DK SONIC Touch Ultrasonic Cleaner with Heater,Timer,Multiple Cleaning Mode for Carburetor,Automotive Parts,Gun Parts,Circuit Board, Industrial Commercial Ultrasound Cleaning Machine (4L, 110V)

We own a small engine repair shop and purchased the 15L for carburetors and other parts. This unit works so well, we plan on purchasing a smaller one for 2cycle carbs and smaller jobs. The unit is relatively quiet, and the large touch is very easy to control. It heats very well, and is quite insulated. After shutting the unit off, the water is still in the 90’s the next day! (as long as you put the lid on.). The temperature is accurate, and within 1 degree. (Checked and monitored with our Fluke thermometer.) Once the temperature is reached, the heater shuts off and turns back on as necessary to keep it at the desired setting. We found that the water usually only gets hotter as you run the unit from the heat of the electronics or perhaps the ultrasonic effects? But usually increases a degree or two. It has a cooling fan in the bottom as the electronics do generate some heat. We have put several carburetors through the unit so far, and we are impressed! The pictured carburetor is off of a snowblower and hadn’t been used in several seasons. After a 30 minute cycle of full wave, and an additional 10 minute on sweep, with water temperature at 150C, the results are impressive! Whats even more impressive? We have been using just water! We did try another carb with some dawn dish soap to experiment, but results have been remarkable. As another experiment, we took some air filters from Husqvarna chainsaws and put them through the half wave cycle. After just 5 minutes those things came out looking like new! We have also done a couple spark arrestor screens, and even tried a fowled spark plug. It actually done really well. As for the longevity of this unit, time will tell. But it does seem built quite well, and comes packaged very well also. So far we are impressed, and the unit is paying for itself.

This little guy is pretty impressive. I like that you can heat the tank before starting the cleaning cycle, it really makes a difference in cleaning effectiveness. Three different cleaning modes seem to tear through dirt and buildup. I primarily use it to clean firearms and parts, it does a great job of unlocking carbon locked parts, breaking up deposits on suppressors, etc. Some scrubbing/scrapping is still required after cleaning cycle, but for the most part, it does a great job.This particular model does not have a drain. I can definitely see how that would make things easier when it comes to emptying the tank to switch between solutions and avoid potential water damage to the unit while doing so. It’s not quiet. It’s also not horrific. It does make my hearing aid freak out though.Overall, I’d probably go up a model to get the drain, but I would recommend this brand.

Love this little device. I am a cosmetic chemist, which requires me to make a number of plant-based extracts. This is a wonderful tool for disrupting cell membranes, getting the last drop of goodness from extractions. Make sure to use good glassware, as I had a lesser beaker, get cracked in the process. Best to stick with the heavy-duty Pyrex stuff.

The only downside I found for this unit is the extremely small font used in the included "manual"/information sheet making it almost entirely unreadable. Plus I was not able to find recommended minimum/maximum water levels marked on the tank. I downloaded the online general manual for all of these units and found this statement under Safety Precautions: "DO NOT operate the unit without fluid in the tank. Always ensure that the fluid is no higher than the max mark and no lower than the minimum depth of 7cm."My first use of this device for baffle cleaning was fairly successful. Overall, I have been manually scrubbing the removable baffles using CLR (works better than Simple Green) taking quite some time and aggravation to get them very clean.The suppressor (with removable baffles) to be cleaned had 400+ rounds of .22LR, 300BLK subs and 300BLK supers through it and was dirty and carbon fouled.I purchased this unit to hopefully make the cleaning process much easier- and it did do that. I performed an initial cleaning test with two baffles each using a plastic baggie 1/3-full of a soapy water mixture, then 100% Simple Green and finally CLR.CLR has proven to work better for manual carbon cleaning. Using this ultrasonic unit for an initial test of 15 min. each with water temperature at room temperature and using Power Sweep mode- CLR was still a better cleaning option of these three materials.Finally I placed all eight baffles into a 1-quart Zip Lock baggie- 1/2 filled with CLR and placed into the ultrasonic's basket sitting in water filled 3/4 of the way to the top of the tank. After 60 minutes runtime (maximum OEM recommended time) I removed all baffles and scrubbed the remaining carbon from the baffles using a bronze bristled brush. The carbon that was left after the ultrasonic completed its 60 minute cycle was fairly easy to remove, as it has been softened greatly.Next time I might try a 60 minute cycle and then a 30-minute cycle, which I suspect would work even better. I did not find this 4L ultrasonic unit to be very loud with the lid in place or removed while in use in my workshop building, unlike what someone else mentioned in the reviews.
