How long's it good for? I've got a bottle of the stuff that's been sitting around for about a year and wondering if I should get some new stuff.

It is fine. I used to work in a large camera store selling darkroom equipment and supplies.

As a professional photographer of over 30 years, I would not hesitate to use PhotoFlo from my big jug that goes back to the 1960's. It is just a wetting agent. No active chemicals.
Diluted tank solution photoflo can get dirty though in a tank, since its purpose is to lower the surface tension of water, any dirt that touches the surface of the liquid will immediately fall in.

I found a bottle not too long ago in a box of old darkroom stuff. One of the first bottles I bought, back in 1980. I used it, and it works just as good as new.

I'm still using a bottle of Photo-Flo I bought back in 1983. It replaced a bottle I originally purchased in 1968. Too bad they don't sell it in very small bottles.

I've got one with George Eastman's handwriting on the label. Go with it. Photo-Flo is nothing more than a very pure detergent, so there isn't anything in it that's likely to spoil or go bad as long as you keep it tightly capped so it doesn't just evaporate!
When I bought mine the sales person declared that it was a lifetime supply. I am still around, and it is still good.

Yup, my Photoflo is from the 70's and it still works fine!
