[pure-silver] Re: Cleaning Nova Clips?

One thing Jobo cautioned against was using household bleach to clean their Jobo 
processors as it weakens the plastic.  I would try tray cleaner which is 
basically potassium dichromate and sulphuric acid.  I've not seen it for sale 
in the stores for a long time so you may have to find the Kodak formula for it 
and make it yourself.  It's not a one use solution as I re-use mine over and 
over when cleaning the developer trays.  It does not completely clean them of 
stains, but at least prevents transfer of whatever developers leave behind 
after only water rinses.

Subject: [pure-silver] Cleaning Nova Clips?

Hi,

I have been using a Nova Quad vertical tank for processing B&W paper. I
am very statisfied with this system as such. Now my clips are getting a
bit dity, and I am experiencing some streaks of unfixed emulsion
starting from the 2 punctures and/or between the 2 punctures (made by
the nails in the clip). 

Perhaps the one has to do with the other, so I want to clean the clips
anyway. 

Brushing in hot water helps, but not completely. Any tips on a good
cleaning method for these clips?  Can a bleach be used (I know you can
use the unit for colour work, so I assume that the clips can stand some
bleach)

Thanks & best,

Cor
