Washable hats, gloves, scarves, headbands, etc can be soaked in baking soda/water solution to rid them of the "sweat" smell.
Mechanical Smells
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.
In a Hurry
If smelly clothes cannot be washed immeadiately, sprinkle baking soda directly on them. When you have time, wash as is.
Spit-Up
Dry baking soda rubbed directly on clothing can remove the smell of vomit or baby spitup.
