Unfortunately, we do not sell a white dye. However, if the garment you are wanting to dye is a natural fabric (such as cotton, linen, silk, wool or ramie), then you can remove the black color using Rit Color Remover. This will bring the garment to a white or off-white color. Then, launder it with Rit Whitener Brightener to lighten the color. Unfortunately, if your garment has more than 35% synthetic material (such as polyester, acrylic or acetate), then you cannot remove or whiten the color on the garment.
