Top Customer Reviews
This cleaner has five pre-timed settings, which I have to admit are handy, but this ultrasonic's cleaning power is what has really impressed me and my family. We've used it for different things, but jewelry is where it really `shines' - pardon the pun! This ultrasonic removes hairspray, oils from lotion, fingerprints, etc., leaving our jewelry shining like new. Unlike a "sonic" cleaner, which uses vibrations only, we've trusted this ultrasonic on some of our more delicate items; a pair of antique eyeglasses (gently but thoroughly cleaned them), an antique magnifying glass with filigree and delicate handle (two cycles, one to clean the glass and filigree end, then turned the magnifier around to clean the handle with another cycle, leaving the lid open both times).
There are 5 automatic settings - push the Set button for the pre-timed setting you desire, press On and let the cleaner to do its job - a function that's both helpful and practical. Auto settings are displayed in seconds, but the minute times are 1 ½, 3, a little over 4 ½, a little over 6 minutes, and 8 minutes (we timed the settings, the cleaner ran accurately).
I've been using hot water with a good squirt of dish liquid, mixed well before using. Just pull out the plastic basket afterward and rinse everything under the tap (we do make sure the drain is closed). Always check with your jeweler or one of many online sites to see what stones/metals may be safely cleaned in an ultrasonic cleaner.
1) Very powerful cleaning ability yet quiet operation
2) Able to safely clean antique items (use the shortest cycle and check for any loose areas prior to cleaning), unlike `sonic only' cleaners which may damage items
3) 5 useful Auto Timed settings
4) Cleans glasses and even larger items when the lid is left open
5) Operating buttons located on the unit, not the lid - durable design
6) 6 month warranty
1) Does not heat water, which would be useful
The New Trent CD-3800 is a well designed powerful ultrasonic cleaner with the extra feature of pre-timed settings - I'm impressed with this ultrasonic cleaner.
This unit comes with a white plastic basket to place your items in. The basket has a round area in the center with smaller holes to place tiny earrings and other very small objects so they won't fall through when you lift it out. It also comes with an arch shaped piece for inserting post earrings and holding waterproof watches. I also use this piece to hang slender chains so they won't tangle when cleaning several items at once.
I use a jeweler's loop to check jewelry prior to and after cleaning, and despite being very quiet it is quite powerful and does a great job removing grime and leaving jewelry sparkling. I usually run the unit 2-3 times as recommended for jewelry and once for glasses. I can fit 2 pair of reading glasses into this unit. I have cleaned jewelry, eyeglasses, sunglasses, coins, CD's, an electric shaver head, razors, and small porcelain statues - all with wonderful results.
I would recommend using Dawn or Palmolive dish liquid mixed with warm water for best cleaning results, and always check to make sure items are safe to be cleaned in an ultrasonic cleaner. If cleaning only diamonds and/or gold, mix a bit of ammonia into warm water with your dish liquid - this is what my jeweler uses and suggests.
Place a dry cloth against the side as you empty any cleaner - this prevents water from dripping down and seeping into the circuit board.
I've been very pleased with the results of this model, and recommend this unit not only for jewelry, but cleaning many other items as well.
UPDATE: 10 months of regular use and still working very well. I noted some people are having problems cleaning certain items. A sonic cleaner, unless it is a truly professional model - that which a jeweler would use, cannot remove long-term built-up dirt or scum. This would require manual cleaning with a soft brush or cloth first (if item is not too delicate) or a professional cleaning by a jeweler. While labeled as a professional unit, this is an affordable home model.
I would stress again, please check an online listing for stones and settings that are safe to use in a sonic cleaner, or ask your jeweler.
After rinsing in a tightly closed sink you can place your jewelry on white tissue paper (the type gifts are wrapped in) to dry - it is very lint free. You can also use a flat piece, not crumpled, to dry the top of your stones, preventing water droplet marks.
Also, please do not put your fingers in any sonic cleaner while running.
I continue to find this sonic cleaner perfect for maintenance cleaning.
Addendum 2-2-12: My review is based on the model CD-2800 (see review above). The cleaner advertised as of 2/2012 is model CD7810 as stated in the Product Description (I just noticed this). The cleaner also looks quite different. I cannot comment on this model as I did not purchase it. I do not know why my review is with this model.
