Homebrew PCBs

... and if you add salt to the vinegar, you get dilute hydrochloric  
acid and it strips off any oxide like it was never there (try it with  
a filthy dark brown copper coin). I'm kinda through my "honeymoon"  
period on DIY PCBs, and probably wont be etching a few for a while,  
but I suspect the salty vinegar dip would be highly effective,  
provided you've got any oily stains off. I'll certainly be trying it  
when I do make a PCB again.
