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

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 purchased this for my mothers Christmas gift. I had experience using the industrial versions and can say this works 90% as well. The first item I tested was on my moms metal watch band. I had to hold the watch itself (submerging the watch can damage it or break the water tight seal). The water began to turn grey then black removing all of the oils it had collected from her skin (quite disgustingly awesome to watch). I needed to eventually replace the water with clean water and run it through again. All that was needed is a bit of dishwashing liquid and water. I prefer heating some water in the microwave (add a bit of rubbing alcohol if you like as well to help cut the oils). Remember afterwards to clean the unit. Over time it will collect salt from the water where the metal pan meets the housing. I found the lid is really just there to cut down the noise. I preferred leaving it open as it would be one less thing to clean or collect residue. Next I dropped in a few rings and necklaces (silver and gold). It worked like a charm!! Simply rinse and wipe afterwards. I suggest using a toothbrush for stubborn areas such as intricate rings or areas where there is excessive buildup of grime. Avoid using on pearls. Be aware that jewelry with stone/diamond settings should be secure as this could cause them to loosen and fall out. So you want to check to make sure the jewels are still attached before dumping the water down your sink. This is not for fake/laminated/painted costume jewelry as it will make the coating come off. I used it on some glasses. You will be amazed how much grime they collect (about as much as the watch band). We use these in the optical business. They will not harm your lens coating. Your nose bad will become much cleaner as well…but if they are too green then have them replaced at an optical shop. I can tell you from experience that with glossy plastic frames that it can peel the glossy coating leaving places with a matte finish. There was one especially bad silver rope. It was more tarnished than dirty. Sure, this cleaned it. Just be aware that it isn’t designed to remove tarnish (you will need to polish tarnish by hand with a special cleaner & cloth after cleaning with this machine to remove tarnish). So needless to say the silver rope became clean but was still essentially black afterwards (yes it was genuine silver). I personally find it a joy watching items that you think couldn’t possibly be that full of grime create this cloud of nastiness. It makes me want to add fresh warm water and dawn and find what else to clean. My cell phone case? Sure! My grandpa’s nasty Case pocket knife? No problem!! Word of warning (again from experience)…it’s not going to harm you putting your fingers inside briefly. But don’t do for long to feel the tickle. It will pull out all of the natural oils from your skin causing extreme dryness and will make your nails brittle & crack. It can even rupture the capillaries in your finger tips making them red and bruised. *The unit is much smaller then appears in the photo. The opening is about the length of a pair of eyeglasses*

Love this thing, it gets all the funk out of my jewelry m. I even use it with glasses

Its really hard to write a review on a product after having it for such a short amount of time. It works as described. I thought it would be more powerful. It can take multiple cleanings to get all the grime off sometimes. Otherwise, it works. Id prefer to write product reviews after having the item for a few months as opposed to only a couple of weeks.

Had one before and lasted almost 12 years and I use it every day

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!

Cleans glasses ,mouth guard, and diamond rjng sparkles !!

This machine cleaned my jewelry well with no damage to my precious stones. You can see it working and it operates fairly quietly. Would recommend!

I bought this specifically to clean my invisalign aligners and it works great. Super easy to use and rinse out. Highly recommended.

It wont do a thing for tarnish, but fantastic for shaking the normal everyday dirt, oils and grime out of your jewelry, watches and glasses.
