Cleaning Copper Oxide Off a Water Block: Ultra Sonic vs. Vinegar

We're cleaning off a GPU water block that seems to have copper oxide on it. In the process of trying to use our ultrasonic, we may have also added some patina to the coat, but we did ultimately get it clean. Just playing around with different cleaning solutions to see what happens! This would also be useful for cleaning CPU blocks, GPU blocks, etc., but we're not posting this as a tutorial -- more of a chronicle of our adventures in trying to clean the block.
