What make you think not to use light lubricant on the lens mt. surface?
In fact periodically I apply a drop of light machine oil on a Q-tip and clean it
over the lens mt surface (of the lens and body). You'll be surprise to see how
'dirty' the Q-tip is after cleaning the lens mt. surface.
For this maintenace, it will 'clean' the lens mt. surface as well as to reduce
frictions while mounting/dismounting your lens.
No harm trying.

I think you are more likely to damage the tripod socket on the body than the
lens mount (based on the relative diameters of the two), when you attach a
long (heavy) lens.
