Persil laundry detergents first appeared in U.S. stores in 2015, and soon thereafter this import from Europe cleaned up in Consumer Reports’ tests, taking Tide down a notch. A commercial during Super Bowl 50 followed, touting the top-rated Persil ProClean Power-Liquid 2in1, and you can imagine the post-game analysis at Procter & Gamble, maker of Tide. Both manufacturers reformulated their detergents this year, and Consumer Reports put them to the test. Tide Plus Ultra Stain Release is back on top, by a statistically insignificant thread.

Both Tide Plus Ultra Stain Release and Persil ProClean Power-Liquid 2in1 were excellent, earning the same overall score that's high enough to make them recommended. Both liquid detergents were the best tested at removing body oil, dirt, and grass stains, and they even removed more of the blood, chocolate, wine, and tea stains than other detergents in our tests. Tide and Persil performed so similarly that you won't see a difference in cleaning, and both stand out from the more than 50 other detergents tested. Here’s a look at both:

Tide Plus Ultra Stain Release 
Price per load:
 25 cents
Use in: The HE formula is meant for front-loaders and high-efficiency top-loaders, and it's the detergent we tested because those machines outsell agitator washers. There is also a formula for standard agitator top-loaders. Most detergents now sold can be used in any washer type. Detergents meant solely for agitator machines have been disappearing from store shelves for years and no longer appear in our laundry detergent ratings.
Heads-up: Check for coupons online. And when doing laundry be sure to read the label’s recommended dose for your load size. As washer capacities have increased, P&G's dosing caps changed from three lines to five bars. 

Persil ProClean Power-Liquid 2in1
Price per load:
 25 cents
Use in: Any type of washer
Heads-up: When Persil was first sold in the U.S. it was available only at Walmart, but now you’ll find it at many retailers, including Target and Amazon. Check Persil’s site for coupons. Note that the manufacturer offers a money-back guarantee if you don’t love its detergent. It doesn't define “love,” so we’ll leave that to you.

For a look at the best and worst detergents, see our laundry detergent ratings. We've improved our ratings, giving you more information to help you choose. Most of the detergents we test are liquid, the big sellers, as sales of powders dissolve. The convenience of liquid detergent pods, or pacs, has helped to boost their popularity despite the fact that none cleaned as well as the best liquids and the fact that many pacs cost more per load. Consumer Reports continues to urge households where children younger than 6 spend time to not use liquid detergent pacs until safety measures lead to a meaningful drop in injuries.

Scent helps drives the purchase of laundry detergent, and a quarter of the folks surveyed said many scents are too strong, according to Mintel, a market research company. Of course, you can buy scent-free varieties. You know what you like. Post user reviews to let other readers know what you think.
