Ultrasonic Cleaning Brass & Copper With Citric Acid | Crest Ultrasonics Test

Today I’m testing how well a Crest P1100HT ultrasonic cleaner can clean a brass and copper union. Surprisingly, the cleaner removed a significant amount of oxidation from both the brass and copper using a citric acid solution. I’m going to keep experimenting with the mixture to find the best concentration and cleaning process. Once I figure out a recipe that gives me consistent results, I’ll make another video showing the exact mixture and process. Hope you enjoyed the video, and stay tuned for the next test!
