I like all the environment and clothing care pros. I’ve also switched laundry detergent and noticed that clothes I air dry smell great, however clothes I dry with these dryer balls lose all “freshly clean” smell. I’ve used some essential oil on some loads but that’s kind of a hassle adding oil for every load. Going to switch scents to see if that helps. Overall, they’re good. Just miss the “clean” smell of dryer sheets vs these.
