Magnasonic Professional Ultrasonic Jewelry Cleaner with Digital Timer for Eyeglasses, Rings, Coins (MGUC500)

Love how easy and that you can see the actual dirt leaving the jewelry!

I bought this to clean my rings and earrings. Everything now looks brand new like when I bought them. Wanted other people to know how well it works.

The vibrations scares my cat, but it does the job in a few minutes.

I have used industrial ultrasonic cleaners for a couple of decades when I worked in R&D labs, but never had a home unit. Browsed these units on Amazon and selected this one due to the good reviews. It came today and I gave it a real challenge. I had a felt tip marker that uses fountain pen ink that had dried up a year or two ago and had not been cleaned out until last weekend. The ink (Noodlers Kung Te-Cheng) was like blue tar and it took many rinsings and soakings in pen flush and warm water to remove it from the open barrel. The grip section has numerous fins inside that control the ink flow to the replaceable felt tip. No way to flush this out, but I had soaked it in pen flush for some days, and even a bleach solution to no effect. Since the grip is clear I could see what was happening to it in the Magnasonic. Put a cup of warm water with a squirt of ammonia and Dawn detergent into the bath and in went the pen section. Wow! a cloud of ink came out big time. A couple of minutes the 8oz water was deep blue. Replaced the cleaning solution and the pen section was cleaner. Repeated two or three times and finally I got all the ink out of the section. Could never have gotten all the ink out without an ultrasonic cleaner. Then, just to see, I dropped the replaceable felt tip into the solution. This consists of a plastic holder that fits snugly into the grip, a tiny felt bullet tip and a 1 inch long tiny tube (1/16 inch diameter). It was filled with dried ink. Well, the tiny tip floated in the solution and blue ink boiled out of both ends. A few minutes and it was completely cleaned of ink! So in went a fountain pen nib/feed/grip section that had been well cleaned out with pen flush using an ear syringe until no more ink residue came out. But, in the Magnasonic a gray cloud erupted from both ends of the section and continued for a couple of minutes and stopped. Now this pen section was cleaned to normal standards, but the Magnasonic removed all the minute residue from the nib and feed which would have been important if I had wanted to use a lighter color ink in it. Then I cleaned a gold ring with a sardonyx intaglio cut stone. The back of the ring under the stone is open and collects body oils. Immediately a cloud came out of the ring and in a minute it was clean. In went a pair of eyeglasses (Dawn detergent only, no ammonia just to be on the safe side). A cloud came out from the nose pieces. In a minute I rinsed them off and wiped them with a clean microfiber cloth. Beautifully cleaned. I am amazed at how well this machine cleans. I got the Blitz cleaner but have not used it, saving it for jewelry. Remember, this machine WILL NOT POLISH OR REMOVE TARNISH. But it cleans off dirt, oil grease, and residue wonderfully well, getting deep into micro crevices. The instructions say to start with water, but water will only remove loose stuff. Several drops of dishwasher detergent will remove all kinds of gunk. I am glad I got this Magnasonic Ultrasonic Cleaner. I wish the lid came off as I like to watch the cleaning action and you only need it on to keep the chamber clean. I rinsed and dried it before I put the machine away. Easy to use, one button starts, one button stops, one lets you cycle through 180, 280, 380, 480, and 90 second cleaning cycles. The stop button lets you stop and restart the cycle you were using. When unplugged it will reset to 180 seconds the next time it is plugged in. Nice basket and a watch band fixture to clean WATER PROOF watches (not water resistant). I also cleaned my small Victorinox Swiss Army knife in it to get the pocket lint, etc. out.

I use this multiple times but it seems like the first item I put in it was a much stronger vibration and I could actually see the water vibrating. After I did a few more items to test out how dirty my jewelry was, it seemed to not be as effective. I did end up purchasing jewelry cleaner instead of just having the unit clean in water and it seemed to work okay but just not very strong

I ran this ring through the machine three times, but that didn’t really do much to remove the dirt. I took the ring out of the machine and then scrubbed it with jewelry cleanser. Then I put it back in the machine and this is what came out. So beautiful! The instructions say you can use a soap and water to clean the jewelry if you don’t have cleanser.

Nice product, but this is my second one. The first one lasted only about a year. I would have thought it would last better, as I had a different cleaner for years. Will be sure and check this one to be sure it last better. But I do like it. Thank you.

I like the fact I can clean my jewelry with tap water and dish soap and not having to use chemical. There is hardly any noise and very easy to use.

I love this machine. I have been wanting a jewelry clear that works well and is hands free no mess no fuss. This is perfect! With a little bit of jewelry solution cleaner and water, it makes you jewelry look like new again. You cant use it for pours stones like pearls and opals but with inexpensive costume jewelry, I use it on. Havent had a problem but my real stuff of those do not get put into it. Definitely a good buy!

I bought this April 1, 2022. It just died today, April 17, 2023. A little over a year of service at weekly intervals. With the right compound, it does a fantastic job of clearing the crud and dead skin cells out of my watches. It died after a year, but for the price, who cares? Ill buy another one and consider them disposable.
