I agree with Don on this. For years, I have cleaned my battery connections and coated them with petroleum jelly before connecting them. The small amount of resistance from the lubricant is much less than that from the corrosion that soon develops in the connections without it. I've never had a problem with this method. (I stay away from grease with chemicals in it.)
Caig Deoxit is good stuff. I used some today in my car. It is spendy in U.S. as well. I'm not familiar with Servisol.

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. 73, Don W3FPR On 6/17/2013 2:31 PM, makid...@gmail.com wrote: > 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!!! > > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
