Persil was one of the most effective stain removers in our testing, and it even bested our main pick on several stains. But its strong, lingering fragrance is not for everyone.

Consumer Reports

CR’s take: Persil ProClean Stain Fighter, when used to pretreat stains, is also better than most of the stain removers we test. With just 5 minutes of soaking, Persil lifts common stains like body oil and dirt, and takes on chocolate ice cream. Not in a rush? Persil can remove salad dressing and gravy, if you let it soak in overnight (though a longer soak didn't help this detergent get rid of stains from black coffee, cherry juice, or used motor oil). And when it's time to wash your clothes, know that Persil is one of only two detergents that earn a Very Good rating in removing tougher stains such as red wine, chocolate, blood, and tea.

This detergent, sold under Costco’s house brand, was better at removing stains than many more-expensive detergents, and it is also good at getting rid of odors.
