I have several dozen silver earrings. How can I keep them from tarnishing? Is there a spray that could seal them?
For tarnish resistance, store your jewelry in plastic top zip (or side) bags. This will limit the jewelry's exposure to the air which causes metals to tarnish. Also consider placing an anti-tarnish strip in each bag for added tarnish-resistant benefit.
To clean your tarnished earrings, use a liquid jewelry cleaner or ultrasonic jewelry cleaner. Once all of your earrings are cleaned, you can apply a clear spray fixative to them to help extend their shine.
