RIT All Purpose Liquid Dye helps refresh, recolour or customize washable fabrics made with natural fibres such as cotton, linen, wool and silk, and also works on nylon and rayon. The 236 mL (8 oz) liquid format is easy to measure for sink, bucket, stovetop or washing machine dye projects. Use with clean fabric, follow the package directions and test first when dyeing blends or finished items.
