Cleaning and Caring for Your Accessories
Aluminum is a great metal for pet tags. It doesn't oxidize or tarnish, and its water safe. Plus it's so lightweight, your pet won't even notice it's there! Although aluminum is water safe, this can cause the black ink to fade in your hand stamped text and designs.
Both brass and copper oxidize to a dark finish. You can restore your tag to it's original, shiny appearance with a jewelry polishing cloth. You may apply a thin coat of jewelry wax to your piece. It will prevent it from tarnishing, but it will wear off - so you'll need to reapply every so often.
