Vanish Power O2 Powder
Pre-wash the stain with cold water. Soaking is recommended in this case - dissolve one scoop of Vanish Power O2 Powder in 4L of warm water (max 40°) and soak the stained item. For coloured fabrics, soak for max 1 hour and whites for max 6 hours. Then wash as usual and for best results add one scoop of Vanish to your wash.
Always follow the usage instructions on the Vanish packaging. Do not use on wool, silk or leather. Do not use on finished or coated surfaces - for example wood, metals etc.
