Dissolve 1/4 – 1/2 tsp OxyMagic with 100-150 ml of warm water in a small spray bottle. Spray directly to the stain and wait 15-30 minutes. Rub and launder your item with detergent in the warmest water recommended on the garment label.
If the stain has set-in, leave in OxyMagic for 1-6 hours before washing your item. If some stain remains treat again with OxyMagic and re-launder. Or if the garment is bleach-able, you may re-launder with bleach and detergent.
