My experience with Deoxit Gold (100% solution) was negative; I applied a small small quantity on my gold plated connectors and the sound became cold, harsh; after some days I cleaned two times with IPA 99% and the sound returned to pre-Deoxit state. If You have gold or rhodium plated connectors please just use IPA every six months. Deoxit Gold contain a corrosion inhibitor and act like an insulator, so in no way it can improve electrical connections. If You have oxidized connectors, change connectors or clean with a toothbrush and a lot of IPA. Caig write in their pdf that quantum tunnelling is the mechanism of action of the Deoxit Gold, but they don't explain in details.
