The tiny triangle on your clothing labels has a surprising meaning — and most people have no idea

The triangle on a clothing care label indicates whether bleach can be used: a plain triangle means bleaching is allowed, while a triangle crossed out with an X means it should be avoided. Understanding the symbol can help prevent clothes from being permanently damaged by chlorine bleach.

The article also explains washing machine cycle symbols. A tub with no lines means normal washing, one line means permanent press, and two lines mean delicate or gentle; these cycles suit different fabrics and levels of wear. Labels marked “dry clean only” or “hand-wash only” also signal that a garment should not go through a standard machine cycle.
