I think the term "lubrication" is a misnomer for tower cables.
Conventional lubrication with oil or grease should NOT be used on the cables
because it does attract dust and grit.
They should be "treated" with a product like PreLube. Prelube is formulated to
wick into the cables and provide anti rusting and anti corrosion.
It does not leave a wet or sticky coating like oil or grease.
The recommendations for lubricating the cables have been for "treating" the
tower cables and not lubricating them.
I have had to replace the cabling twice on my motorized crank up towers when
left dry. I live in the San Francisco bay area and rust corrosion
are big players in promoting a short life span to the cabling. 12 years ago I
began doing Prelube yearly maintenance on my cables and they still
look like new.
