Best Grease for disconnects?

A:

We can recommend three possible solutions.

1. For surfaces with slight oxidation on the metal surfaces, apply our DeoxIT® L260 Plus Grease Spray (Part No. L260DNp) – which does both, removes oxidation slowly over time (without harming metals & plastics), improves current flow and lubricates surfaces.
2. If the metal surfaces are severely oxidized, first apply the DeoxIT D-Series (Part No. D5S-6 or DN5S-6N), then apply one of our DeoxIT L260 Grease with particles. For example; if metals on lugs are copper, use Part No. L260Cp (with copper particles).  If lugs are aluminum; use Part No. L260Ap (with aluminum particles).  If lug material is unknown or a mixture, use L260Qp (with quartz particles).  The particles help break up the oxidation and corrosion.
3. If the metal surfaces are severely oxidized, apply one of our DeoxIT L260D Grease with particles. For example; if metals on lugs are copper, use Part No. L260DCp (with copper particles).  If lugs are aluminum; use Part No. L260DAp (with aluminum particles).  If lug material is unknown or a mixture, use L260DQp (with quartz particles).  The particles help break up the oxidation and corrosion.
