It is called polymeration.   The long molecules of the plastic  start to
develop interconnections between each other and the plastic  yellows
and can even become brittle if it is severe.   If that is what  has happened
the best thing would be to get a can of white "Fusion" paint and  apply
that to the enclosure.
