I would like to use coffee as a developer, I'm just having trouble finding washing soda. I found a dish washer detergent that lists sodium carbonate as the first ingredient, with only a couple other ingredients on the list, could I get the same results as using pure washing soda?
I think that I may have found Arm and Hammer Washing soda, but it's in quite a large container.
