Amidol was and still is favored by many bromoilists because it causes no staining or tanning of the gelatin. The optimal bleach time seems to be about 4 to 7 minutes, but some prints require 10 minutes or more to tan fully. It is possible to separate the bleaching and tanning processes, though in general I find that a properly exposed and developed print will bleach in less time than it takes to tan, and so it is a waste of time to separate them.

I then rinse both sides of the print under running water before continuing to the fix–this keeps the plain hypo from becoming too acidic.

However, there are recommended starting points that have not changed much in the century since the process was invented.

Solution 2 Tanning Bath. Solution 1 can be used repeatedly, until bleaching times are too long. A very quick method for getting started with inking is to use a large boar bristle brush and ink the entire matrix until it is completely covered, with no regard for high or low values.
