there isn't a delete by type for the jiggle deformer that i know of... the only thing i can think of besides the hypergraph is just to delete the object's history (not sure if you have lattices, binding and the such on your model)
and if you don't have any effects going through the jiggle deformer itself, in hypergraph just show the up and downstream connections and delete the nodes called jiggle and jiggle cache
hope that helped
