When I switched over from FeCl to CuCl I used the same plastic
tray with snaps on all four sides that I had used for several years.
It had a red plastic seal. A few weeks later I went to use the CuCl 
to etch another board and the cover was really loose. The CuCl 
had destroyed the seals; turned them into a white, crumbly substance. 
There was a tray containing several partially discharged batteries sitting
beside the tray. The terminals on both ends were severely corroded.
