Dialectric grease any thoughts

Tim I'd be very hesitant to use any oily substances on contacting surfaces. Even Caig pro-gold contains an oil which is supposed to prevent contact oxidation, but what sonic signature might this impart?
Under the hood of a car you'll find electrical contacts are wiped with silicon such as SilGlyde, and in that environment it makes sense to do that, but not with audio connections IMO.
Any oil or lubricant will attract & hold dust into the connection, causing importation of dirt into your connectors & even somewhat into the equipment itself. Solvents or lubricants might even cause material degradation, which is why Accuphase advises against using any cleaning solvents within their products & instead provides equipment with dust caps on all connectors. I still clean my cables & even the exterior surfaces of equipment contacts with an oil free solvent such as Kontact or Ultraconnect, but I never use anything containing oils or lubricants.

Sean I think you're referring to ConductoLube, a silver impregnated type of grease. I've used it successfully on large industrial DC battery wet cell systems; the connections between cells are made with open frame lead plated buss bar.
Cheech - rubbing alcohol is not even close to being the best contact cleaner; it contains lanolin, a contaminating oil, which as stated above is not desirable for our audio applications.

I'd heard that thay made a change in formulation of Ultraconnect but fortunately I have the old version; thanks for the report tweak. When I run out I'll stick with Kontact.

How did you get it off? Pure Denatured alcohol (without the lanolin, water, & other misc. contaminants of isopropyl junk) might be a good approach. I'll bet you were really scratching your head when you cleaned all the connections & got worse sound! What happened - what sonic signature occurred that you didn't want?

What's strange about that scenario Tom is that Ultraconnect etc. is supposed to *remove* all of the crusty stuff, leaving nothing behind. It seems that because the solvent did impart a sonic signature of its own, that in fact the solvent did leave some detrimental residue behind. It's NOT suppposed to do that of course.
Lucky for me I have 2 new full bottles of their original formula + the remainder of my original bottle. But I'll keep XLO's TPC in mind for the future in case I decide to try that vs. the highly recommended Kontact.
