Homebrew PCBs

Hydrogen Peroxide is still used in food processing to disinfect 
packages. For aseptic packaging, milk cartons are first sprayed with 
H2O2 and then heated. The heat decomposes the H2O2 to water and O2 
and the carton is then filled and sealed. This all happens in a 
matter of seconds.
