I haven't tried using eco-bleach for toning, but my understanding is
that you need to use a re-halogenating bleach, and eco-bleach is not
that. It's more like the dichromate R9 bleach, and not what you need
for conventional toning.

Greetings friends and colleagues,
When reversal developing 7363, I’ve been happily using an eco-bleach
alternative based on Ricardo Leite’s recipe with some tweaks
suggested by Dawn George. It works really well! Ingredients are 9%
hydrogen peroxide and 5% acetic acid.
Question: can this eco-bleach also effectively replace standard bleach
when tinting/toning film, or does one need to use potassium
ferricyanide + Potassium bromide for that?
If yes, any data on how long to bleach the film before tinting or
toning?
thanks kindly,
Sarah Bliss
