In plain English: Only non-chlorine (oxygen-based, “color-safe”) bleach is allowed. Regular chlorine bleach will damage the fabric or the dye.
What it looks like on the tagA triangle outline with two diagonal lines inside it, running parallel to the left edge. US labels often add “only non-chlorine bleach, when needed.”
What to do
- Use an oxygen bleach — sodium percarbonate products like OxiClean count.
- Add it with your detergent for brightening, or pre-soak for stains.
- Skip anything labeled chlorine, hypochlorite, or simply “bleach.”
What happens if you ignore it
Chlorine bleach strips dyes unevenly, yellows some synthetics and wool, and weakens spandex. The damage is chemical and permanent.
Where you'll see it
Colored cottons, blends, activewear, and most printed fabrics.
