I agree with Brian. Take the corrector off, noting the marking. And wear
gloves so that you dont put oil on the corrector or secondary. While the
corrector is off, use compressed air to blow any accumulated dust off the
primary, secondary, and inside corrector. If need be (of course, ONLY if
need be) you can clean your optics while they are exposed.
