It will probably speed it up. You aren't really using CuCl etchant, it's HCL 
and HO2, and can only be used once. If you treat it properly and get the 
chemistry right, it may be turned into CuCl etchant.

I use plastic milk bottles to store FeCL3 and CuCl etchants. The HCL I've 
got came in a plastic bottle.
