Instructions
Place the seashells that have dead tissue in a pan of water. Bring the water to a boil and allow the shells to boil for 5 minutes. Remove the shells from the water and rinse under cold, clean water.
Mix a 50/50 solution of water and bleach. Add 1 tablespoon of dish detergent to the mixture. Place the seashells in a bucket and pour the bleach solution over the seashells. Allow the shells to soak overnight.
Scrub the seashells with a stiff brush to remove any algae or other debris from the surface. If the shell does not clean easily, soak it for another night in the bleach solution. Remove the shell and clean with the brush again.
Rinse the seashells in clean water and set them in the sun. Once the shells are completely cleaned and dry, set the shells on newspaper.
Wipe the seashells with mineral oil to bring out the colors and add a shine to the surface. Wipe off the excess oil with paper towels. The shell should not feel oily when it is thoroughly wiped down.
