UltraSonic Clean is Easy
Handy device ... BIGGER than I thought, Rounded top, limited on shelving where it can be stored .... Works well ..... Ultrasonic, sound waves clean with water, or a drop of soap if you prefer .... Can use on more than just jewelry ..... Try on eyeglasses, trinkets, rusty tools, nail clippers, dentures, and moreBe careful on jewelry with prong settings, gems can fall out with overuse .... Occasional, on lowest timer still does a fine job for those .... Timer setting can be longer or shorter timing .... Think of it like a washing machine on 'delicate' cycleEarrings come out shiny, fresh looking .... Tend to sparkle more .... Nose rings lose the nasty dead skin thing, thereby being more healthy when cleaned frequently ... Necklaces rid of body soil .... Face it, we're human, we shed skin cells and gunk .... I like knowing I can wear clean jewelry, same as clean clothes .... A nice feelingHas a DeGasser for water .... Takes out the part that tarnishes your jewelry ... Not all Cleaners have this .... An extra that is included in this practical machineDimensions: 8 long x 6 deep x 6 inches tall to top of Bubble ..... Long Cord 53.5 inches , (4 foot and 5 1/2 inches) .... Comes with a plastic basket for smaller items, and a watch band holder ... Good Machine.

5.0 out of 5 stars 14 years later, my wedding rings look like new again!
Reviewed in the United States on September 26, 2017
I use ultrasonic cleaners at work to clean very small machine parts and also to degas solutions that I mix (I'm a Biochemist eye disease researcher) and have found them to be very effective at work so I thought why not try one at home for cleaning my jewelry etc! I've been married for 14 years and have never gotten my wedding rings professionally cleaned. They were completely gross. It's pathetic that I let them get so bad, but there you have it. My engagement ring is a cathedral setting of the solitaire with 5 smaller diamonds set on either side. It's beautiful and I love it, but it gets dirty very easily because the solitaire is so exposed from every angle and because there are so many nooks and crannies where gunk can get stuck and hide. Anyway, here's what I love about this cleaner:

SIZE - This is a very compact unit and is really easy to store under a sink or in a cabinet because it has a very small footprint, but it has a large enough capacity to handle all sorts of jobs!

EASY - This cannot be overstated. Just because I'm a scientist doesn't mean I like reading instructions and spending hours setting things up and figuring them out. If anything I have LESS patience for that than the average person. I had this up and running within 3 minutes of taking it out of the box for the first time! The interior baskets it comes with are also very helpful.The instructions are clear (in english) and very easy to follow! I really love things that are both effective and idiot-proof!

VERSATILE - I love that this can be used for so many different applications besides jewelry like for cleaning coins, dentures, electric shaver attachments, glass or ceramic objects,

SAFE - If you're worried about this thing damaging delicate jewelry (with the exception of pearls, jade or emeralds), rest at ease. It is completely safe and gentle. I've used ultrasonic cleaners to clean things MUCH more delicate and sensitive than jewelry at work.

FAST/QUIET - You could literally use this cleaner daily if you wanted. The times are measured in seconds! And it's very quiet during operation.

QUALITY - This cleaner is very well made using quality materials. Nothing about it feels cheap to me and I think it will last a long time!

IT WORKS - This is the most important part, right? I ended up putting 3 rings in for the longest cycle on my first try and they were VASTLY improved afterward! My tougher, nastier rings seemed to need another cycle so I ran them through again and they were even better! I could still see some gunk, but it looked like it had all come to the surface of the white gold or stainless steel (flower ring) and I got out a pin and was able to easily scrape away the gunk leaving them shiny and clean and looking like new! One of my pictures shows the tank after cleaning my rings and you can see all the gunk in the bottom that came out! Amazing.

I think my results would be even better with the addition of "detergent" as mentioned in the instructions. However, what isn't mentioned in the instructions is what kind of "detergent" to use. This word means different things in different places and settings. For example, "detergent" in biochemistry has a very different meaning for me than when I'm filling my role as home maker. What am I supposed to put in with my rings? Laundry detergent? Dish soap? Hand soap? Special solution specifically made for cleaning jewelry? How much do I add? I had no idea, and I was too afraid to put something in that would ruin it. A quick Google search afterward told me that I could use a little dish washing liquid, but it would really be nice if the instructions were more specific about running a detergent cycle. My only other complaint is that this unit does not allow you to adjust frequency, only time. 42,000 Hz is more than enough to get the job done safely, but I always like having the option to adjust frequencies. These minor quibbles are not worth deducting a star over though.

I'm a big fan so far! I can highly recommend this for all sorts of uses. Hope this helps.

Please see bottom of this review for photo description.

Ive been using this for a little while now, purchasing it initially for the upcoming season of working on the car, lawnmower ect. In the meantime, ive been using it around the house, on various things like my grandfathers old jewelery, tools, camping knives, basically anything that has crevices where you just cant get a brush in to clean properly. A big test for ultrasonic cleaners to ensure they are actually working is using tin foil, place it over a support and put it into the cleaner. After a few minutes it will start to perforate and essentially disintegrate. I included a photo below which verified its function.

It works like a charm, cleans everything I put in very thoroughly on two 480 second intervals. It functions just as id hope it would, removing stuff that you cant see or cant access, I think the worst thing was an old nail clipper I cleaned that looked super grungy before from dust and rust, but now it almost looks like a new one. I wish that it were a bit bigger so i could fit more things in it to be honest. The bin is roughly 6 inches wide, about 4 inches deep and 3 or 4 inches tall.... Big enough for the small stuff but not big enough for a carburetor from a car. None the less, it works great and I have been very happy with it.

I found it works well with both degreaser, usually a half cup of spray nine in with the rest water for heavy duty stuff or a few drops of dish soap for light duty. You need to be sure to degas the water before use, it removes any bubbles which will otherwise absorb the ultrasonic waves... It works 10x better after degassing. I also find that it works best without the included white plastic basket, but you may decide to use it.

Anyhow, I wholly recommend this cleaner. i am extremely happy with it, its been very reliable and functions well. I will update this review if I have any problems with it.

For normal use for glasses, small item or items with aged dirt, it works pretty good for cleaning, but if items that with aged dirt or hard dirt, can't clean if not use cleaner with it.
