As I say this I realize it sounds impossible but, I have been using California Duster for over forty-five years, without interruption (since I owned my very first car). Starting about four or five years ago, the dusters began to get more cheaply made - much less dense. They still work okay, but not near as well as "the original". This last one, the Dash Duster, was the worst yet, most cheaply made. May be time to start looking at the competitors models.
