CREWORKS Ultrasonic Cleaner with Heater and Timer, 60W 2L Stainless Steel Jewelry Cleaner 5.9"x5.3"x4" Tank Sonic Cavitation Machine for Cleaning Watch Glasses Retainer Denture Parts

I have been using my ultrasonic cleaner for just over one year now and it still works like new. I use it to clean my glasses, watch, leatherman, pocket knife, keys. Basically anything I regularly have on my person. Its a little gross just how much comes off of everything when I do my bi weekly cleanings. Everything comes out looking amazing and the effort is so minimal. I simply fill it with warm water, add in some Dawn dish soap, and drop in an item. The act of running the machine generates enough heat for cleaning most of my items so the heater is usually not needed. Cleaning is just pouring out the water and rinsing the basin and basket with warm water and then letting it dry.One cool thing I found for rapid drying things like my glasses and leatherman is using an "SDFM Electric Air Duster" which blasts them with air and blows out the water in seconds.

Perfect. Takes a LONG time to heat-up, but it holds the heat just fine, so it's ok. No complaints other than that.

We are using this for cleaning Musical Instrument parts such as Silver Plated Brass Mouthpieces, Plastic & Hard Rubber Woodwind Mouthpieces, Silver Plated and/or Lacquer coated Brass Musical Instrument parts. The unit arrived quickly and was packed adequately. Set-up was quick and easy. We added a brass fitting to the drain to attach a clear vinyl drain hose since this unit is being used on a counter top. This is our findings after using it for a month about a few hours each day.The settings for the temperature are in Celsius so many will have to convert temperature accordingly. It does take a lot of time (30+ minutes), to heat up the solution (40 C), so plan accordingly if your cleaning requires heat. Conversely, if you are doing several batches of cleaning, be careful about the unit going over the set temperature, (according to the read out on the panel). We've turned it off in between uses to avoid burning out the heating element.The capacity is about 2-1/2 gallons but depending on the volume of the items you are cleaning, you don't need to fill it completely. A benefit I didn't realize with the shape of the tank is when a cleaning cycle is finished, you can pull the basket up and turn it 90 degrees and place it on the ledge to allow all the cleaning fluid to drain out before rinsing off the items.The cleaning power of this unit seems to be adequate for general use. Longer or repeated cleaning periods may be necessary for some items. It is dependent upon the severity of the items to be cleaned and what solution you use. We are going after calcified deposits inside brass tubes and have experimented with a few different solutions. So far, our best results have been with a mix of White Vinegar, Baking Soda and Sea Salt. Another good cleaning solution is a dilution of Simple Green HD and Dawn Ultra Dish Detergent. Both of these have worked well being heated between 35-45 degrees Celsius at 10-15 cleaning times.While some reviews complained about the noise level, being that this is used in a shop area, we did not find it overly loud. With the lid on, the sound was slightly lower and it helps retain the heat inside to aid in the cleaning. You will not be able to have a conversation on a phone near it as the Ultrasonic waves cancels out most microphones but standing and few feet away will solve this.Draining the unit and changing fluid. As previously mentioned, we added a brass hose fitting and a large clear vinyl tube to drain into a 3 gallon bucket. The unit will have to be tilted towards the drain to remove all the fluid. A towel to wipe down the tank clean and an occasional use of a Stainless Steel Cleaner / Polish like Sprayway helps keep everything neat and water spot free. (We have HARD Water)Lastly, the issue about the power switch on the backside of the unit. It is a minor inconvenience but somewhat of a safety as well. It forces you to keep the immediate area around the unit clear, which helps with the airflow ventilation around the unit. (It does get warm). Also, if you spill fluid while removing the basket or items you are cleaning, you are less likely to spill on the backside since you are pulling items towards you in the front.General Impression is that we are pleased with the unit and hope that it will last for a while. For the size of the unit, it will clean most items well but could use more powerful transducers to create stronger cavitation bubbles and heat up quicker. For the price, it is hard to beat and should serve the average user well.

I hate to leave a bad review, but I want to save other people some money. When this machine works, it's a fine unit. But the internal electronics are not up to the task. The machine goes through fuses like crazy. I had problems with my first unit and corresponded with the company, as well as bought a large supply of spare fuses. The company was nice enough to send a replacement, and I appreciate that. But the second unit is no better. Last night I got the unit out of hibernation and was able to run one cycle of the machine to do the first step in cleaning a bicycle chain. It worked fine for the first chemical. But since then, I have gone through a dozen fuses and it just won't work. Now I have a half-cleaned bicycle chain, a dead unit, and an empty box of fuses. I'll be looking for a much better-quality unit to replace this one.

I have always deep cleaned my guns the hard way, which was complete disassembly, lots of scrubbing with a toothbrush, and some good degreaser. The problem with that is you always spot some grime you missed in the nooks and crannies. I bought this product hoping it would relieve me of some work. I wasnt disappointed in the least. My test gun is a Smith & Wesson M&P Shield 9mm that hasnt been cleaned for years. I mean allot of years. I got it cheap, and knew it was going to be nasty inside due to the lack of maintenance, and the guy carried it in a very dusty environment. I used Zep citrus degreaser ( bought on amazon) with this machine, and about a 6:1 water to degreaser ratio. I ran each batch of parts for 10 minutes in the solution I had mixed and heated. I used plastic 30ml medicine cups with a nickel in the bottom of each to hold the small parts like pins, and springs. The results are amazing. All the parts were spotless. For those of you who dont know, the M&P Shield has a sear disconnect lever that is painted yellow. This machine took of 100% of that paint off, now the part is just shiny chrome. It did NOT remove some exterior rust on the barrel near the muzzle, but I wasnt using the correct solvent for that, so I wasnt expecting it to do so. Also its worth noting that the unit came with a small clamshell basket of the type commonly used in dishwashers. It works great for small parts, and is a really thoughtful freebie. Overall I am very pleased. Though the machine is not silent, my cussing was kept to a minimum due to the easy way this thing works, so overall it was quieter. My dogs were right next to it and didnt even notice it, but they did notice I was eating a sandwich, well, WE were eating a sandwich. If you purchase used firearms, and even some new ones of Turkish origin, this thing will save you much work. Thanks for a great product!
