My nana swears by this trick for cleaning yellow stains off white pillows with almost 0 effort. Here’s how it works.

3. Add half a cup of baking soda and half a cup of white vinegar to the water.
4. Submerge the pillows in the solution, ensuring they are fully soaked.
5. Let the pillows soak for at least 30 minutes.
6. After soaking, gently squeeze out excess water and transfer the pillows to your washing machine.
7. Wash the pillows on a gentle cycle with a mild detergent.
8. Once the cycle is complete, dry the pillows thoroughly, preferably in a sunny spot or using a dryer on a low heat setting.
