The idea of using oleic acid on electrical contacts worries as it
must become conductive under enough voltage.

What do you mean "must become conductive"? Do you mean that the oleic
acid becomes conductive, or perhaps the contact cleaner? Unlikely
because the oleic acid will attack copper and therefore must be washed
off by something after its used to clean the oxides, sulphides, crud,
dirt, tar, and oils off the contacts.

The Deoxit I bought a few days ago must not contain any of the oleic
acid. Not mentioned on the can. This is Deoxit D5. The can says it
protects surfaces so doubt this is a copper eating compound.

The directions say to spray and activate the knobs. Then give it a
short spray and wait 2 minutes before turning the equipment on. I guess
that the wait time is to make sure any thaing that burns has evaporated.
There is no mention of cleaning it off, but really should be left on the
contacts from the way I read it.
