Why Do Tide Pods Stain Laundry?

Since I first began engaged on our information to the greatest laundry detergent again in 2014, I’ve observed a gentle stream of individuals reporting that Tide detergents left everlasting purple stains on their garments. Not too long ago, Becca Laurie wrote for The Define about Tide pods, that candy-like laundry pack, leaving blue stains on her laundry, and the irritating and unsatisfying method that Procter & Gamble, the mum or dad firm of Tide, handled it.

The issue, in response to Tide PR individual Lauren Beene, is that the pod doesn’t dissolve totally within the water, inflicting a whitening agent to deposit in your garments and depart a mark. We adopted up with the corporate on this subject in early 2020, and Procter & Gamble Scientific Communications Supervisor Jennifer Ahoni instructed us that in 2018, Tide modified the composition of its pods “with new movie expertise that higher absorbs water, permitting for higher, extra full dissolution in all washing machines and water circumstances together with chilly water.” Staining has nonetheless been a problem for some folks, nonetheless, and Tide suggests this is because of not inserting the pod within the washer earlier than the garments as really useful, or overstuffing the machine, so there’s not sufficient water to totally dissolve every part that must be dissolved. (“To make sure you aren’t overstuffing your machine,” Ahoni wrote through e-mail, “make sure that your hand suits between your garments and the wall of the drum.”). Nonetheless, in response to Tide, “for the overwhelming majority of shoppers it isn’t an issue,” and the corporate has no plans to take the staining ingredient out.

After we first revealed this put up, we reported that there was a discrepancy between the quantity of detergent washer corporations recommend you utilize (much less), and what Tide recommends (extra)—and theorized that overuse of detergent as really useful by the detergent maker could also be associated to the staining subject. Mary Begovic Johnson, principal scientist at Tide, wrote us to level out that the manuals of many washing machines, together with our choose’s, say to make use of the quantity of detergent prompt on the detergent bottle. Though that is true, the creator of our information to washers and dryers, Liam McCabe, has had conversations with high-level folks at a number of washer corporations who’ve instructed him that two tablespoons of detergent is sufficient for even giant hundreds. Tide recommends utilizing about 5 tablespoons of detergent for a big load (or about 12 kilos, in response to the trade).

Although the precise elements that trigger staining for some folks and never for others stay a thriller, we do know that an excessive amount of detergent could cause different issues: In response to washer corporations and equipment restore folks, an excessive amount of detergent can gunk up your machine, and depart your garments feeling dirty and gross.

Beene instructed us that Tide figures out how a lot detergent to make use of “primarily based off of our intensive testing throughout varied machine fashions and wash circumstances,” and although it’s one thing P&G continues to tweak, the corporate has no present plans to alter its suggestions.
