Please note that one chip in the ultrasonic cleaner took me about 8 minutes. 4 minutes on each side. But that doesn’t mean you can pile 20 or 100 chips in there and get the same results in the same amount of time. I just tried 14 chips and it took around 20 minutes.(The chips lay flat and I flip and rotate them every 5 minutes)
Even after the 20 minutes they weren’t 100% clean. They looked bright and clean but some still had little yellow spots. So I will continue to test for a better cleaning solution or maybe a different method (For cleaning power I have never liked using dawn in ultrasonics)
