You can try the gold spinning laundry detergent, which is the kind that doesn't need to be flushed after washing and soaking. Try to see if the underwear still smells. I just bought it. It smells and is a waste. Just try it. You can't return it because you have lowered the label. I suggest you wash it again to see if there is a pungent smell. If so, you don't want these underwear.
