BGnR-
I was generalizing; the implication was to avoid getting dust, and lubricants, and other crud in/on the shaft side of the fan. It was supposed to be a euphemism for all of the fan's bearing surfaces, be they ball bearings, sleeve bearings, or any close tolerance surfaces relative to the fan's moving parts. IOW, to simply be careful about gunking up the works by blowing particulate matter into places where otherwise less, or unrestricted motion could be impeded by its presence. I've seen many squeaky fans (and I'm sure you have, too) that have been "fixed" w/ a drop of lubricant, fail quickly thereafter by virtue of the lubricant acting as a magnet for subsequent dust. I merely tried to embellish the message to "clean carefully and properly" as part of a regular maintenance regime.
