You will have to degrease the rings in the back mount, but don't rub too
much as the black coating on the rings may start to come off and thats what
makes the rings slippery.
Then when thats finished, disassemble the front of the lens and take the
blades & ring plate out.  Degrease these, and the interior of the lens
barrel  and rebuild.
