Caig Laboratories (<!-- m --><a class="postlink" href="http://www.caig.com">http://www.caig.com</a><!-- m -->), the makers of DeoxIT products, recommends that a cleaner without solvents such as their DeoxIT 100% spray (D100S-2) be used to clean vintage potentiometers. It seems that phenolic, and perhaps some other materials commonly used at the time, are very porus, and that conductive solvents can be come trapped for extended periods of time in porus materials. DeoxIT D100S-2 contains no solvents, only their deoxidizing solutions. See their recommendation at: http://store.caig.com/s.nl/ctype.KB/it.I...ategory=21

I now use only DeoxIT D100S-2 on tube radios. I use it where needed as a contact cleaner, and I use it on noisy pots. It seems to work very well for me.
