Follow these steps to remove blood stains from acrylic, cotton, linen, nylon, olefin, polyester, spandex or similar fabrics:
- You can usually remove fresh blood stains by a thorough laundering in cold water.
- If any stain remains, soak it in a solution of 1 quart warm water, 1/2 teaspoon dishwashing or liquid laundry detergent, and 1 tablespoon ammonia for 15 minutes.
- Tamp (the method of bringing a brush down with light strokes on stained durable fabrics and materials) or scrape (the method of using a scraping tool to gently lift off excess solid or caked-on stains), blotting occasionally with an absorbent pad.
- Continue as long as the stain lifts. Rinse well with water, making sure to remove all traces of ammonia.
- Then dry or launder.
