Always follow the garment manufacturer's care label instructions. Soak and wash whites and coloured garments separately. Use on washable colourfast fabrics only. Test for colour fastness before using by soaking a hidden part of the garment for at least 60 minutes. If unable to check, do not soak. Some items which are colourfast in a normal wash may run if soaked, even in water alone. Do not soak silk, woollen garments or garments with metal accessories, fasteners and zippers. Do not soak garments with print designs that use metallic inks or coatings. Do not mix with chlorine bleach. 1 level lid = 45g.
