Corewash Laundry Powder


Corewash is your go-to powerhouse for everyday laundry. Our formula is 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 or PVOH)–a water soluble plastic used for casing–Corewash contains absolutely no plastic. A recent peer-reviewed study concluded that 75% of PVA does not readily biodegrade in US wastewater treatment plants, which means plastic is being released into the environment. 

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


Baking Soda (Sodium Bicarbonate), Washing Soda (Sodium Carbonate), Coconut-based Vegetable Soap (Sodium Cocoate, Glycerin, Organic Cocos Nucifera Oil, Water)


Net wt. 32 oz (907g), up to 115 loads


  • Add 1/2 tbsp directly to the drum of a high-efficiency washer
  • Double the dosage for standard washers or extra dirty loads
  • Use on clothing, towels and bedding

Pro Tips

Corewash can be added to your washer's detergent compartment instead of the drum, but check to see that none is left behind. If you find some left behind and/or your washer is optimized for liquid detergent, try dissolving Corewash in a bit of warm water before adding it to your loads.

To tackle heavy stains, pre-treat with our Wunderbar stain stick and Supersalt oxygen brightener!
