How to Clean Moissanite (the 2-Minute Method)
By Ryland, founder of Airwaves · Updated June 2026

If your moissanite has lost a little of its pop, don't panic — the stone is almost certainly fine. What dulls moissanite isn't damage; it's a thin film of hand lotion, soap, sunscreen, and skin oil that builds up on the underside of the stone, right where light is supposed to bounce. Clean that off and the sparkle comes straight back.
What you need
A bowl of warm water, a drop of mild dish soap, and a soft toothbrush. That's the entire kit. No ultrasonic machine, no special jewelry potion, no trip to a jeweler.
The two-minute method
Soak the piece in the warm soapy water for a few minutes to loosen the film. Gently brush the stone — front and especially the back, where the buildup hides — with the soft toothbrush. Rinse under clean warm water (plug the drain, or use a strainer, because we've all lost something down a sink). Pat dry with a lint-free cloth. Done.

Caring for the S925 silver
Sterling silver can oxidize and darken over time — that's normal, not a defect. A soft polishing cloth brings the shine back in seconds. Store your piece dry and away from open air when you're not wearing it (a little pouch or a zip bag works), and it'll stay bright far longer.
How often?
Once every week or two for a ring you wear daily; less for occasional pieces. The moment it looks a bit flat is the moment to do it. Two minutes, and it's back.
Questions
Why does my moissanite look cloudy or dull?
Almost always a film of lotion, soap, and skin oil on the back of the stone — not the moissanite itself. A warm soapy water soak and a soft brush restores the sparkle in minutes.
Can I use jewelry cleaner or an ultrasonic on moissanite?
Warm soapy water and a soft brush is all you need and is the safest option. Moissanite is hard and durable, but for plated pieces, skip harsh chemicals and ultrasonics to protect the plating.
Will the sterling silver tarnish?
It can oxidize over time — a soft polishing cloth fixes it fast. Store it dry and sealed away from air between wears to slow it down.
