| Part B, | 120 ml          |

===== Instructions for use =====
Immerse the wet print in a tray of working solution. Don't agitate, agitation tend to cause an uneven result with more bleach on print edges. Treat for approx 5-10 sec. Thereafter, rinse the print in running water and evaluate. Repeat if necessary. When satisfactory, fix and wash the print as normally.

A strong and rapid bleach is better for increasing (local) contrast. A weaker and more slowly working bleach is better for overall print reduction.


===== Notes =====
This recipe is from Darkroom Cookbook[(biblio:Anchell2008)], Formula #173. 

It is not clear (to me) why the KBr is needed. Most other recipes does nor contain KBr. Internet forums suggests solution A contain KBr since it can then also be used as a rehalogenating bath in a toning process?
