I use this stuff from Caig laboratories which is the same stuff, I believe, as Jack mentioned above. They have contact cleaners, lubes and restorers. It's the best stuff I have found and is used by a lot of techs and amateur radio people. NOT cheap! At work I have used their contact restorer on 40 year old, pitted power relays, with good results.

Their pitch LONG!!!! (has worked for me!):
1. FIRST, you must really clean contacts and connectors
WHY: Would you apply an enhancer or protectant on top of an oxidized/corroded surface? Would you apply gold plating over an oxidized copper based metal?
Simple contact "cleaners" wash away dirt, dust, and grime, but prove ineffective at removing oxidation and surface sulfides.
These tough contaminants actually attach to and become an integral part of the contact metal. This issue causes increased unnecessary service calls for covered warranty repairs that could have been prevented, translating into literally millions of dollars of lost revenue for service organizations.
The only true method of eliminating oxidation and surface sulfides is by chemical action and reaction, and that's what puts DeoxIT products in a class by themselves.
2. Next, you want enhancement - to improve conductivity
WHY: Why not improve performance, increase current flow, decrease heat and eliminate intermittents?
DeoxIT and DeoxIT GOLD are designed to improve the flow of electricity between metal surfaces. These products are initially non-conductive liquids, when subjected to an electrical field, DeoxIT and DeoxIT GOLD promote current flow. No short circuits will occur. In both states, DeoxIT, DeoxIT GOLD and DeoxIT SHIELD have resistances high enough to prevent short circuits.
3. Finally, you need long-lasting protection - for improved reliability
WHY: Once you have really cleaned a contact surface and enhanced its electrical properties, would you want to re-expose it to atmospheric contamination (humidity, salt, pollution, etc.)?
DeoxIT, DeoxIT GOLD and DeoxIT SHIELD protect metal surfaces in two ways. First they mechanically bond, on a molecular level, to seal the metal surface. Second, the thin film moves as the contact is disturbed by vibration or another contact surface. In effect, the product(s) re-coat exposed surfaces. This is especially important on equipment subject to vibration. Greases, silicones, polymers and PPE’s cannot reseal exposed surfaces. Once exposed or re-inserted they need to be re-applied.
4. Materials Compatibility: It's the key to the success of DeoxIT products
CAIG is committed to insuring product compatibility with new and existing materials and products. To accomplish this, we invest considerable resources and time working with hundreds of companies in many industries to insure that our products perform exactly as promised.
5. Ease of Use: Variety of convenient applicators
Since many applications require a different means of applying a treatment to contacts and connectors, we also offer nonflammable sprays, mini-sprays, pens, wipes, needle dispensers and our OEM squeeze tubes. CAIG is committed to the continued development of precision and convenient applicators for all of your needs.
6. CONCLUSION:
When you want to do general cleaning and remove dust, dirt and grime, any contact cleaner will do. But when you need to cure contact related problems, and dramatically improve equipment performance, CHOOSE DeoxIT!
