Choose a detergent formulated for whites

Use a detergent designed for whites or one containing oxygen bleach or optical brighteners. Products like Tide Plus Bleach Alternative, Persil ProClean, or Seventh Generation Free & Clear with OxiBoost are formulated to maintain brightness.

Why It Works

Whites-specific detergents contain enzymes that break down protein-based stains (sweat, food), optical brighteners that absorb UV light and re-emit blue-white light, and sometimes oxygen bleach to oxidize yellowing compounds. These ingredients counteract the gradual dulling that occurs with regular washing.

Tips

• Optical brighteners make whites appear brighter under UV light but are purely cosmetic
• Enzyme-based detergents work best in warm or hot water
• Avoid using too much detergent — residue itself causes graying over time
