Take it to Royal oak car wash and when there is no one around use the pressure washer to spray out all journals.  Get every passage ,nook and cranny and that should be good.

i just finished scrubbing my case last week, and highly recommend brakekleen for serious gunk, a power wash and a lot of elbow grease.  i've also heard a quick wash with mild detergent prolongs case life.

have fun scrubbin'  :P

If you don't have access to a parts washer, then pick up a few cans of Brake Kleen.  Its a good solvent and relatively cheap compared to carb cleaners and the like.  

To clean the passages, nothing works better than bronze-phospher brushes for cleaning gun barrels and an old cleaning rod.  You'll need a few different sizes and there only a few bucks at a sporting goods store.  Shoot a blast of cleaner into the passage and work the brush back and forth 6-8 times.  Flush with solvent and shine a light into the passage.  If your not sure its clean, rinse the brush and repeat.  When you pull the brush out, see if its still getting dirty with crud.  It's a good indication how clean its getting.  

I just did what I thought was a pretty clean crank.  The cross-drilled passages contained a fair bit of \"mud\".   I was amazed that much crap builds up in there.
