Here’s the simple laundry secret many people swear by:

Step 1: Dissolve one cup of baking soda in boiling water.

Step 2: Add your yellowed white clothes to the mixture.

Step 3: Soak for one hour or even overnight for stubborn stains.

Step 4: Wash as usual.

Step 5: Dry your clothes outside in the sun — nature’s most powerful (and eco-friendly!) whitening agent.
No harsh chemicals. No bleach.
Just baking soda + sunlight = naturally brighter whites
