If your jewelry has lost its shine or your eyeglasses still look smudged after cleaning, you’re not alone. Scrubbing by hand or using chemical cleaners doesn’t always work—and it can even damage delicate items. That’s where ultrasonic cleaners like the Magnasonic CD2800 come in. They make it easy to clean your valuables using just water and sound waves—no abrasive brushes or harsh solutions needed.

In this guide, we’ll explore how ultrasonic cleaning works, walk through the key features of the Magnasonic jewelry cleaner, and show you what it can safely clean—from rings and dentures to eyeglasses and coins. You’ll also get real user feedback, pro cleaning tips, and a clear answer to whether this cleaner is worth buying. Let’s break it all down, step by step.

What Is an Ultrasonic Jewelry Cleaner?

How ultrasonic cleaning technology works

An ultrasonic jewelry cleaner uses high-frequency sound waves to clean small, delicate items. When turned on, the machine sends sound waves through water, creating tiny bubbles in a process called cavitation. These bubbles pop quickly, lifting dirt, oil, and grime from the surface of jewelry, glasses, and other items.

The Magnasonic Professional Ultrasonic Jewelry Cleaner uses this method to clean without any brushing or harsh chemicals. It’s gentle, effective, and great for hard-to-reach spots.

Ultrasonic frequency explained (42,000 Hz)

The Magnasonic CD2800 runs at 42,000 Hz. That means it creates 42,000 sound wave pulses every second. This level is strong enough to clean deeply, but gentle enough to avoid damage to delicate items like gold jewelry or glasses.

Higher frequencies are used in lab-grade cleaners, but 42,000 Hz is perfect for home use—fast, safe, and effective.

Ultrasonic vs traditional cleaning

Traditional cleaning methods like scrubbing or soaking may clean the surface but can miss tiny corners and may even scratch soft materials. Ultrasonic cleaning uses bubbles to do the work, reaching every small gap and crevice.

Here’s how it compares:

Cleaning Method	How It Works	Pros	Cons
Manual Scrubbing	Brush or cloth with cleaner	Easy and cheap	Can scratch items; hard to reach all spots
Liquid Soaking	Dipping in cleaning solution	No tools needed	Doesn’t fully clean small spaces
Ultrasonic Cleaning	Sound waves and bubbles in water	Deep, safe, no chemicals needed	Needs a machine

Key Features of the Magnasonic CD2800

3-minute automatic cycle

The CD2800 starts with one button and runs for 3 minutes. After that, it shuts off on its own. There’s no timer to set or buttons to hold. This makes it quick and easy for regular use.

Water-only or solution-compatible

You can use just regular water for most cleanings. For greasy or very dirty items, you can add a drop of dish soap or a cleaning solution made for jewelry. It’s safe either way.

Safe for delicate items

This cleaner is safe for:

• Gold and silver
• Stainless steel
• Glasses and plastic lenses (non-coated)
• Retainers, dentures, and mouth guards
• Coins and small metal tools

Avoid using it with pearls, opals, or soft stones, which may be damaged by ultrasonic waves.

Small and easy to store

The CD2800 is light and compact. It fits well on small counters, in drawers, or in cabinets. You can leave it out for daily use or store it away easily. It’s great for apartments, dorms, or anyone with limited space.

What Can You Clean with the Magnasonic Ultrasonic Cleaner?

The Magnasonic Professional Ultrasonic Jewelry Cleaner isn’t just for jewelry. This compact machine works wonders on many small items that are hard to clean by hand. Using only tap water and ultrasonic waves, it gently removes dirt, oils, and residue from deep, hard-to-reach areas.

Jewelry

You can safely clean gold, silver, platinum, and diamond jewelry. It’s perfect for rings, earrings, chains, and bracelets. The ultrasonic waves lift grime from small crevices that toothbrushes can’t reach—especially around stone settings and clasps.

⚠️ Avoid using it for soft or porous gemstones like opals, emeralds, and pearls. These stones may crack or dull in ultrasonic vibration.

Eyeglasses and Sunglasses

If your glasses have metal or hard plastic frames, you’ll love the result. It clears smudges, dust, and oils from lenses and hinges without using harsh chemicals. Just be sure to check that your glasses don’t have coatings that are sensitive to vibration.

Dental Items

You can clean retainers, dentures, Invisalign trays, and mouthguards in this machine. It reaches into grooves and tight spots, removing plaque and buildup safely. Always rinse with water after cleaning to remove any loosened debris.

Watch Bands, Coins, and Small Tools

Watch bands (metal), collectible coins, tweezers, and even precision screwdrivers can all be cleaned effectively. Just remove the watch face before cleaning the band. For coin collectors, the cleaner helps restore shine without using abrasives.

Razor Heads, Keys, and Small Hardware

This cleaner is ideal for shaving razor heads, keys, nuts, bolts, and other everyday tools. These items collect grime and oil over time, and ultrasonic cleaning makes them look new again.

Item Type	Can It Be Cleaned?	Notes
Gold & Diamond Rings	✅ Yes	Avoid soft stones like opals or pearls
Eyeglasses	✅ Yes	Avoid coated lenses sensitive to vibration
Retainers/Dentures	✅ Yes	Rinse after cleaning
Watch Bands	✅ Yes	Remove the face before cleaning
