Hello guys.
I have found some old stock of developers of mine whish I bought years ago (about 10 to be precise). I wonder if it is still usable to provide "like new" results (or what to expect/how to adjust process in opposite case).
I have:
Xtol
D-76
HC-110
Microdol-X
Dektol
LPD
Microphen

All of them are unopened, most of them do not have stated expiration dates on packaging. (except Xtol which is far beyond these dates).
So are they usable or is better to ditch them and buy new ones instead? Thanks.

Sorry if I failed to find the relevant info here in the forum

You don't say if it is liquid or powder.

In many/most cases it will depend on the integrity of the packaging.
There is a good chance all of them will be fine.
EDIT
You don't want to mix them up before it is time to use them, because they only have so much life once mixed.
When it comes time to use them, I would proceed as follows:
END EDIT

With respect to the powder developers, I would open them and check for discolouration.
Assuming they are white powder, I would make sure that I tried a test roll before relying on film developers.
Microdol-X is no longer made, although Ilford offers a reasonable substitute.
HC-110 has changed, although the replacement is essentially functionally equivalent in normal use.
All the currently made Kodak products are experiencing supply problems.
LPD has been a challenge to get for at least two years.

If they are still in powder form in their sealed original packages, there is a chance that they are okay. Mixed up with water? Best to dispose of them, and buy fresh stock.

No, you only open them when about to mix them up. Otherwise the humidity could impair their quality.

Thanks clive - I meant to say that sort of thing, but it got lost in an edit. It has now been corrected.

I have had developers that remained unopened for decades. Always fine. Developers in original packaging will be still be good when only cockroaches inhabit the planet. If you thinking of throwing away unopened chemistry send it to me, I'll poay postage,

When you are ready to use it, mix it and test it.
