Vanish Gold is super-boosted and fast-acting. From the ones you can clearly see to the tougher ones that may be hidden deep in the fabric, providing astonishing results in as little as 30 seconds. You choose how to use this versatile stain remover spray; in wash, pre-treat or to soak your fabrics. Do not use on wool, silk, leather, finished or coated surfaces - for example wood and metal.
