Non-chlorine whitener and brightener removes stains by releasing oxygen when activated by water. The released oxygen then penetrates the stain’s molecules and the compromised stain disappears. Has dozens of uses: a laundry pre-soak or booster, a whitener, a carpet spot remover, bathroom grout cleaner; even works on a garage or shop floor. Color-safe and compatible with high-efficiency machines, OxoBrite™ is effective against oil and water-based stains and effective in all temperatures. Its readily biodegradable formula is made using sustainable ingredients. Free of synthetic perfumes and made without dyes; greywater and septic safe.
