Your tungsten carbide ring requires essentially no care. If your ring is 100% tungsten carbide high polished your ring will retain its luster and polish forever. A soft cloth will eliminate fingerprints and smudges and a little bit of water can help wipe away any liquids that may have dried on your ring.
All tungsten rings with sterling silver or gold inlays will tarnish and need to be polished up over time. We suggest using a tarnish removing liquid like TARN-X.
Avoid cleaning your ring with harsh chemicals, abrasive sponges or compounds, and DO NOT LEAVE IN THE ULTRASONIC CLEANING MACHINE FOR MORE THAN A MINUTE. All of these cleaning methods can potentially damage the surface of your ring.
