Hello Folks, as usual, I seek the wisdom of fellow APUGers. I bought my first batch of Perceptol, and I'm about to mix it up. There appear to be warnings all over the place (and in many languages!) about the toxicity of the A and B parts. After I use Perceptol, how should I get rid of it? I normally take my fixer and selenium to the local Household Hazardous Waste disposal place, but I just pour developer and stop down the drain. Should I also put the used Perceptol in HHW?
