  • Only 2.2 lbs / 1 kg
  • HxWxD: 5.4 x 8.2 x 5.8 inches / 137.2 x 208.3 x 147.3 mm

MGUC500 is top member of the ultrasonic cleaners for home use.

With this model, you can clean:

  • Jewelry: Necklaces, Bracelets, Rings, Earrings, etc.

Magnasonic MGUC500 only needs tap water to clean your jewelry and other items.

But for dirty pieces, you can add 5-10 ml of mild dish soap or use commercial solution concentrates.

MGUC500 gets the job done thanks to its 42,000 Hz ultrasonic waves.

These high frequency waves creates oscillations and bubbles which loosen dirt and oil stuck on your jewelry.

Some devices might be difficult to use but not this one!

Using MGUC500 is very easy: you can control the cleaning session with the 5 presets.

The digital timer has programmed sessions of 90, 180, 280, 380, 480 seconds.

All you have to do is choose one and start the cleaner.

Attention:

  • Glasses/Sunglasses with scratches or cracks
  • Antique jewelry
  • Jewelry with loose stones
  • Jewelry with soft/porous stones like pearls, emeralds, amber and opal
  • Tarnished silver/sterling silver

In doubt, don’t refrain from consulting your local jeweler. Always act with certainty.

    • Only 2.25 lbs / 1 kg
    • HxWxD: 4.9 x 4.1 x 4.1 inches / 124.5 x 104.1 x 104.1 mm
    • Easy To Use

The UC21 is the compact member of the Magnasonic jewelry cleaners.

With this model, you can clean a wide variety of items:

  • Hygiene Items – electric shaver heads, toothbrushes, dentures, razor blades
  • Jewelry – necklaces, bracelets, rings, earrings, body jewelry
  • Watches – waterproof watches, watchbands
  • Stationary – pen-heads, seals, rubber stamps
  • Silver items that have tarnish (see special instructions on page 7 of the manual)
  • Other Items – tools, watch parts, coins, key-chains, valves, machine nozzles, badges, instruments, filters, and kitchen utensils

It has a tank volume of 220 ml.

Thus it offers enough space for your eyeglasses, mouth guards, jewelry, shaver heads and other items.

You can easily fill this tank with tap water and you are set to go.

UC21 produces ultrasonic waves of 36-40 kHz.

Although, its frequencies are lower than the previous two models, they are enough to create oscillations and a gazillion of bubbles which will loosen oil and dirt from your pieces.

The UC21 has only one cleaning cycle of 5 minutes.

All you’ll have to do is press a button and come back after 5 minutes to get your pieces clean and shiny.

Note that this model does not come with a jewelry tray.

Unfortunately, you’ll have to buy it separately.

It has a cable length of 61 inches.

Pros Cons
  • Ideal size for mouth guards, dentures, eyeglasses and watches
  • Automatically closes after cleaning session ends
  • No digital timer
  • Not suitable for soft-porous stones like coral, pearl etc
  • Not good for scratched or cracked items

The verdict: Is it MGUC500 or UC21?

MGUC500 is the most talented ultrasonic cleaner and it clearly leads the pack.

It offers a large tank: very good for cleaning many items.

It also produces higher frequency waves than the UC21.

MGUC500 also has a digital timer with 5 presets which always comes in handy.

When we add up all these advantages, we can’t really see any good reason to choose the CD2800.

Because, it lacks the digital timer and presets.

But there might be a case where you’d like to pick the small UC21 ultrasonic cleaner.

If you are looking for a ultrasonic cleaner mainly for dentures, pen heads and watch bands, then UC21 can be chosen over MGUC500.

So, if you aim to clean lots jewelry pieces MGUC500 is your winner.

But if you want to clean eyeglasses, mouth pieces and other non-jewelry pieces, and only clean occasionally few jewelry pieces, then UC21 might be a better choice with its smaller size.
