Rit Color Remover is used primarily to remove or reduce colour from fabric prior to dyeing with Rit Dye. It reduces the colour to an off-white or cream colour, creating a clean, even base colour for dyeing. Color Remover is suitable for use on most washable fabrics, including cotton, linen, rayon, silk, and nylon. It may have a limited effect on polyester, depending upon how it was dyed commercially. Color Remover is a non-chlorine, reductive type of bleach that will not damage or deteriorate washable fabrics as chlorine bleach will. The stovetop method is the most effective at removing colour, maintaining a constant simmer throughout the process. Some fabrics lose their colour in as fast as 10 minutes, others can take an hour or two to achieve a cream colour. Light colour changes, such as brightening or removing stains from white fabrics, can be achieved using Color Remover in a washing machine. Color Remover will not remove the pattern or print from a fabric or the indigo dye from denim.
