[pure-silver] Re: OT-- chroma list

MessageDear Dave,

     Today's posting on the Pure Silver - Chroma list concerns enormous good 
fortune with a sting in the tail.

     I bought a cubic yard of Jobo tanks from a eBay sale last month. They are 
the 2500 series and were used to run B/W processing in a Sydney commercial lab. 
I guess most of them were used in the rotation mode, but 3 seem to have been 
set on end and used as deep dip tanks or washers. Hard to say, but the end 
result on the roataion ones has been a silvery-black deposit on the interior of 
all the components while the vertical ones have a spectacular encrustation of 
old fixer on the outside.

    I have wiped most of the silvery gunk from the tanks but wondered if minute 
residues will affect their use in a C 41 process. Any ideas, people?

    And as for the fixer crud - I think the tanks will be fine if I can get it 
off. Will conventional acids like hydrochloric or sulphuric do it or do I need 
to go more exotic?

     Uncle Dick
