They can be washed in warm water with a little dish detergent, using a small soft brush. Â But the very best way to clean down into every tiny crevice of a highly textured shell is an ultrasonic cleaner. Â I have two of them and it's amazing how much dirt and dust they can remove, even from a shell that has already been washed. Â They are also great for cleaning operculums.
