This is kind of interesting. I was at the JOBO FAQ and one of them was:
"Why can't I use stabilizer, Photo Flo, or other wetting agents in my JOBO tanks?". I figured that probably had to do with foaming but was surprised when I read their answer: http://www.jobo-usa.com/faq/stabilizer_on_reels.htm
To tell the truth in many years of working in commercial photo labs. I have never noticed a problem with steel reels or tanks or racks or rollers. I have seen some munged up plastic reels but never really made the association to wetting agents or stabilzers.
For what it's worth, I thought that I'd pass it along.
