Hi Murray,

I think I saw your posts on this site at another thread. How is your experience with homebrew rodinal?

The Australian MSDS docs usually showed more ingredients than the USA ones or even the EU ones. For what it's worth, KBr is shown. Of course the percentages are not much of a guide for recipe hunters.
