Jay, I would first soak them in a water/baking soda solution to neutralize any acid trapped inside.
They I would use a bath of a mild detergent (dishwashing detergent is probably fine), shaking them through the solution to wash the gunk out. It might take several batches of water/detergent solution to get them really clean. The friction of the internal balls against each other and the inside of the chamber should scrub them well enough. Then I would soak/swish them through a bath of distilled water, with maybe a final flowing rinse of distilled water. You really want to make sure that no baking soda or detergent residue remains. If it does, it will find its way into the cells. Definitely not good.
