2026 Ultimate Guide to Cleaning Moissanite: Sparkle, Oil Slicks & Metal Care

Let's learn this lesson of Sparkle, Oil Slicks & Metal Care about Moissanite CleaningYou chose Moissanite for its fire that explosive, rainbow-colored brilliance that outshines even the finest diamonds.

But a few months into wearing your ring, you might notice something concerning. Maybe the stone looks a little milky. Maybe it lacks depth. Or perhaps you see a strange, multicolored film on the surface that looks like an oil stain on pavement.

First: Don't panic. Your Moissanite is not broken, scratched, or defective.

Moissanite is a Forever Stone (9.25 on the Mohs Hardness Scale). It is chemically stable and does not permanently change color or get cloudy internally.

It is simply dirty. And unlike diamonds, Moissanite has specific cleaning needs. At La Pretti, we have combined everything you need to know—from basic washing to removing the dreaded Oil Slick—into this single, definitive guide.


Why Does Moissanite Look Cloudy?

To clean it properly, you need to understand the science.

Moissanite is composed of Silicon Carbide. While extremely hard, Silicon Carbide is lipophilic, meaning it attracts fats and oils. Every day, your ring acts like a magnet for:

  • Hand lotions and sunscreen.

  • Hair products (hairspray is a major culprit).

  • Natural skin oils.

  • Kitchen grease.

Over time, these oils build up on the facets, creating a smear that blocks light from entering the stone. This kills the sparkle and makes the stone look dull or cloudy.

Moissanite Oil Slick: If this oil buildup is left for too long, it can oxidize and create a stubborn, metallic rainbow film on the surface. This is the #1 complaint of Moissanite owners, but it is 100% removable.


Weekly Sparkle Routine (General Maintenance)

For 90% of dirt and grime, you don't need expensive commercial cleaners. The best solution is likely sitting next to your kitchen sink.

Dish Soap Method:

  1. Bath: Fill a small bowl with hot water (as hot as your hands can tolerate) and a generous squirt of liquid dish soap. (Blue Dawn is the industry favorite for its degreasing power).

  2. Soak: Drop your jewelry in and let it sit for 15–20 minutes. This softens the hardened oils.

  3. Scrub: Use a soft-bristle baby toothbrush to gently scrub the stone.

    • Crucial Step: Scrub the underside of the stone (the pavilion) and around the prongs. This is where dirt gets trapped against your finger, dulling the stone from the inside out.

  4. Rinse: Rinse thoroughly under warm running water to remove all soap residue.

  5. Dry: Pat dry with a lint-free cloth or use a hair dryer on the "Cool" setting to prevent water spots.

Deep Clean (Removing the Oil Slick)

If you washed your ring with soap and it still looks yellow or has a rainbow stain, soap isn't enough. You need to physically break the bond of the stubborn oil film.

Secret Weapon: Silver Polish. Wait, isn't that for the metal? Usually, yes. But because Moissanite is so hard, mild silver polish is the only thing that removes the oil slick without scratching the stone.

How to do it:

  1. Use a Silver Polishing Cream (like Wright’s) or a high-quality Silver Polishing Cloth.

  2. Rub the stone itself firmly for 1–2 minutes. The friction lifts the oxidized oil film.

  3. Important: Wash the ring with soap and water immediately afterward (Method 1) to remove the polish residue from the crevices.


Caring for the Metal (Gold vs. Silver)

While the Moissanite stone is virtually indestructible, the metal holding it is not.

If Your Ring is Gold (14k or 18k):

  • Avoid Chlorine: Never wear your ring in a swimming pool or hot tub. Chlorine chemically attacks the alloys in Gold, causing the metal to become brittle. This can lead to prongs snapping and losing your stone.

  • Avoid Bleach: Cleaning the house? Take the ring off. Bleach can pit and discolor gold.

If Your Ring is Sterling Silver:

  • Expect Tarnish: Unlike gold, silver reacts with oxygen and turns black (tarnish) over time. This is normal.

  • The Fix: Use a Silver Polishing Cloth on the metal parts once a month.

  • Storage: When not wearing it, store silver jewelry in an airtight Ziplock bag. This cuts off the oxygen supply and prevents tarnishing while you sleep.


La Pretti Frequently Asked Questions

Q: Can I use an Ultrasonic Cleaner?
A: Generally, yes. Moissanite is tough enough to handle the vibrations. However, if your ring features Micro-Pavé (tiny diamonds on the band), we recommend avoiding ultrasonics. The intense vibration can shake loose these tiny stones if the setting is delicate. Stick to the toothbrush method for pavé rings.

Q: Can I use Vinegar or Windex?
A: We don't recommend it. While it might clean the stone, vinegar is acidic and can damage certain porous gemstones (if you have other rings nearby) or discolor plated metals. Dish soap is safer and more effective at cutting grease.

Q: Can I wear my ring to the gym?
A: We advise against it. While the stone won't break, gold is a soft metal. Lifting heavy weights can bend the shank of your ring out of shape (known as flat tire) or loosen prongs.


Keep the Fire Alive

Moissanite is a low-maintenance gem, but it loves a little attention. A simple scrub once a week can transform a dull ring back into a blindingly brilliant showstopper.
