Laundry as White and Pure as Milk: You Only Need This Ingredient

Soak clothes in warm water + 1 cup baking soda for 1–2 hours

Then wash normally

Important tips:

Works best on white cotton and light fabrics

Avoid overusing on delicate materials like silk

Don’t mix excessively with strong chemicals

Bonus trick:

For even brighter results, combine baking soda with a little white vinegar (added during rinse cycle—not at the same time)

It won’t turn old yellow clothes pure white instantly, but with regular use, it noticeably improves brightness and freshness.
