Baking soda can help remove pungent odors from laundry even when they linger after repeated washing. A cup of Borax and washing soda also make good odor removers for laundry, but are relatively ineffective as stain removers.
Try soaking in a baking soda and water solution to rid them of the sweat smell.
Try soaking clothes that smell of smoke in a baking soda and water solution before washing in the washing machine.
If you have clothing with gasoline, oil, or other mechanical smells, place them in a bag with baking soda. Leave the bag sealed for a day or two before washing.
If smelly clothes cannot be washed right away try sprinkling baking soda directly on them. Wash them as they are when you have the time.
For everything except pet urine smells - put white vinegar into both the fabric softener and the bleach dispenser of your washing machine, with the normal amount of laundry detergent. Run the load normally, and you should have success!
