I would use Happy Camper Extreme. It is specifically made for cleaning the tanks. You will need one container for each tank. You put the container into he tank, fill it to half, and then drive around for while and dump when you get to your destination. Many people have had success with it.
We also use the regular Happy Camper in the black and grey tanks regularly.
