with EEG amplifiers that have a DC gain of about 10,000. We used to have to unplug and replug the mil type connectors on a bank of 12 amps every day, or we'd get horrendous 60 Hz hum in our brain wave recordings. We cleaned and preverved the connectors with Cramolin several years ago, and have had no problems since. There is another nifty contact treatment maade by another comapany that the person who runs our phone system uses. The stuff comes in something that looks like a felt-tip marker and costs $40 a hit. The treatment consists of very, very tiny gold flecks that are encapsulated in a polymer coat. The coating on the gold is pressure sensitive so that the gold is exposed only on the mating surfaces of contacts. As such, one needn't worry about the possibility of bridging contacts, and the stuff can be safely used on very low level signal connectors. Sorry, but I don't have the name of the porduct handy.
