Homebrew PCBs

I don't worry about agitation. I simply leave everything still, and 
float the board on about a quarter to half inch of echant. The "used" 
echant is heavier than the fresh, so the etchant naturally keeps the 
fresher stuff at the surface of the board. The only drawback to this 
method is it only does one side at a time.
