What is the wrong way or a risky way to store a lens?
Is the effect of heat going to soften the lubricants and allow them to
flow onto the blades?
Where in the lens does the oil come from?
Can the oil be cleaned off the blades? and how hard is this to do?
Thanks

Perhaps the short answer is to say store your lenses nose down. That's how
they come in OM lens cases.
This topic comes up periodically. It's more of an issue for Nikkors, as I
understand it, and since there are more Nikkorheads than Zuiks, the topic
may drift here for that reason. A Nikkor is opposite the Zuiko in being
more "at rest" stopped down. (A Zuiko rests wide open.) Since it
therefore makes sense to store a Nikkor stopped down, the question arises
as to which way best to store it to prevent oil migration out onto the
blades. (That seems to be nose down, if you're curious.)
I don't think it matters with a Zuiko. I store mine nose down as it forms
a broader base.
There is lubrication in a lens. Perhaps someone can give you a technical
explanation as to how it gets on the blades. I'm guessing that heat can be
a culprit, but I don't know if it is the only culprit. I think a
technician can clean oily blades without difficulty. I wouldn't personally
attempt to disassemble anything but a throwaway lens, but some people are
comfortable doing some fiddling with the simpler lenses like a 50/1.8.
