White clothes can gradually turn dull or yellow from sweat, body oils, detergent buildup, and frequent washing. Before reaching for harsh bleach, there’s a simple ingredient many households already have: baking soda.
It won’t magically restore every stained garment, but it can help freshen laundry and support your regular detergent.
How to Use Baking Soda for White Laundry
For a normal washing-machine load:
- Add your usual laundry detergent.
- Add about ½ cup (120 g) of baking soda to the wash.
- Wash using the hottest temperature that the garment’s care label allows.
- Dry according to the fabric instructions.
Baking soda can help neutralize odors and may improve the cleaning performance of detergent, leaving whites looking fresher.
For Yellow or Sweat Stains
For small, stubborn areas, make a paste with baking soda and a little water. Apply it gently to the stain, leave it for a short period, then wash as usual.
Always test a hidden area first, particularly on delicate fabrics.
Don’t Mix Cleaning Products Carelessly
Baking soda is not a substitute for proper stain treatment, and more isn’t always better. Never mix household cleaners unless the product instructions specifically say the combination is safe.
Also check the care label before using hot water or any whitening treatment.
Bottom Line
If your white laundry looks dull, baking soda is an inexpensive addition that may help with freshness and everyday grime. For heavily yellowed or stained clothing, however, a laundry product specifically designed for whitening may work better.
A little care with washing temperature, detergent, and drying can make just as much difference as the ingredient you add.
