Cleaners

The cleaner I use is F2 contacts, made by KF, a local french subsidiary of CRC Industries.

Cleaners today are much better than those built 10 or 15 years ago. Maybe the fact that freon solvants and propellants are phased out boosted the research. Good for us users.

At the beginning of the '90s, I had problems with them in airtight LRM (modules) for submarines: the layer of oil deposited onto the contacts was soon decoming very viscous and non-newtonian, and after a while (some months), ecah time the LRM was plugged/unplugged, a thicker and thicker layer of goo was accumulating after having been displaced ny the incoming contact...
Until the goo spread until able to slip under a contact the next time you unplugged it...
It was shown that the culprit was the glue used to bind together in each LRM its two half-boards sandwiched with the thermal Copper/Invar/Copper board... It emitted vapors that dissolved and reacted onto/with the cleaner's oil layer... Mammama...

No, these problems are gone, and the cleaners' oil layers don't ever anymore attract aerial dust.
