Instructions
Fill a sink or bucket with enough warm, soapy water to cover the sticky koosh balls. Since these balls get a lot of handling, use antibacterial dishwashing liquid or antibacterial soap.
Swish the koosh balls around in the water, and massage them so the water gets all the way down to the center. Let them soak for a few minutes, depending on how dirty the balls were.
Rinse the balls thoroughly, until all soap and debris is gone. Allow the balls to air dry on a rack or drainer, so the air circulates all around them.
Put a small amount of cornstarch in a plastic or paper bag, add the koosh balls and shake, so that each filament is covered with a light dusting of powder. Remember to shake off the excess cornstarch before playing with the balls.
