Homebrew PCBs

Hi - HDPE = High Density Polyethylene. In general, this  is a long chain 
saturated (viz., no double bonds) chain of carbon and hydrogen and is very 
inert.  Chances are it will do just fine - we store hydrofluoric acid, which 
will attack glass, in these containers.

However, the salt formation has me a bit puzzled - where did this form - all 
over the container or around the lid?
