Hello all, Time for a new video, this is one based on a post I saw on reddit. The post was about the commonly known 551 cleaning solution of 500mL of water, 50mL of hydrogen peroxide (H2O2), and 1oz (28g) of citric acid. It is primarily used to clean copper of oxidation, or the development of other salts. I myself have never thought that hydrogen peroxide would be adding anything to this recipe, I don't understand why it is there. So I decided to do an experiment, and make it into a video at the same time. I'd like to thank all my Patreons for helping the channel out.
