whats to know. take your 7/8" (i think) crescent wrench and unscrew the poppets. drop them in the keg a long with the dip tubes. fill with your cleaner of choice and let it go.
Are you talking about ball lock disconnects or the ball lock posts on a keg. The two responses below deal with both of these. Essentially both are relatively easy to clean and I would do either of the two responses above that pertain to what you are talking about. Good luck.
