What is bleach color spread?

Bleach color spread refers to the way in which bleach affects the color of fabrics. When bleach is applied to a fabric, it can spread beyond the intended area and can cause discoloration or fading. The amount of color spread will depend on a number of factors, including the type of fabric, the concentration of bleach used, and the length of time the bleach is left on the fabric. For example, bleach may spread more easily and quickly on fabrics made of natural fibers such as cotton, linen, and wool, compared to synthetic fibers such as polyester and rayon. Additionally, fabrics that are already light in color will tend to show more visible color spread than darker fabrics. It is important to follow manufacturer's instructions when using bleach on fabrics and to test a small, inconspicuous area first to prevent unwanted color spread.
