Spilt mositure absorbing crystals - please help

Please could anyone offer me some advice as to how to remove mositure absorbing crytals from caravan cushions.  I unfortunatley left the tub on a shelf and the contents split all over the cushions as we travelled.  Now the cushions always feel damp.  Ive tried clearning the cushions and drying them out but once they are put back in the caravan they soon feel damp again.  Any help would be great - thank you
