old chemistry

acp said:

I've been acquiring old chemistry from various friends & colleagues and I'm not sure what I should be keeping and using and what I should be disposing of. All chemicals are at least 2-3years old, and haven't been used in that time, but have been stored in the dark. Some are unopened, some aren't.

Any suggestions welcome. Here's the list:

Rodinal (unopened) Fine
Ilford Multigrade Paper Dev (unopened) Maybe - if its turned brown its no good
Tetenal Indicet Stop (unopened) Fine
Tetenal Mirasol Wetting Agent (unopened) Fine
Tetenal Superfix (unopened) Fine
Ilford Ilfosol Film Dev (1/3 left) Throw it away
Kodak Indicator Stop (3/4 left) Fine
Ilford Wetting Agent (1/4 left) Fine
Ilford Rapid Fix (prob unopened) Fine
Kodak Photo-flo 200 (3/4 left) Fine
Agfa Sistan Silver Stabliser (90% left) Fine
Tetenal Photo Corrector (looks over 10yrs old, unused) No idea
Kodak Polymax T Dev (3/4 left) Throw it away
Agfa Neutol Dev (3/4 left) Throw it away
Tetenal Gold Toner Virage (1/2 left) Unknown
Kodak Rapid Selenium Toner (1L ready to use - not concentrate) Probably fine
Microphen Dev stock (made Dec 2005) Throw it away
HC-110 Dev stock (made Aug 2003) Stock - throw it away
T-Max RS Dev stock (made Oct 2004) Throw it away

That's the lot. Thanks.
