Removing dried blood stains at home, especially from fabric, is achievable using the right type of hydrogen peroxide. For stubborn, set-in dried blood stains, salon-grade hydrogen peroxide, also known as 20 volume clear developer, is highly effective.
The Power of Hydrogen Peroxide for Blood Stains
Hydrogen peroxide works by oxidizing the blood, breaking down its pigments and proteins, which makes the stain easier to remove. Its effervescent action helps lift the stain from fabric fibers. While various solutions exist for fresh blood, dried blood requires a more potent approach, which is where 20 volume hydrogen peroxide comes into play.
Selecting the Right Hydrogen Peroxide
The effectiveness of hydrogen peroxide varies depending on its concentration. For blood stains, it's crucial to select the appropriate type based on whether the stain is fresh or dried:
| Peroxide Type | Best Use | Notes |
|---|---|---|
| 3% Medical Grade Hydrogen Peroxide | Fresh, wet blood stains | Commonly found in pharmacies. It works well when the blood is still wet and has not set into the fabric. |
| 20 Volume Clear Developer | Dried, set-in blood stains | This is salon-grade hydrogen peroxide, specifically designed for more robust tasks like lightening hair, and is significantly stronger than the 3% medical grade. It is the recommended choice for removing dried blood stains. |
- Note: While 3% medical grade hydrogen peroxide can work on fresh, wet stains, the 20 volume hydrogen peroxide is generally more powerful for all stages of blood stains, particularly dried ones.
Step-by-Step Guide: Removing Dried Blood Stains with 20 Volume Hydrogen Peroxide
Follow these steps carefully to effectively remove dried blood stains from clothing, sheets, or other fabrics using 20 volume hydrogen peroxide:
- Prepare the Area: Lay the stained item on a clean, flat surface. Place an old towel or a few layers of paper towels underneath the stain to absorb excess liquid and prevent the stain from transferring to the surface below.
- Test on an Inconspicuous Area: Before applying directly to the stain, always test the 20 volume hydrogen peroxide on a small, hidden area of the fabric (e.g., an inside seam) to ensure it doesn't cause discoloration or damage. Wait a few minutes to observe any adverse reactions.
- Apply the Hydrogen Peroxide: Carefully pour a small amount of the 20 volume clear developer directly onto the dried blood stain, ensuring the entire stain is saturated. You should see a bubbling action, which indicates the peroxide is working to break down the blood.
- Allow it to Work: Let the hydrogen peroxide sit on the stain for several minutes. The exact time may vary depending on the age and severity of the stain. For very tough stains, you might need to let it sit a bit longer.
- Blot and Rinse: After the peroxide has had time to work, gently blot the treated area with a clean, damp cloth, working from the outside of the stain inward. Avoid rubbing, as this can spread the stain further. Once the stain appears lifted, thoroughly rinse the area with cold water.
- Repeat if Necessary: For persistent or deeply set dried blood stains, you may need to repeat the application and blotting process multiple times until the stain is completely gone.
- Launder as Usual: Once the stain is removed, wash the item according to its care label, preferably in cold water. Air-dry the item to ensure the stain is fully gone before exposing it to heat from a dryer, which can set any remaining traces of the stain.
Important Considerations & Tips
- Fabric Type: Always exercise caution, especially with delicate fabrics like silk, wool, or heavily dyed materials, as hydrogen peroxide can potentially cause bleaching. Always perform a patch test first.
- Safety: Wear gloves when handling hydrogen peroxide, especially the stronger 20 volume solution, to protect your skin. Ensure good ventilation in the area where you are working.
- Blot, Don't Rub: When cleaning any stain, always blot the area instead of rubbing. Rubbing can push the stain deeper into the fibers or spread it, making it harder to remove.
- Cold Water is Key: Always use cold water when dealing with blood stains. Hot water can cause blood proteins to coagulate and set the stain permanently.
