Very sensible. In the late 1980s the customer rep for Kodak Austalasia in Melbourne - a gentleman named Andrew Brown, who some here may remember for his excellent advice and PR services for that company until he left their employ in the '90s - told me the "problem" with PhotoFlo was that most users didn't follow Kodak's instructions properly.
As John writes, a few drops in water as a final rinse for films will do the trick. I've done this, and the bottle I bought from Vanbar Photographics here in Melbourne in 1998 or 1999 is not yet empty. It will last me for another long while. Maybe longer than I will...
Andrew also recommended a good option to periodically clean one's developing reels of any chemistry guck - a medium hard tooth brush in a sink partly full of warm to hot water and a little more dish detergent than one would ordinarily use for the household dishes.
I've been doing this since then, and have never had any problems with films sticking on reels.
Another good bit of advice from Andrew at the time was - always be sure your reels are bone-dry when you load them.
Common sense prevails.
