I've bought many boxes of them and they've never had so much as a faint odor to them. I just got 2 boxes at walmart and when I opened one, it has a very strong scent. Similar to dryer sheets, I think (I'm not completely sure-I don't use anything scented in the wash other than spray and wash, but I have smelled the dryer sheet aisle at the store). Has something changed? And if so, is the scent noticeable after the wash is done?
