Best Laundry Detergent: 12 Brands Tested on Stains, Odors, and Color Protection

Introduction

Few household purchases are as confusing as laundry detergent. The claims sound similar, the prices per load vary wildly, and it is hard to know whether a premium bottle actually cleans better than a budget one. So we put twelve popular detergents through a brutal head-to-head comparison to find out which ones genuinely earn their shelf space.

How We Tested

Each detergent was judged on three fronts. First, stain removal: six common stains were applied to white cotton t-shirts, including egg yolk for protein stains, vintage graphite motor oil for oil stains, dark coffee for pigment stains, mustard and tomato sauce for dye-based stains, and soy sauce, which combines protein, oil, and dye in one nasty package. The shirts were left in direct sunlight to dry, since dried stains are far harder to remove, then washed in a top-loader on cold water with a dose sized for badly stained laundry.

Second, odor removal. Shirts were soaked in a fermented mix of cow manure and rotting hay for two days, then treated with gear oil before a hot wash, which is about as hostile as laundry gets. Third, color protection: a red cotton shirt went into every wash to check for fading and stain transfer, and the unstained areas of each white shirt were compared for brightness. Washed shirts also went through a dryer cycle before final judging, because drying can set or reveal stains.

Budget Picks That Punch Above Their Price

Arm & Hammer liquid detergent costs around $14 for 1.3 gallons, works out to roughly 8 cents per load, and is made in the USA. It finished second overall in stain removal, beat out nine more expensive brands on the soy sauce test, placed third on color protection, and came within a hair of the top spot in the final rankings. For the money, it is the standout value in this comparison.

Gain, at $16 for 1.2 gallons with a claimed 154 loads (about 10 cents per load) and made in Canada, finished fourth overall with an average rating of 3.7. It took second place on the mustard stain, third on color protection, and third on the gear oil odor test, which is impressive for a budget bottle.

Amazon Basics detergent costs $17 for 82.5 oz with a claimed 110 loads at 15 cents per load, made in the USA. It consistently landed near the top: fifth on the oil stain, second on soy sauce, fourth on keeping the white fabric bright, and fifth on color protection. Only mustard was a weak spot, where it finished last.

Plant-Based and Gentle Options

Biokleen is a concentrated, plant-based formula at $35 for 1.2 gallons, claimed 300 loads (12 cents per load), made in the USA. Its results were disappointing: it barely edged out plain water on the oil stain, turned the shirt gray on the mustard and soy sauce tests due to stain transfer, and finished near the bottom on odor removal.

Ecos, a 100% vegan plant-powered detergent made in the USA, costs $27 for 200 oz across two containers, good for a claimed 200 loads at 14 cents per load. It outperformed Biokleen but still trailed the leading conventional detergents, finishing tenth on the oil stain, twelfth on soy sauce, and last on the gear oil test with a dark, smelly stain left behind.

Molly’s Suds laundry powder, at $38 for two packages with a claimed 240 loads (16 cents per load), advertises safer ingredients and a simple five-ingredient formula made in the USA. It struggled badly with the graphite and oil stain, finishing last there and smelling strongly of the oil afterward, though it did fare better on mustard with a fourth-place finish.

Seventh Generation, $15 for 40 oz with a triple enzyme formula and 53 loads (28 cents per load), made in the USA, is more concentrated than most rivals. That concentration did not translate to results: eleventh on the oil stain, ninth on color protection, and a mid-pack tie on soy sauce.

All Free & Clear, at $22 for 82.5 oz with double the concentration and a claimed 110 loads, made in the USA, performed solidly. It beat Molly’s Suds on the oil stain, won the soy sauce test outright, placed fourth on the gear oil odor test, and finished mid-pack on color protection.

Tyler Glamorous Wash is a different animal: $21 for 16 oz, good for just six loads at roughly $3.50 per load, made in Tyler, Texas. It is marketed for linens, lingerie, and fine fabrics with a soothing aroma rather than stain claims, and it smells like a perfume factory. It performed decently on mustard with a third-place finish, but finished twelfth on the oil stain and ninth on gear oil, where the perfume at least masked the smell. As a luxury scent wash it has appeal, but it is not a value pick for everyday laundry.

The Big Names: Tide, Tide Pods, and Persil

Tide liquid, at $15 for 84 oz with a claimed 64 loads (23 cents per load) and made in Canada, was the overall winner with an average rating of three. It took first place on the graphite and oil stain, mustard, and gear oil, and the Tide shirt smelled perfectly clean after the odor test. Its aggressive stain attacking did cost it some points on whiteness, finishing sixth on color protection.

Tide Pods, $28 for 112 loads at 25 cents per load and made in Canada, are designed for cold water, stain removal, and color protection. They cleaned just as well as or better than regular Tide liquid, finished third on the oil stain, second on color protection, and fifth on soy sauce. The convenience is real, and the cleaning performance backs it up.

Persil ProClean, $24 for 82.5 oz with cold-water stain fighting and odor elimination technology, made in Canada, shone brightest on color protection, where it finished first in both whiteness and color tests. On pure stain removal, however, it trailed Tide, placing ninth on the oil stain and second on gear oil.

Odor Test Highlights

The fermented manure and gear oil wash separated the field dramatically. Tide removed the stain almost entirely and left no oil smell. Arm & Hammer made strong progress, and Gain performed well for a budget detergent in third. Persil took second on gear oil. At the other end, Ecos, Biokleen, and Seventh Generation all left dark, smelly stains behind, confirming that plant-based does not automatically mean odor-fighting power.

Final Rankings and Buying Advice

Based on average finish across every test, Tide liquid came out on top, followed closely by Arm & Hammer, then Gain. That result tells a clear story: the best-performing detergents span the whole price range, and paying more does not guarantee cleaner clothes.

If you want the best all-around cleaner and do not mind paying about 23 cents per load, Tide is the safe pick. If value matters most, Arm & Hammer at roughly 8 cents per load performed almost as well and is the smartest spend in the lineup. For color protection specifically, Persil ProClean was the clear winner, and Tide Pods are the most convenient option that still cleans like the category leader.

Conclusion

Twelve detergents, three brutal tests, and one reassuring conclusion: you do not need the most expensive bottle on the shelf. Tide earned the top spot on raw performance, but Arm & Hammer delivered nearly identical results at a fraction of the price per load, and Gain and Amazon Basics proved that budget does not have to mean compromise. Match the detergent to what you actually care about, whether that is stain power, odor removal, color care, or cost, and you will wash smarter without overspending.
