Switch to an enzyme-based odor-eliminating detergent

Use a detergent formulated to destroy odors rather than mask them. Products like Hex Performance, WIN Sports Detergent, or sport-specific lines from major brands (such as Tide with odor-eliminating technology) 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 covering up the smell. Standard detergents often fail on synthetic performance fabrics because polyester fibers attract and hold oil-based odors.

Tips

• Follow the product's dosage instructions — more detergent is not more effective
• These detergents cost more per load but can rescue garments you would otherwise discard
• Combine with an oxygen bleach soak for maximum effect on persistent gym odors
