Scrub the outside of the shell with a wire brush. Use firm pressure with a back-and-forth motion.
Fill your bucket 3/4 full with water. Soak the abalone shell for a few days to loosen any remaining debris. Allow to dry and then give it a final scrub with your wire brush. If it is raining outside, set the shells near a downspout and let the water spill onto them.
Apply a small amount of vitamin E oil to your fingertips and rub onto the inside and outside of your abalone shell to polish. Use a quick circular motion. If the shell has sharp edges, use a wash cloth. Reapply the vitamin E oil as needed.
