Prewash the item and place it damply in the machine and run a program with normal water quantity of 30-40°C (40°C means darker shade). The fabric colours are optimised for cotton, linen and viscose textiles. Items of the three materials blended with polyester involved receive a brighter colour One capsule lasts 600 g of textile for maximum colouring and up to 1800 g for less intense colouring. Salt does not need to be added, it is already included. If you want to dye a lot at once, you can use up to 5 capsules in one time. However, avoid filling the washing machine in more than half, in the worst case, the result will be tarnish/uneven The colour chart shows colour colour on white - so please note that the colour of the colour will always affect the result. For example, a dark grey or black t-shirt will never turn yellow or orange After dyeing, you should drive two empty washes with detergents to make it clean. Also check rubber mouldings etc and wipe clean Wool, silk, 100% artificial fiber/synthetic materials, items with nylon stitches and fabrics that require dry cleaning should never be dyed
