The vinegar in your laundry trick? It’s actually inspired by something dry cleaners use: laundry sour! A highly acidic rinse we add at the end of a wash (wet cleaning) to clear out leftover detergent and minerals that can leave clothes stiff. Vinegar (just 5% acetic acid) is a gentler version, probably adapted by a clever dry cleaner for home use. If you’re looking for something stronger than vinegar but safer than sour, products like Downy Rinse & Refresh or Tide Boost use this same science. Ju
