thanks to the people who answered my earlier question regarding the F280 and
the OM4. I have another OM question...

Sorry if this has been discussed before,
I have read in an earlier post that "the aperture blades of a lens can get
oily when the lens is stored in a certain way". I myself have seen quite a
few oily blades in my days.

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
Tim
