If the bags are sealed, the propellant should hold up pretty well.
Particularly WL tends to absorb moisture and swell once the bag is opened.
If the grain won't fit in the liner tube, toss it. Otherwise, do as was
already mentioned: rough it up a bit with some sandpaper to de-crud the
Older grains can be difficult to ignite. The simple solution for the multi
grain reloads is to swap the TOP grain (the one next to the delay where the
ignitor goes) with a fresh one from a motor that uses the same type
propellant. That's what I did with my 13 year old I284, and it was instant
on at ignition.
