In response to the questions about shark liver oil, supposedly the Japanese are the masters at making the version that works for audio. The tests I have conducted show no signs of mucking up or changing consistency over time. Eventually all audio connections oxidize and the Caig , shark liver oil, Cramalin or whatever must be removed, the connector cleaned and begin all over again.
As for performance, the Deoxit cleaner is great, but I still have not decided between the Caig gold and the shark liver oil as a preservative to slow down the oxidation process. They both have a sound compared to no preservative, and it seems to vary depending on the connection. The connection at a phono stage for instance is always better with shark oil, and speakers are always better with Caig gold. Every other connection seems to be a roll of the dice.
