As far as I know, just the black tank. The gray tanks should not have any solids in them that need extra help to clean out. I always flush my black tank at least twice and sometimes three times. After the initial flush I close the black tank valve and rinse for three or four minutes as that amount of water accumulating in the black tank should not over flow your toilet. Best you check you own though. I then open the valve again to drain the tank. The first time I did that I was amazed at how much more waste was left after the initial flush, and that is using a breakdown additive. Don't get your hopes up though about cleaning your sensors. You name it, I have tried it, and they remain securely stuck at 75%.
