Ah, this is one of those simple laundry hacks! 👕 The “1 ingredient” trick usually works because it targets the sweat stains and deodorant residue that cause yellowing. Here’s how it works:
How to remove yellow sweat stains using a single “ingredient”:
- Use baking soda – This is often the hidden ingredient behind “very white clothes” tips.
- Make a paste: 4 tablespoons baking soda + ÂĽ cup water.
- Apply it directly to the yellow stains.
- Let it sit for 30–60 minutes.
- Wash normally – After letting the paste work, wash your clothes in the hottest water safe for the fabric.
- Check before drying – Don’t put clothes in the dryer if stains remain, as heat can set them.
Why it works:
- Sweat contains proteins and salts that can yellow over time.
- Baking soda breaks down these proteins and neutralizes odors, restoring whiteness.
đź’ˇ Extra tip: For stubborn stains, you can also soak clothes in a mix of baking soda and water overnight before washing.
