As the photographers in this thread have stated, Kodak Photo-Flo is a 'wetting agent'. It decreases the surface tension of water to keep it from 'beading up'.

It does not 'clean' anything. It's not soap, detergent, or any kind of cleaning agent.
Back in the 1970s, there was a rumor amongst the stoners (yeah, literally) that they could use Photo-Flo in place of something like Discwasher D3 to dust records. Bad idea. First of all, it's highly concentrated. Using is full-strength is not only very expensive, it also leaves horrible white, crusty, streaks on your records, and gums up your Discwasher brush. How do I know? I had stoner friends, and like a moron, I listened to them. I learned the hard way.
The way Photo-Flo is used with film is this: After developing and rinsing your negatives in the kitchen sink, you do a final dip-rinse in a very diluted solution of water and Photo-Flo. This causes the negatives to be wetted with water that has very low surface tension (when you see water 'bead' on a waxed car, that's high surface tension). Therefore, when you hang the negative up to dry, the water drips off and doesn't leave much, if any, of the minerals and detritus normally found in tap water behind. It's not the water we photographers are concerned about; it's the stuff in the water that stays behind if the water remains long enough to evaporate instead of dripping off.
So, let's translate this to vinyl records. If you are washing them, such as the way I do it, in the sink, you might want to use something like a very diluted Photo-Flo solution as the final rinse if you are NOT going to wipe the records dry and you ARE going to let them air-dry. Otherwise, I cannot think of much use for Photo-Flo in record care.
It makes no sense to use it if you're wiping your records dry after washing in the sink, since the towel you use to wipe them dry should remove the remaining water and most if not all of the junk that's suspended in the rinse water (minerals, etc). In other words, although there may be some microscopic water remaining in the grooves, it's not going to run out in drops anyway; it's going to evaporate over time. It will leave behind deposits whether you have Photo-Flo in the water or not.
It also makes no sense to use it in day-to-day dusting of records in place of something like D3 or D4 or whatever. Again, nothing is 'running off' of the record, so any remaining moisture is going to evaporate, leaving behind whatever is suspended in the water.
I don't know much about record cleaning machines, but I would suspect that it would not be of any use in them either. If the water is not actually running off the record, a surface-tension reduction isn't going to do a thing for you.
My recommendation would be that unless you are washing records in the sink with tap water and NOT drying them with a clean microfiber cloth when done, there's nothing that Photo-Flo does that would be of use to anyone cleaning records.
