I am a new user of Charlie's soap (liquid). I use about 1/8 cup in my front loader on DH's dirty work clothes; however, they don't seem to come out free of odors (mostly the sweat smell). I know years of using commercial laundry detergents with strong fragrances have spoiled me, but at least it covered up the sweaty smells. Should I add white vinegar to the rinse for fresher smelling clothes? Any suggestions?
