If the stain is still fresh (wet)
For blood stains, blot any excess. Mix 1/4 – 1/2 tsp OxyMagic with warm water (40 º – 60 º C). Soak clothes for 15-30 minutes. Rub and wash with detergent as usual.

If the stain has already dried
Rinse the blood stain under cold, running water or soak it in cold water for at least 15 minutes. Then pre-treat the stain with OxyMagic by rubbing in to fully penetrate the stain. Wait 15-30 minutes then launder your item with detergent in the warmest water recommended on the garment label.
