PCB Etchant made of: 2/3 Hydrogen Peroxide [10%] (H2O2), and 1/3 Hydrochloric Acid [30%] (HCl)
Turns out to be very effective, the video is 1:1 time scale.
A more detailed video is coming up, explaining the whole process of making PCBs at home. This is just a test video!.. PCB Etching With HCl + H2O2. (First Test)](https://i.ytimg.com/vi/PlIZs2uOmus/mqdefault.jpg)
