You need the copper to be super *oil free* - i.e. keep your grubby
fingerprints off it!  You normally don't need to make the copper shiny
or remove the oxides (in a CuCl bath, the oxides etch faster than copper
anyway).  Shiny is actually bad if you're using transparencies, where
mechanical grip on the copper is key to keeping the toner there.
