For a more natural approach to stain removal for clothing, keep your laundry room stocked with some simple, non-toxic household products.
Cornstarch or baking soda can be applied to grease stains, gasoline, and even some food stains such as acidic salsa, to help quickly absorb stain and odors.
Sweat stains and dull whites
Lemon juice or white vinegar work great as natural bleaching agents. Mix either to a 1/2 cup of warm water and add to a wash cycle to help brighten whites. For tougher stains, add lemon juice or white vinegar to some warm water and let clothes soak for a period of time before washing. Laying whites out in full sun also helps brighten whites too.
Dark stains such as chocolate or ink
To remove dark-colored stains such as chocolate, soak the clothing in a bowel of glycerin for 30 minutes. For tougher stains, soak the area of clothing in a small amount of hydrogen peroxide. Ink stains can be soaked in a small amount of milk.
Mild dishwashing liquid can also be used as an all-purpose stain remover, apply a small amount directly to a stain and gently rub, or mix into with water and use for soaking stained items.
