Keeping your clothes' colors vibrant isn't just about aesthetics—it's about extending the life of your wardrobe. Harsh detergents can fade fabrics over time, especially brights and darks. In our lab tests, we evaluated detergents on stain removal, color retention, and cleaning power in cold water, mimicking real-world laundry routines. High-performing options like the Purex 4-in-1 Laundry Detergent scored an overall 8.2/10, shining in color preservation (9/10) while handling dirt, grass, and wine stains effectively.
We prioritized HE-compatible formulas that work in modern machines, deliver at least 140 loads per bottle, and cost under 20¢ per load. Whether you're washing kid's sports gear or favorite tees, these picks prevent bleeding and fading.
Here's how our top contenders stack up based on independent testing for stain removal (out of 100), color retention (Good/Fair/Poor), loads per unit, and price per load.

Our protocol simulated everyday messes: We stained swatches with dirt, blood, grass, body oil, sebum, salad dressing, and red wine, then washed in cold water (40°F) using HE machines. Colors were measured pre- and post-wash with a spectrophotometer for fading percentage. Whites got separate brightness tests. Real-user trials (50+ loads) assessed scent longevity and fabric feel. Purex 4-in-1 topped for balanced performance under $0.20/load.
