Use Supersalt to whiten dull or yellowing whites, brighten colors and blast oxidizable stains like coffee, tea, wine, fruit, grass and blood. Our oxygen brightener works wonders without harsh chlorine bleach. The Celsious laundry care line is plastic-free and certified cruelty-free. As a member of 1% for the Planet we donate one percent of Supersalt sales to environmental nonprofits. We've washed millions of pounds of laundry at our NYC laundromat using non-toxic garment care products, and our customers continue to be impressed by the results. We're excited for you to use this tried-and-true product at home!
