Homebrew PCBs

Agreed, glass is far better but...  31% HCl is sold in the US
(probably elsewhere) in plastic gallon bottles.  I've had one sitting
in my basement from when I finished my remodel and they acid washed
the brick.  Its about 1/2 full and no problems (no residue, container
was fine).  SG test showed it to have the correct SG.  My remodel was
finished 3 years ago.  The recycle logo (2) on the bottle says it HDPE.
