Would Ivory bar soap or some other natural hard soap (Grandma'a Lye
Soap?) work? Whereas the chained hydrocarbon barriers also provide
lubrication, they may be permeable to oxygen. Corrosion. Soap being a
modified chained hydrocarbon will give lubrication and the amphipathic
charged end or electronegative end may become hydrated and the
combined electronegativity provides a second barrier to Oxygen
diffusion with a sort of negative Van der Waals force. Then again, it
might just freeze a second one solid. I'd try hemp oil before anything
else. It's good or best for almost every human need, maybe its oil
will show the same general property that all of its other properties
share, they're beneficial.

Lye is very alkaline. Corrosive and dissolving. Soap is by chemical
definition the sodium or potassium salt of a long-chain fatty acid (yes
acid). In addition, it is a detergent, so it will "wet" surfaces.

If you are thinking of a grease or oil, then that may be fine, but make it
an acid-free vaseline.
