Corewash Laundry Powder


Corewash is your go-to powerhouse for everyday laundry. Our formula is vegan, non-toxic, fragrance-free and biodegradable. It's safe for big and small humans alike, plus it’s safe for the planet!

Unlike laundry pods and strips that contain polyvinyl alcohol (PVA)—a water soluble plastic used for casing—Corewash contains absolutely no plastic. Peer-reviewed studies have concluded that 75% of PVA does not readily biodegrade in US wastewater treatment plants, which means plastic from pods and strips get released into the environment. 

Our laundry powder is PVA-free and contains three simple and effective ingredients. The cardboard and steel canister is recyclable and the labels are fully compostable.

Our line is Leaping Bunny Certified, and as a member of 1% for the Planet we donate one percent of Corewash sales to environmental nonprofits every year.

Pro Tips

You can use Corewash to hand wash delicates by dissolving it in warm water ahead of time.

If you're machine washing and want to put Corewash in the detergent compartment (instead of the drum), check to see that none is left behind. If some gets left behind because your washer is optimized for liquid, dissolve the powder in warm water before adding it to the load.

Corewash comes with a stainless steel spoon (pictured) but you can also use our ceramic mini scoop or any measuring spoon you have at home.

To tackle heavily soiled items, pre-treat with Wunderbar stain stick or Supersalt oxygen brightener before washing with Corewash. To learn more about laundry powder, read our blog post.
