Dylon All-in-one machine dye is the ideal way to dye your fabrics. Now in an easy to use tin, simply peel off the lid and place in the washing machine to get lasting color on natural fabrics at 40 C. Perfect for reviving faded jeans or brightening up some towels. 1. Put wet tissue into the drum. Remove the cover, peel off the lid and place the tray on the fabric. 2. Full wash cycle (30°C or 40°C). 3. Continue washing (30°C or 40°C) with detergent. Suitable for: cotton, linen and viscose. Blends with synthetic fibres achieve lighter shades (pure synthetic fibres do not dye). One pack dyes 600g of fabric in full color or up to 4 pounds in lighter shades.
