While it is always a good idea to spot test a garment when using any product, baking soda is safe to use in laundry and will not cause color fade. There are many benefits to using baking soda in your laundry however, let's look at some of them.
Prewash Stain Removal
Baking Soda is very good at removing stains prior to washing. Make a paste of baking soda and water to the consistency of cake frosting, and allowing it to sit on the stain for five minutes before you wash. This is very effective on greasy stains.
Brightening Colors and Whitening Whites
Baking soda will also brighten colors and whiten your white clothes, just add a 1/2 cup of baking soda along with your regular detergent in the wash cycle.
Some commercial detergents are harsh on fabric and will cause the fabric to be especially difficult to iron and to feel scratchy to the skin. Instead of using commercial fabric softener which is not only expensive but may also prove harsh to sensitive skin, try using baking soda. Pour 1/2 cup of baking soda to your final rinse water and let your items soak for 10 minutes before running the cycle.
Acid spills happen all around us and most happen on our clothes, but don't let them worry you if you have baking soda on hand. Acids like vomit, urine, ketchup, vinegar, citrus fruit juices and battery acid can all be neutralized by using baking soda. Simply rinse the item in water, sprinkle some baking soda on the stained area and wait for 5 minutes before rinsing again or putting the item through your regular wash cycle.
This hack is especially handy for people who smoke, those who sweat a lot, and for those with children who still wet their beds. For clothes with bad odor, simply soak your items in baking soda mixed with your regular detergent for about 30 minutes to an hour before rinsing with clean water.
In addition to general laundry, you can also try a dry cleaning method on suede, by sprinkling baking soda on, letting it sit, and brushing it away.
