What kind of bleach are you refering to? There are a number of different bleaches used in black and white photography which are very different than those used in color processing.

I think you are asking liquid bleech in b&w photography. Make potasium fericyanide 25gm in 1000 cc normal water,then mix hypo 300gm in the solution -this is your stock solution. When you use take 1:2(camichel+water).This you can use in sepia toning. If your B&W prints in some area is dark you can bleach it - take a tea spun potasium fericyanide in 50ml water then give a tea spun hypo in it- mix it,then use cotton to bleach the darken area.

For film bleaching use kodak recomendad film intensifier.
