Do ultrasonic cleaners really work? I always wanted to time lapse this, I put a really small engine part in one of my ultrasonic cleaners to see if it actually cleans with just water alone as I have always been skeptical. But as you can see it works pretty well I'm pretty sure they vary by brand though. #ultrasonic #cleaner #make #engineering #science #technology #mechanics #maker #cleaning #hacks #tips | Warped
