\"CD<\/div>\n

Let me start out by saying that this review <\/strong>is for a true ultrasonic cleaner, as opposed to a regular jewelry cleaner<\/strong>. There are big differences between the two. An ultrasonic cleaner cleans by ultrasonic sound waves<\/strong> that break up the dirt particles. A jewelry cleaner is nothing more than a vibrating compartment<\/strong> that tries to simulate the sound a sonic cleaner makes. Ultrasonic cleaners clean. Other cleaners try.<\/strong><\/p>\n

UPDATE:<\/h2>\n

\nThey do not sell this exact cleaner<\/strong> anymore. But most ultrasonic cleaners work the same and have the same functions. The concept is the same; sound waves break up the dirt particles<\/strong>. Now, on with the show…<\/p>\n

The box lists many features:<\/h2>\n

\n<\/p>\n

    \n
  • 3 minute auto shut off<\/li>\n
  • Stainless steel tank<\/li>\n
  • 600 ml – 1 pint capacity<\/li>\n
  • 42,000 hz of energy wave<\/li>\n
  • Cleans CD’s, VCD’s, and DVD’s<\/li>\n<\/ul>\n

    <\/strong><\/p>\n

    Sounds impressive…<\/h2>\n

    \nThe box goes on to say that you can “Use only plain tap water to clean<\/strong>“. Now I’m intrigued. Plain water?<\/strong> I’ve never heard of cleaning with just plain water.<\/p>\n

    \nThe box also says that you can clearly see dirt separate from the articles in just 3 minutes<\/strong>. It says it will make your rings, necklaces and earrings shine like new.<\/p>\n

    It cleans other things too:<\/h2>\n

    \n<\/p>\n

      \n
    • CD’s, VCD’s, DVD’s<\/li>\n
    • Dentures<\/li>\n
    • Glasses (people will love this)<\/li>\n
    • Razor blades<\/li>\n
    • Metal dishware<\/li>\n
    • Infantile articles (pacifiers, teething rings)<\/li>\n
    • Toothbrushes (?)<\/li>\n
    • Pen heads (calligraphy)<\/li>\n
    • Printer heads (why?)<\/li>\n
    • Small machined metal parts<\/li>\n
    • Ancient coins<\/li>\n<\/ul>\n

      <\/strong><\/p>\n

      \nOne of the things that I find odd is the fact that the box shows a cutaway section of the machine<\/strong>. It shows the lid, viewing window, stainless steel tank… But then it also shows you the gasket, transducer and motherboard. I’m so happy my ultrasonic cleaner has a motherboard.<\/strong> :)<\/p>\n

      \nHere is some basic info about the cleaner:<\/strong> It weighs 2 3\/4 lbs. Dimensions are 8″ L x 6 1\/2″ W x 51\/4″ D. The tank itself is over 5″ across. The Model# is CD-7800<\/strong>. And of course, it’s made in China<\/strong>. Isn’t everything? You can tell it’s made in China because of the broken English on the box and in the instruction booklet. It’s not a big deal though, you can still understand everything and follow the instructions easily.<\/p>\n

      Onto the review:<\/h2>\n

      \nInside the box you get a number of cool accessories<\/strong> along with the ultrasonic cleaner:<\/p>\n

      <\/p>\n

        \n
      • Plastic Basket<\/li>\n
      • Plastic watch stand<\/li>\n
      • Instruction booklet<\/li>\n
      • CD Rack for holding 1 or 2 CD’s at a time<\/li>\n<\/ul>\n

        <\/strong><\/p>\n

        \n\"Jewelry<\/p>\n

        \nAs soon as I opened the bag I was pleasantly surprised<\/strong> by the new car smell<\/strong>. You know that strong new smell of plastic and steel? I love that smell and the sonic cleaner didn’t let me down.<\/p>\n

        \n\"CD<\/p>\n

        \nSo now that it’s out of the box, first impressions are great<\/strong>. The cleaner is by far one of the coolest looking cleaners<\/strong> I have ever seen. Oval, domed, smooth, very streamlined<\/strong>. Something else I noticed, I don’t know if this is intentional or not, but it looks like the machine is smiling at you<\/strong>. Take a look to the left…<\/p>\n

        \nThis machine feels very well made<\/strong>. Really it does. It’s sturdy, durable and feels of quality workmanship. Plus, the stainless steel tank is killer.<\/strong> That highly polished steel tank glistens in the light and looks stunning. What eye-candy<\/strong>. It’s almost futuristic. I’m impressed with the overall look and feel.<\/p>\n

        \nThe really neat thing about that tank is the fact that it’s easy and painless to wipe clean<\/strong>. 2 seconds with a paper towel and the tank is spotless. That’s great.<\/p>\n

        \nSomething else that I notice is the power cord. It’s longer than most<\/strong>. This power cord is over 4 feet long. That makes using the cleaner much easier and safer… you don’t have to sit right next to an outlet. Well done.<\/strong><\/p>\n

        \nThe machine is simple enough to use that a monkey could do it<\/strong>. There are only 2 buttons: ON & OFF<\/strong>. And the Off really isn’t needed. The machine auto shuts off<\/strong> after 3 minutes.<\/p>\n

        So how does it work?<\/h2>\n

        \nEffortlessly!<\/strong><\/p>\n

        \nThe stainless steel tank has a water fill line<\/strong> (says max) that is easy to see on either side of the tank.<\/p>\n

        \n\"Jewelry<\/p>\n

        \nYou can’t get any easier than that.<\/strong> I filled a plastic bottle with hot water<\/strong> (not boiling) and poured it into the machine. Crazy as it sounds, I decided to do a cleaning with just plain tap water<\/strong> like the box says. I wanted to see if this claim was real.<\/p>\n

        I plugged the machine in and…. <\/h2>\n

        \n\"Ultrasonic<\/p>\n

        \nHow awesome.<\/strong> A blue light comes on. And not just any blue light but a neon blue<\/strong> that is out of this world. Really. It looks like a mini UFO<\/strong>. Very sharp and very unexpected. I loved that.<\/strong><\/p>\n

        \nI put my jewelry in the plastic basket and submerged it into the tank. Then I pushed the ON button. The red light came on<\/strong> and the machine started to clean and make this buzzing noise. Not a loud noise, but steady and constant<\/strong>. The instruction booklet calls it the “ZIZI<\/strong>” voice. That noise is the ultrasonic sound waves breaking up the dirt. You can actually see this by looking through the viewing window. Cool stuff.<\/p>\n

        \n\"Cleaning<\/p>\n

        3 minutes later…<\/h2>\n

        \n3 minutes go by, the machine shuts off and I lift the lid<\/strong>. Pulling out the basket I rinsed the jewelry off under tap water. Did my jewelry get clean?<\/strong> Sure! The gold was shiny. The diamonds were glistening. It cleaned pretty good. I was almost shocked<\/strong>. It cleaned in just plain water<\/strong>.<\/p>\n

        \nI tried another test. I put different jewelry in the basket and put it back in the tank. This time I added a squirt of dish soap<\/strong> to the mix. I turned it on. 3 minutes later, I pulled my jewelry out of the soapy bubbles and what did I find? I find this batch was even cleaner<\/strong>. Take a look for yourself. See all the dirt left in the bottom of the tank?<\/p>\n

        \n\"Dirty<\/p>\n

        \nI will definitely say that jewelry cleaning solution (or detergent) works better than just plain tap water (like there was ever any question<\/strong>).<\/p>\n

        \nThe instructions say for general cleaning, tap water is fine. But for enhanced cleaning<\/strong>, or extensive cleaning, detergent is necessary. That, and maybe an additional 3 minutes of sonic cleaning action. I wholeheartedly agree.<\/strong><\/p>\n

        \nIt’s like doing dishes in plain water, once you add in the soap it tends to get the dishes squeaky clean.<\/strong><\/p>\n

        Cleaning watches:<\/h2>\n

        \nNext up, I wanted to clean my watch<\/strong>. My watch is the dirtiest piece of jewelry I own because I wear it 18 hours a day. The links and hinges always get crud built up in the grooves. I was happy and excited that this cleaner came with a plastic holder for watches<\/strong>. <\/p>\n

        \nThis feature is what makes this sonic cleaner stand head and shoulders above the competition<\/strong>. I’ve never seen another sonic cleaner that cleans watches.<\/p>\n

        \nMy Watch fit into the plastic grooves just fine<\/strong>. I do suspect that you may have some problems if your watch doesn’t bend easily, has thicker links or a longer face. It may not fit properly. But, for standard watches, it works well<\/strong>.<\/p>\n

        \nI rinsed out the cleaner and put fresh water in. I didn’t want to use hot water around my watch because I didn’t want the face or movement to fog up which could make the parts rust<\/strong>.<\/p>\n

        \nWhen you’re setting your watch into the water, be careful that the watch itself stays above the water line<\/strong>. You don’t want to get that wet or submerge <\/strong>it. Water will quickly kill a watch and ruin the movement<\/strong>. If it’s waterproof, you should be fine (as long as the gasket doesn’t leak), but if your watch is water resistant, don’t get it wet.<\/p>\n

        \nI set my watch in the machine and quickly notice something I don’t like…<\/p>\n

        \nThe watch band dangled down and rested on the bottom of the stainless steel tank<\/strong>. I wasn’t happy about this. If your jewelry lays directly on the steel tank, it can scratch <\/strong>your jewelry.<\/p>\n

        \nSo what did I do? I improvised<\/strong>. I placed the plastic basket back in the tank first, then set my watch and holder on top of that. See picture below. Smart, eh?<\/strong><\/p>\n

        \n\"Cleaning<\/p>\n

        \nI shut the lid, pushed the button… I love that blue light<\/strong>… 3 minutes later I pulled my Watch out and looked at the band. It was clean. The dirt was gone. Even in the tight cracks of the band; Clean.<\/strong><\/p>\n

        \nSee the before (dirty) and after (clean) pictures of my watch below…<\/p>\n

        \n\"Dirty<\/p>\n

        \n\"Clean<\/p>\n

        But it doesn’t stop there…<\/strong><\/p>\n

        Cleaning CD’s:<\/h2>\n

        \nI keep my CD’s and DVD’s in mint condition<\/strong>. I’m pretty protective of them, so finding a CD to test that was dirty proved to be a problem. Mine are all clean<\/strong>.<\/p>\n

        \nI ended up going with an CD of Anita Baker<\/strong> from decades ago (The Songstress<\/strong>). It had a couple of smudges on it and some dust particles. Nothing big, but I needed something.<\/p>\n

        \nI put the CD on the stand (there is also a tube that is used to separate CD’s if you want to clean 2 CD’s at once<\/strong>). I dropped the CD and the holder into the tank and laughed<\/strong>. The CD rose up off the holder and floated on top of the water. Okay. That’s dumb.<\/strong> lol<\/p>\n

        \n\"CD<\/p>\n

        \nI removed the CD. Put the plastic tube on thinking that would weight the CD down<\/strong> and tried it again…<\/p>\n

        \nNOPE!<\/strong> The CD and the tube<\/strong> floated to the top. ha!<\/p>\n

        \nI don’t get it<\/strong>. You could achieve the same effect if you didn’t use the holder at all and just dropped your CD into the tank. (It makes me think it’s a gimmick…<\/strong>)<\/p>\n

        \nNo matter. I left the CD floating where it floated, closed the lid and hit the button. 3 minutes later I pulled the CD out and looked at it. Sure enough, it was clean. No smudges.<\/strong><\/p>\n

        \nDo note that you have to be careful when cleaning CD’s or DVD’s. The cleaner can erase the writing or text off the cover<\/strong>. The instructions recommend not <\/strong>to clean it more than twice. Plus, when you pull the wet CD out of the water, be careful when you dry it off, you don’t want to scratch the surface<\/strong> with a towel.<\/p>\n

        \nNeedless to say, I didn’t find the plastic holder very useful, but the CD did get clean<\/strong>, so I would say that it passed the test. No complaints there.<\/p>\n

        \nHere’s the breakdown of the PROS and CONS…<\/strong><\/p>\n

        PROS:<\/h2>\n
