PVD coated steel or titanium jewelry requires a bit of extra care. It’s important to keep the PVD coating intact, so it’s important never to use any harsh chemicals (such as alcohol) on the PVD coated jewelry. Use purified or distilled water and mild germicidal / anti-bacterial soap. Don't soak in any chemicals or solvents including alcohol. It’s important to take care of your jewelry to prevent PVD coating from chipping.
