Fabric Magic Colour run remover 12 sheets Avoids colour runs in mixed washes. The new colour run remover sheets from Fabric Magic are the quick and easy way to avoid colour runs in your washing. Each sheet is specially treated to help prevent transfer of colour from one garment to another. The sheets are ideal for use in wash loads containing dark or bright coloured items, quickly absorbing any loose dye released during washing. This allows you to wash with the assurance that they will stay bright and not discolour.
