The Trio


We've used a combination of our laundry powder, oxygen brightener and soap stick to stain treat and wash thousands of pounds of laundry at our Brooklyn laundromat, and that's how we know The Trio really works.

Corewash is your go-to powerhouse for everyday laundry. It's safe for big and small humans alike, plus it’s safe for the planet! Use our laundry powder with our Wunderbar soap stick and Supersalt color-safe oxygen brightener to treat heavy stains.

Non-toxic, fragrance-free and biodegradable


  • Corewash - Washing soda, baking soda and vegetable soap
  • Supersalt - Sodium percarbonate and washing soda (no chlorine bleach!)
  • Wunderbar - Vegetable soap
