Simple Ways to Remove Yellow Sweat Stains from White Shirts

4. Hydrogen Peroxide + Baking Soda: For Stubborn Stains
When stains are particularly tough, combining hydrogen peroxide and baking soda creates a powerful stain-removal solution.

How to Use It
Mix the ingredients: Combine equal parts hydrogen peroxide, baking soda, and water to form a paste.
Apply generously: Spread the mixture over the stained areas.
Let it soak: Allow the shirt to sit for about one hour.
Wash normally: Launder the shirt afterward.
Hydrogen peroxide works as a gentle oxidizing agent, helping break down the stain while baking soda lifts it from the fabric.

Tips to Keep Your White Shirts Looking Bright
Prevention is just as important as stain removal. Here are a few tips to keep your shirts looking fresh:

Wash shirts soon after wearing to prevent sweat from setting into the fabric.
Air dry whenever possible, especially in sunlight, which naturally brightens white fabrics.
