[Sca-cooks] Shelf life for Rosewater, Orange flower water

[Sharon Palmer]

I have an opened, nearly full bottle of Rosewater and an upopened 
bottle of Orange flower water, that are each several years old.   I 
just saw an interesting modern recipe that called for orange flower 
water.  I wonder if I can use it or should toss them both.  Any idea 
what the shelf life is?
