Q. What should I use to clean connectors?

Caig Deoxit is recommended for cleaning connections, though it’s worth noting that there are variants for different metals, including for gold connectors.Caig Deoxit is recommended for cleaning connections, though it’s worth noting that there are variants for different metals, including for gold connectors.I have recently been reorganising my equipment and making new cables. Most of my connectors and cables were bought second-hand, and I’m going through them all to make sure they are as they should be. The connectors are all Neutrik-branded, so I expect they were well built, but some are blemished and I wonder if you could give a little advice as to what would be the best way to clean the connectors. If you could recommend any particular solvents that would also be appreciated.

Additionally, the manual for the Millennia HV 3D recommends that one uses gold-plated connectors with the gold-plated connectors fitted in the machine. I don’t have many gold-plated connectors — is this important?

SOS Technical Editor Hugh Robjohns replies: Deoxit from Caig Laboratories is the best cleaner for audio connections — the D5 version is the usual recommendation, but G5 may be better for gold connectors. Regarding the question about gold connectors, note that gold is a very soft metal and thus it can be eroded through friction. For that reason, it is recommended — and a good idea — to use gold-plated connectors to interface with a product’s gold-plated sockets. And if you can afford a Millennia HV3, then there’s really no excuse for not being able to afford some new gold-plated XLRs!
