I just found a package of old cidr's that have never been opened. They are outdated but I am wondering if they would still be usable. Or should I just toss them?
How outdated are they? Manufacturers are required to guarantee a date that they will be good but if unopened I would not be afraid to use them if they are 6 months outdated or maybe more.
If they are still sealed I can't see how they can go bad. All that said I'm not a believer in CIDRs, I believe the irritation caused isn't conducive to high conception rates on AI.
