I'm interested in this, since my daughter's bike just hangs from the ceiling except when she visits once a year or so. But I live right by the ocean, and the air is always humid and salty.
I wonder if you should coat all the metal surfaces with WD-40? That's what it was designed for (http://wd40.com/about-us/history/):
, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers
for use in the aerospace industry, in a small lab in San Diego, California.
It took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40®
—which stands for Water Displacement perfected on the 40th try—is still in use today.
