Wash Test

The Photo Formulary, Residual Hypo Test.?......says it works with Hypo Clear but not Hypo Eliminator.
Does the Heico Perma Wash pose a problem for this test.?
Thank You

from their site.....
"The test will give accurate results if the print or film has been treated with Hypo Clearing agent and washed in water or just washed in water. The test WILL NOT give accurate results if Hypo Eliminator has been used in the washing procedure. Hypo Eliminator contains ammonia which complexes with the silver ions in the Residual Hypo Test Solution decreasing their effective concentration".

Wash-aids like Kodak Hypo Clearing Aid or Heico Perma Wash are different than Hypo Eliminator. Hypo Eliminator is no longer being made or recommended. As it turns out, completely eliminating all traces of thiosulfate based fixers is actually bad for film and paper.
Wash-aids like Kodak Hypo Clearing Agent or Heico Perma Wash or the Ilford equivalent aid the washing process and result in the residual fixer levels being reduced to the target amounts.
So the answer is: no problem

Ah.....OK...Thank You
