I must have missed the Palmolive discussion. I know my bottle of Photo-Flo will last me for decades because I only use a drop or two, so I wouldn't save much by buying it at the grocery. I don't know, and don't much care, if dishwashing fluid is even a suitable substitute. But Borax, unlike Clorox, IS a proven substitute for many photo applications. I've always used grocery store washing soda too. It works, and is consistent. Nothing else matters. I would not use Clorox, even though it's bleach.
