Bleach: Lemon juice is an all-natural bleaching agent. Pour lemon juice on stains (test for colorfastness in a hidden spot first) and hang in the sun to dry, then machine wash as usual. For an allover white brightener, replace the bleach in your wash cycle with 1 cup of lemon juice.
Soak Solution: For very soiled or perpetually dingy items (not just clothes—think towels, sheets, tablecloths), soak overnight in hot water with ½ cup lemon juice. Machine wash as usual. You may subsitute lemon juice using white distilled vinegar.
Odor Eliminator: Adding ½ cup baking soda to the rinse cycle will neutralize odors and leave your laundry smelling fresh without fragrance.
Brightener: To give your regular liquid laundry detergent a stain-fighting boost, add ½ cup baking soda to your regular wash cycle. Baking soda helps neutralize the pH in your wash water, improving the way detergent interacts with your clothes. Your whites will come out whiter and colors brighter.
Stain removal: A paste of baking soda and water can be rubbed into tough stains like blood,wine, perspiration, and vomit to kill the odor and help remove the stain.
One cup of white distilled vinegar added to the laundry rinse cycle will keep your clothes soft and colors bold while eliminating odors caused by detergents, smoke, pets and many others.
