Sorry for the late reply, I forgot that I posted this... Anywho, you need to degrease everything thoroughly, then boil in distilled water. You'll see the patina turning black almost immediately, but I'd still boil for about 10-15 minutes, maybe more if the brown buildup is thick.

Blow the parts dry with compressed air while they are still hot, then use a thin penetrating oil to protect them. I use Brownells "After Bluing Oil" http://www.brownells.com/gunsmith-to...-prod1086.aspx ), it will soak in everywhere and dry to a thin, waxy film. It's the best stuff I have found for protecting gun parts, you don't have to wipe it off or anything. Just shake off the excess and let it dry.

BTW: This method works quite well for refreshing case hardening as well. Case hardened parts are a royal PITA to blue, but it they have a brown patina you can make them look pretty darn good just by boiling them.
