Dylon Wash and Dye is the easy way to revive or change the colour of your fabrics. It gives strong, permanent colour to natural fabrics in just two 40 degree C cycles in the washing machine. Wash and Dye is the simple solution to restore the colour of faded fabrics. Cotton, linen and viscose will dye to the full shade. Polyester/cotton and polyester/viscose mixtures will dye to lighter shades. Wool, silk, polyester, nylon, acrylic and fabric with special finishes e.g. dry clean only cannot be dyed. Up to 500g of fabric (e.g. approximately 1 large pair of jeans) will dye to the full shade. A maximum of 1 kg can be dyed to lighter shades. Colour mixing rules apply, e.g. brown dye on orange fabric will give terracotta. Patterned fabric will often still show through.
