Removing Period Stains from Washable Fibers
If you need to remove period stains from washable fibers such as cotton, nylon, polyester, or spandex, it is important to follow these steps.
1. Work immediately to remove the fresh period stains by laundering them as usual in cold water.
2. If the items are still stained after a cold water cycle, then you should soak them.
3. Mix one quart of warm water with one tablespoon of ammonia and one half teaspoon of dishwashing detergent.
4. Place the stained items in the mixture and allow it to sit for fifteen minutes.
Once this is done you should tamp or scrape the stained materials. To tamp it you should bring a brush down on top of fabric with light strokes.
To scrape it, you should use a scraping tool and gently lift any excess stains or caked-stains from the material. As you do this, be sure to occasionally blot the stained material with an absorbent pad dampened with a pre-stain treatment.
You should continue to do this until the stain as been removed. After this, rinse it with water to remove any of the remaining ammonia.
You can dry the materials and launder them as usual once the stain as been completely removed, but be cautious not to place it in the dryer until it is completely removed.
