Tungsten Carbide Cleaning:
Your Tungsten Carbide or Ceramic ring is very easy to care for. They doesn't scratch easily and are tarnish-resistant. That being said, it is still important to following a few simple steps to help ensure your new wedding band will look spectacular for years to come.
How to clean: To clean tungsten/ceramic carbide rings, simply soak in a mild soap solution for a couple of minutes, rinse and wipe dry with a soft cloth, removing any fingerprints and smudges.
Tungsten Carbide rings with sterling silver inlays may tarnish over time, in that case, use a simple polishing cloth or a cheese cloth to polish. Although Tungsten doesn't scratch, it may look it has been scratched when the ring is accidentally rubbed up against something else with metal and a part of the material has attached itself to the surface. In that case, you can use a soft brush to gently remove the foreign materials.
How to clean: You can use a half-ammonia (you can use Windex), half-water solution and soak for a few minutes, rinse and dry with a soft cloth.
