Please do not shower or swim with earrings on. Although polymer clay will not hold or absorb water, the hardware could tarnish if earrings come in contact with excessive moisture much too often. When not wearing the earrings, store them in a box or pouch in a dry place. If you get make up on your earrings, use a little acetone on an ear bud and gently go over the affected area to lift the make up off. Brass earrings can be easily cleaned with Brasso or your good ‘ol tomato ketchup/ tomato juice. Using an earbud, apply generously to the brass component and leave for about 15-20 mins before rinsing off with warm water. Pat dry with a clean towel and voila! They will shine as new.
