im at 150 but only 100 of them are premium microfiber from adams and griots. the other 50 have the made in china tag and aren't good microfiber, basically like walmart or part store quality . so to get rid of them I use them during the winter to wipe down tires wheel wells, wheels, any exterior trim and a wipe down of the engine by. but my goal is not to have them so when I am done with the bad microfibers, there gone and never coming back on my shelf
