I did a search and nothing came up.  Perhaps this has been covered before.  I've been trying to use Chem Dip (Berryman's) to clean up some carbs but they are not coming out well.  Often there is a blackish deposit that looks bad.  Maybe there is another process after ChemDipping they need to go through, or maybe I am leaving the parts immersed too long.   

Are ultrasonic cleaners the method of choice these days?  I heard some time ago Harbor Freight had an ultrasonic unit.  Anyone using it?
