What Is the Difference Between “Chlorine Bleach” and “Non-Chlorine Bleach”?
“Chlorine bleach” uses sodium hypochlorite as the active ingredient.
When selecting which type of bleach to use, always check the fabric care label for fiber content and wash instructions. Chlorine bleach is not recommended for some fabrics like spandex, wool, silk, mohair or leather.
“Non-chlorine bleach” uses hydrogen peroxide as the active ingredient.
If in doubt about whether to use bleach, you can do a quick bleachability test. Make a solution of 2 teaspoons (10 ml) of Clorox® Bleach or Clorox® Scented Bleach and 1/3 cup of water. Apply a drop of this solution on a hidden area of the fabric. Rinse after 5 minutes and dry. If there is no color loss, you can safely use the bleach tested.
