How do you sterilize for reuse in hydroponics?

To sterilize (also known as Clay Balls) for reuse in hydroponics, wash off any plant debris, soak in a 10% bleach solution for at least 10 minutes, rinse thoroughly, then let dry completely. This will remove any pathogens and make them ready for reuse.
