Remove or reduce existing fabric colour, giving you a dye ready canvas for spectacular results and true colour. Perfect for dye projects where you want to completely change the colour of the fabric or as a pre treatment for faded, discoloured and stained fabric. Removes dye stains (washed by mistake with coloured items) and food stains (such as fruit juice, ketchup and tea) from whites. Unlike traditional bleach, which contains chlorine that can damage fabric, Rit Colour Remover is chlorine free so that you can safely dye fabric after removing its colour. Works best on cotton, linen, wool, rayon and ramie.
