If your read the book "CLEAN YOUR SHELLS" you will see the use of Kitty
Litter, which is not as heavy as sand, and does a very good job. I take
some with me when I have no way to clean my shells on trips. If you can
keep them refrigerated that really helps. Then put them in the litter or
put litter in the aperture.
