I sometimes have to use a 3% solution of acetic acid to clear the sediment or "haze" I get on prints after doing sepia toning (with thiocarbamide). I find I only get this haze when I am doing full sepia, ie: bleaching all the way back and toning to completion.

Anyways, the 3% acetic acid clears this. That tip must have been in the Darkroom Cookbook. I have literally gallons of Kodak Indicator Stop Bath, and only a small bottle of 28% acetic acid. Can I use the Kodak Stop bath instead? Does anyone know what the working strength of Kodak Indicator Stop Bath is?
