This isn't a high-end professional ultrasonic cleaner, but it's way more affordable and "good enough" for most uses outside of a lab. I bought it to clean flux residue off circuit boards and my first attempt went extremely well.I used about 350mL of Chemtronics Flux-Off with 1 gallon of distilled water. The specs for Flux-Off recommends running at 60degC, but the water only got up to 45degC at the end of a 30 minute cycle. I likely could have let it run for an hour first to let it warm up fully and de-gas the solution, but I was anxious to try it out. Despite running below spec, the PCB came out clean.The cleaner came with a drain hose and adapter, but I need a smaller hose to fit through the opening in a 5 gallon jug that I got from ULINE. I ended up getting a brass 3/8" thread to 3/8" barb adapter and a 1/2" hose. At the end of the cycle, I just opened the valve and everything drained into the waste jug. Very convenient!I really should have used deionized water instead of just distilled. The distilled water left a few water spots, which DI is less likely to do. I'm planning to get a 4-stage RO/DI filtration system to make my own DI water instead of buying it online.Overall, I'm very happy with this. As long as you don't expect a industrial-grade piece of equipment, I think you'll be happy too.
