When I went to A&P school (oh so many years ago) they told us that
aircraft cables should NOT be lubercated.

What did they say about lubricating sheathed/enclosed cables such as
throttle, carb heat, and mixture? My experience is that, unless they
have an integral nylon sheath, they do need to be lubricated but LPS-2
in not a good choice.

BTW a review of AC 43.13-1b found this:


7-150. CORROSION AND RUST PREVENTION.
To ensure a satisfactory service life
for aircraft control cables, use a cable lubricant to
reduce internal friction and prevent corrosion.

My poor experience with LPS-2 on aircraft control cables was with the
enclosed throttle cable of my PA28-180.

I have never lubricated open control cables that run over pulleys
although AC43.13-1b does seem to say that is appropriate in some
circumstances.

Most "marine greases" are designed to be water insolvent, resist
washout etc. in bearings. Water soluble lubricants are most commonly
used in tooling/cutting applications. What exact grease are you using?

Most people would just use a common hardware store lithium soap
grease. It's white does not make much mess and cleans up well with a
dry towel. Lithium soap greases vary in their water resistance, but
I'd expect the "marine" variants to be at the more water resistant
end.
