If your T-shirts or hoodies still smell like sweat even after washing — especially under the arms — it’s because bacteria, deodorant, and body oils get trapped deep in the fibers. Here’s how to eliminate odor completely.
1. Pre-Soak With Vinegar (Most Effective)
Vinegar dissolves sweat salts and deodorant buildup.
- Mix 1 cup white vinegar + 1 liter warm water
- Soak garment for 30 minutes
- Wash as usual
2. Use Baking Soda Paste for Underarm Odor
- Mix 4 tablespoons baking soda + water
- Apply to armpit area
- Scrub gently with soft brush
- Let sit 20 minutes
3. Use Enzyme or Sports Detergent
These detergents break down sweat proteins and eliminate deep odor.
4. Avoid Fabric Softener
Softener coats fibers → traps odor → makes smell worse.
5. Dry Completely
Even slightly damp clothing will smell again. Use airflow or sun-dry.
6. For Hoodies: Treat the Armpits Separately
Hoodie fabrics are thicker, so odor gets trapped more easily.
