The MSDS says Caig DeoxIT is 95% naptha and 5% "trade secret."
Internet lore claims the 5% "trade secret" portion is largely linoleic
acid (from flax seed).
GC Electronics has a much less expensive similar product called
"DE-OX-ID" which is 60% Aliphatic Hydrocarbon, 35% Kerosene with the
remaining 5% being more hydrocarbon solvents according to its MSDS. It's
what I use.
Naptha is light end hydrocarbon, with both linear and aliphatic chains.
Lighter fluid is mostly naptha by the way.
Last bottle of DE-OX-ID I bought cost about $6 for 2 oz in a brush
applicator cap bottle. It's gone up a couple bucks since then, and there
may be a problem with additional shipping surcharges since it's
flammable. (Earlier this year, I was charged $10 to ship a 2 oz bottle
of red Glyptol varnish for that reason.)

Don,
Nice suggestion. I have worked on lots of corroded stuff over the years for
outdoor, very nasty weather situations. I like your solution. I have used
DeoxIT in the small brush bottle with fabulous success. The connectors appear
very clear once applied, but there is no content listed on the package as to
what chemistry is used to actually remove the oxide. There are lots of
chemicals that work, but nothing like adding a little inhibitor (oil) and scrub
the connector by reseating it few times. I will continue to use DeoxIT until I
find out its actual content, thinking it actually does something, plus, for the
uses I have, it is relatively cheap in my shop. I sure would like to know
what is the 100% concentrate on the package.

Jim,
I have used several cleaning/lubricating compounds on electrical contacts with
success over the years. The easiest is to use a light coating of any light
lubricant ( similar to 3 in 1 oil) on the male pins. The insertion and removal
of the contact surfaces in the presence of the lubricant will wipe away
corrosion at the mating points, and the residual lubricant helps to discourage
further oxidation.
I know I may take some flak from those who are hesitant to use anything other
than compounds recommended for electronics, but I have never experienced any
difficulties. Just apply the lubricant sparingly and mate then disconnect the
pins a few times for best results.

Hi All
Elecraft Tech have advised to try cleaning the contacts in my K3 with Caig
Deoxit, problem is here in the UK it’s really really expensive, like it should
some in a solid gold tin!!!
So my question is will Servisol Super 10 be a good substitute for Caig
Deoxit, I know servisol has been used in service rooms for many many
years for removing tarnish and lubricating contacts
Whats your thoughts?
Looks like i’m in for a K3 strip, clean contacts and rebuild, shame these
contacts are such a weak point on such a great transceiver!!!
