I have tried this years ago, but your best bet is a complete dismantle & reassembly with a complete & cleaning as the oils & grease will just keep migrating onto the blades.
If the gunk is light, remove the lenses & cut some thin strips of paper 1/8 " as needed & 1/2" length. Take the strips & bend at a right angle, dip in a solvent & slide between the blades. Keep fishing clean strips in & out until the blades come clean. Take a hair dryer to the shutter assy. & lightly warm it up to remove any moisture before trying to activate the unit. This would usually get a shop through a warranty period, & the customer would not know any better. I did not like this procedure, but it is nice to know. The other procedure mentioned elsewhere on this site could cause some trouble. If you dunk the shutter in lighter fluid, it cleans all the grease off & if the blades or aperture have a residue on them when you activate them a partial vacuum could damage the pivot points. The pivots on the aperture blades are staked in place brass. The blades on both are a spring steel that is very thin. It does not take very much too damage them.
