Do clothes have a shelf life for when the smell doesn't come out anymore? A couple of my shirts have an odd odor to them. I thought maybe it's because I overloaded the washer, but washing them again with a smaller load didn't change anything. I ran the washer through a cleaning cycle, so we'll see what happens next time.
Make sure you run it with a little bleach so you kill any mold in the washer.
Could it also be your closet or dresser? We have a storage bench for the blankets , but the blankets end up with an odd smell from it. I've been putting scented dryer sheets in it and it helps a little.
You might also try hanging your clothes up in the bathroom when you shower. The steam will not just take out some wrinkles but might help with the smell.
