What cleaner do you use for cleaning the threads, contacts, electrical parts of your flashlight?

@ NeutralFan:

Thanks for that ‘SuperLube Compatibility’ chart. Seems compatible with Buna N ’O’rings (NBR) which would be the common material The O-Ring Store (not to be confused with Buna S).

Was using in the past and only had problems with some of the thinner / slacker ‘O’ rings, which I attributed to oversized rings. Now realize they may have been silicone-based. Currently using Echlin ML-2 which is also a silicone-based grease with amorphous fumed silica (thickener and binder). A find in a flea market as the original Nyogel is very expensive.

AFAIK, silicone type ’O’rings are stretchier (when black). Any other method of recognizing?

Nyogel is available at your local Ford dealer for 17 dollars. 4oz tubes = 113.4g. The Ford electrical grease is Nyogel 760G
