I don't know for sure, but I would think that if you did the initial stripping wash with Charlie's you'd be fine. If you're using Charlie's for diapers and something else for other loads, I would think that the diaper loads would work to keep the machine relatively buildup free.
I use Charlie's, but use it for everything, so I'm just guessing here.
