I always felt that electronics is a bad thing to put in a dishwasher machine. You are going to use it for washing things that you eat with. And old computer stuff contain led and other bad things.
For surface, I recommend a certain thing we have here in denmark. I have no idea what it is sold as, brandwise in other countries. Here it is names "Rodalon", and is a liquid that can be used to remove cat-pee odor, strong smell of sweat on clothes and other things like that. I do not recommend it for curcuit boards, as I have no idea on how acidic or alkaline it is. All I know is that it kills fungus, kills bacteria, removes bad odor and do not contain chlorid so it will not bleach. Do not mix it with soap or anionic surfactants. Just mix with water or use undeluted.
There is something about pumpkins and stuff, in english here below. They explain what rodalon is a mixture of...
