Type of Stain

Rust 
 * Cream of Tartar
* Hot Water
* Lemon Juice
* Salt

To remove rust from clothes, you can cover the stain with cream of tartar (gathering up the edges of the item to keep the powder on the spot), then dip the spot in hot water. Let stand 5 minutes, then wash as usual. If the item is white, you could also apply lemon juice to the stain, rub with salt, and let it bleach in the sun.
There are also several commercial products available that are designed to remove rust stains, such as Zud or Whink.

Smoke Odor 
 * Ammonia
* Washing Soda
* Vinegar

To remove the smoke odor left in clothing from a fire, add 1 cup of washing soda, 1/4 cup ammonia and 1/2 cup of vinegar to the wash load. Be sure not to add bleach, as it will react with the ammonia. You can also add 1/2 cup vinegar to the rinse to remove any lingering
