Alright, so I mixed up some chemicals about a year ago and then promptly had no free time at all to use them. They've been stored in my fairly cool-temperature basement, in dark bottles. Last night I decided to take a look at them as I assumed they were no longer good. However I hypochecked the Fixer and it was not cloudy, the indicator stop bath was still yellow, and well I'm not sure about the HC110 but it looks and smells normal. I'm assuming there's a difference between chemical exhaustion and just plain old expiration (ie the chemicals have weakened over time and won't produce consistent results)? But before I dispose of them I just want to confirm with you kind folks (who know a lot more than me about this kind of thing) if I should or not.

Thanks!
