After my mother-in-law passed away, I started helping my father-in-law with laundry and other chores. He asks me to add aspirin to the washing machine every time I do the laundry. When I asked him why, he said that’s how his wife used to do it. Any idea what aspirin does?

Yes! Your father-in-law is actually onto a neat little laundry trick—aspirin can brighten whites and remove dinginess. Here’s how it works:

Why Aspirin in Laundry Works

1. Contains Salicylic Acid
   • Aspirin’s active ingredient, salicylic acid, helps break down mineral deposits, sweat, and light stains that make whites look dull.
2. Whitens and Brightens Fabrics
   • When dissolved in water, aspirin can restore the brightness of white clothes without harsh bleach.
3. Gentle on Fabrics
   • Unlike bleach, aspirin is less likely to damage delicate fabrics when used correctly.

How to Use Aspirin in Laundry

1. Crush 5–6 regular aspirin tablets.
2. Dissolve them in a small amount of warm water.
3. Add the solution to your laundry (especially whites) in the wash cycle.
4. Wash as usual.

• For tough stains or dingy whites, some people soak clothes in the aspirin solution for 2–3 hours before washing.

💡 Tips

• Works best on white cotton or linens.
• Not necessary for colored fabrics, as aspirin is mild but can sometimes affect dyes.
• Always check care labels if washing delicate or synthetic fabrics.
