This also works with clothes. Before, when I smelled my clothes my nose didn't find any smell, but now I can smell the BO on clothes and it is different with different antiperspirants or deodorants. Sometimes like onions and garlic, sometimes like other people's BO but really strong, sometimes musty. I wonder if different deodorants kill different bacteria but I always have some bacteria species that survive. And once I tried Wild and I've never smelled anything so weird I can't even describe it, but it was bad. Good luck!
