Thanks for all the responses - I was away on a cycling trip and am just back to my computer now.
I'll try Kodak Indictator Stop Bath at a 1:30 ratio and see if it does the same thing. The "haze" clears so quickly - in less than 10 seconds. It is a necessary step for me, it seems.
Just for the record, I use a ferri/bromide bleach (B1 from the DuPont Varigam formulas) full strength, and bleach the image back fully. The toner is a sodium hydroxide/thiocarbamide formula (T1). The "haze" is evident in the deep blacks when held to light. I suppose I could try and make these with distilled water and see if the problem is a product of the Toronto tap water.
Again - thanks for the help!
