Switch to an enzyme-based odor-eliminating detergent

Use a detergent specifically formulated to destroy odors, such as Tide Sport, Hex Performance, or WIN Sports Detergent. These products target the organic compounds that cause persistent smells, especially in synthetic athletic fabrics.

Why It Works

Odor-eliminating detergents contain specialized enzymes (protease and lipase) at higher concentrations than standard formulas. These enzymes break down the sweat proteins and body oils that bacteria feed on, eliminating the food source rather than just masking the smell. Some also include cyclodextrin molecules that trap odor compounds.

Tips

• Standard detergents often fail on synthetic performance fabrics because polyester fibers attract and hold oil-based odors
• These detergents cost more per load but can save garments you would otherwise discard
• Follow the product's dosage instructions — more is not better
• Combine with an oxygen bleach soak for maximum effect on persistent gym odors
