Thanks for all your help. Sorry if my questions are elementary, I 
have no chemistry background. I like the etch, and speed of the HCl 
and H2O2 etchant, and now the fact that I can reduce the waste to 
almost nothing. One last question about the storage of dry copper 
hydroxide powder. Does it react to anything, such as moisture, light, 
plastics, metals?

Thanks for your help, and to everyone else, this group is great.
