Unopened HC-110 developer, 2 1/2 years old - toss or use?

[RedGreenBlue]

I just found an unopened container of Kodak HC-110 developer that was purchased 2 1/2 years ago. Kodak says the shelf life is 6 months, but I would like to use it. I can just try it out on some test shots, but thought I'd ask here if anyone has used HC-110 this old and if so, what were the results?

Thanks,
Scott

Unopened? - Use it.
I've used unopened hc-110 that was 15ish years old just fine.
Unless it is dark brown (oxidized), have at it.
If it is brown - test it, but i hear even then it will likely work fine.

Even if opened, probably fine if not dark brown as noted.

Super. Will use it. Appreciate the advice.

My HC-110 was opened 2 years ago, it is dark orange and still works just fine, I'm sure your bottle will be the same.

Use it!

I'm using four year old stock HC110 (dark amber glass bottle) and it's looking fine. I don't recommend that length of time however ;)

Hexk my opened working bottle of HC-110 is older than that. Use it!

I'd use it then refrigerate it. L

I've used 5 - 10 year old HC110 with no problems. Maybe when the archeologists dig us up 5000 years from now it will still work - if they remember what film was..

When I recently unearthed some ancient (1988 expiry date) 11x14 Tri-X (never refrigerated - stored in numerous hot attics over the years)...I naturally opted for some of my "vintage" HC-110 - long-ago opened bottle with remaining contents as black as a good stout - and, lo and behold...got this as my reward:178390

HC110 is not Rodinal. My bottle is yellowish and clear, almost full, but with about one year of being opened. I have not been able to develop some film, so I tossed.

HC 110 as sirup and undiluted Rodinal last forever !
