K.N.
Funny -- after several years of using unscented detergent I've come to realize how very smelly "normal" detergents are. And I just don't like it!
When I need to get an odor out of clothes, I put a cup of baking soda in with the clothes as I load the washer and add a good bit of vinegar in the fabric softener dispenser. I'll add an extra rinse to the cycle & then hang clothes out on a line to dry. This usually helps a great deal.
Good luck!
