3 washing questions: 1. I once came across a solution for testing washed dried prints for excess fixe r residue. You dropped a little on the print border and if it emerged darker tha n cream-coloured it indicated fixer contamination. Can anyone tell me the produc t name and supplier, or is it a simple chemical solution?
2. I looked through this site's archives and came across something called the HT -2 test for checking wash efficiency. Can anyone tell me what this is?
3. Does anyone use the Ilford archival washing sequence using Kodak Hypo Clearin g Agent instead of Ilford Wash-aid? The formulas are slightly different, Ilford' s seems to contain more chemicals designed to expel fixer from the fibres of the paper, so I am a little cautious about substituting it with Kodak's [far cheape r] Hypo Clearing Agent.
Any feedback gratefully received.
