The Vanish Oxi Advance Crystal White formula, gives whiter whites even after 50 washes. The multi power formula maintains your whites, removes stains and eliminates odours whilst giving your laundry a hygiene boost in-wash. Always follow washing instructions on garment or fabric label. Check for colour fastness by testing a hidden area of the fabric. Rinse and allow to dry. Reclose lid after each use and keep Vanish in a cool dry place. For best results, it may be necessary to repeat parts of the process. Do not use on any garment or rug made of wool, silk or leather. Do not use on finished or coated surfaces - for example wood, metals etc. Do not soak fabrics with metal fasteners or flame-resistant finishes. Do not expose pre-treated or soaked garments to sources of direct heat or direct sunlight before washing or rinsing thoroughly. Do not contaminate the product in the tub. Once mixed, do not leave solution in a sealed container. It will continue to give off oxygen and the container may build up pressure and leak.
