Love your DC design, and it will love you back. The best way to store your DC earrings are in separate ziploc bags. To clean, simply wipe with a damp cloth and mild soap. To preserve colour, do not store in direct sunlight. Clean sterling silver hooks periodically with a silver cloth, or by rubbing them gently with toothpaste [and wiping this off afterwards]. Please do not store flexible plastic polymer pieces on top of each other, folded, or in a very hot environment.
