Hi I am sure someone can help me. What should I do with chemicals used in making pcb's? I have a winchester of used Ferric Chloride which I would like to safely dispose of. Does this need any treatment and how should it be disposed of? Info on any other common chemicals would also be appreciated. Is there a common philosophy such as kill all chemicals etc? Thanks Graeme
