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

The product is easy to use with multiple timer options and automatically shuts off when time is up. The only additional feature that would be nice is to be able to unplug the power cord from the unit. Just a minor inconvenience.

Didn’t know I would appreciate this cleaner so much. It’s great size to get multiple pieces done at once. Happy with this purchase

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.

The Magnasonic Professional Ultrasonic Jewelry Cleaner does an awesome job of making your jewelry sparkling clean. Rings, watches, chains, all look brand new. It is hard to believe all of the gunk that came off of our jewelry. It also does a great job of cleaning sunglasses. If you shave with a DE razor, it will clean and restore it to NEW condition.

This is the 2nd ultrasoninc cleaner Ive purchased since opening my jewelry store on Etsy but the first one lasted twice as long. This one did work great (and I have to say, I used it a LOT) but last week the motor literally melted into oblivion and I had to toss the whole thing. If you are planning to clean with it more than a couple of times a week, I recommend either getting a high quality (AKA pricier) one that is guaranteed to last, or inexpensive smaller ones you plan to replace more often. Extended or frequent use of this particular machine burned the motor up - but luckily didnt damage anything or start a fire.

Gets the job done cleaning the frame You might want to use other methods to clean the lenses

This machine is easy to use and works great!!! I used 1 part ammonia and 2 parts water. Everything came out super shiny.
