I've seen quite a number of posts on this forum implying that Photoflo/wetting agent residues left in developing tanks are a problem. What exactly is the issue? Nowadays I use Tetenal Mirasol rather than Kodak Photoflo, but through the last 40 years or so I have used several different brands of wetting agent including (originally and for many years) washing-up liquid. I rinse my tank after use, but not assiduously. I have never noticed any problem that I could ascribe to wetting agent residue. Instinctively, I would have thought that something that breaks down surface tension is likely to be beneficial rather than otherwise, but I'm probably wrong. Please enlighten me.
