I use the dishwasher on my balls and haven't had any problems so far. I personally don't use soap. I don't think it's necessary. The heat sucks out the oil and at that heat it will wash away fine without any extra help. Plus, as the oil seeps out it will also lift most of the stubborn dirt off the surface.
