You dont have to boil it . Just rinse the matrix thoroughly in tank water and it will be as good as new and the effectiveness wouldn't decrease. Also, seachem have claimed it does not need replacement at all, since its natural stone, it will not breakdown like other biedia example " biohome " or ceramic rings or substray pro, getting smaller and smaller . Personally, i find that seachem makes great stuff like purigen, prime, excel, fluorish and so on..
