I miss that sharp, flowery smell from detergents. There I said it. Charlie's soap has no fragrance, and I want my clothes to smell something other than merely "fresh." It's like when I was weaning from deodorants, I would sometimes take the top off the Old Spice we use (now the Old Man uses it exclusively) and would just take a quick sniff, just to remember. I can't imagine how people use scent-free detergents, because I need that smell, man!
So, I gave in and have started putting a 1/2 teaspoon of fragrance oil in with the Charlie's Soap. I was worried it would leave oil stains on the clothes, but we put the detergent in through the center well of our washer, so it's easy enough to add the fragrance so that it is dispersed more evenly in the wash water. And the clothes have an ever-so-slight smell of cucumber and melon (the Bath and Body Works "dupe" I have a lot of and need to get rid of). When they come out of the dryer they have a slight trace of scent, just enough to feed the olfactory nerves, so I've been happy.
