Re: MURATIC !
I have a shelf full of old glacial acidic acid and some other old photographic diazon chemicals used for blueprint machines.......... Like a dummy I kept some lenses on a shelf beneath these , some of them quite valuable........ For some reason some of the plastic bottles just got brittle and cracked by them selves.....I almost lost maybe $5000 in LF lenses because of this..... It did damage some of them and I lost the black finish but they were the cheaper process lenses and the loss was only a few hundred... I now store everything in commercial heavy nalgeen bottles... Also in the basement where I store Muratic acid I noticed the metal shelf severely rusting out and all the paint cans on the self below and above were rusted...... John Cremati.
