Theoretically they should be ok. Practically though, I noticed salt deposits near the openings which means the conc. of the solution inside changed. You also want to check for fungal growth, which is a posible when the solutions where not properly stored.
If the solutions precipitated out of solution you can generally disolve them back, just increase the temperature and stir. For example you could put the bottle in a pot filled with warm water, wait for the bottle to warm and give a nice shake ( of course watch out for pressure buildup and different boiling points)
I don't know what happens with the iron chelators in all this time.
On hiatus till later this year
