Instructions
Cleaning Empty Shells
Fill a bucket with one part bleach and 10 parts water.
Place the shells inside of the bucket so that they are covered with the bleach and water solution. Soak for at least 24 hours.
Empty the bucket of bleach solution. Remove the shells and rinse each one carefully with water and dry.
Cleaning Shells with Animals
Add shells to a pot of room temperature water.
Bring the water to nearly boiling, then remove from heat. Cool gradually so the shells don't crack.
Shake, flush, or pick the animal from the shell with a sharp instrument.
