Step-by-Step Guide to Removing Blood Stains from Carpets

Removing blood stains from carpets requires prompt action and the right approach to prevent the stains from setting. Here’s a concise, actionable guide to effectively clean blood out of your carpet, ensuring you tackle both fresh and dried stains with confidence.

1. Blot the Stain

Immediately blot the stain with a clean, dry cloth or paper towel. Press down firmly to absorb as much blood as possible, but avoid rubbing, which can spread the stain.

2. Prepare a Cleaning Solution

Mix a solution of cold water and a mild detergent (1 tablespoon of dish soap in 2 cups of cold water). Cold water is essential as warm water can set the stain.

3. Apply the Solution

Dab the solution onto the stain using a clean cloth. Work from the outside in to prevent spreading the stain. Gently blot to apply the solution, but do not rub.

4. Rinse and Blot

Rinse the area by dabbing with a cloth moistened with cold water, then blot with a dry cloth. Repeat this process to ensure all detergent is removed from the carpet.

5. Tackle Tough Stains with Hydrogen Peroxide

For dried or tough stains, apply a mixture of hydrogen peroxide (3%) and a drop of dish soap. Hydrogen peroxide acts as a mild bleach, so test it on a small, inconspicuous area first.

Apply the mixture to the stain and let it sit for a few minutes.

Blot away with a clean cloth until the stain lifts.

6. Final Rinse and Dry

Rinse the area again with cold water and blot dry. Use a clean section of the cloth each time to avoid re-depositing the stain.

7. Air Dry

Let the carpet air dry completely. Avoid walking in the area until it’s fully dry. You can speed up the drying process with a fan if necessary.

8. Vacuum

Vacuum the cleaned area to restore the carpet’s texture after it has dried completely.

Additional Tips:

Act quickly: The sooner you address the stain, the easier it will be to remove.

Always perform a patch test when using hydrogen peroxide or any new cleaning solution to ensure it doesn’t damage or bleach your carpet.

If the stain persists, consider consulting a professional carpet cleaner, especially for expensive or delicate carpets.

Following this guide should help you effectively remove blood stains from your carpet, preserving its appearance and extending its life.

1. Acting Quickly: The First Line of Defense

When it comes to blood stains on carpets, speed is of the essence. Acting quickly can mean the difference between an easily manageable clean-up and a stubborn stain that refuses to budge. The moment a spill occurs, the clock starts ticking, and the faster you respond, the less time the blood has to seep into the carpet fibers and set. Here’s why swift action is crucial and how to do it right.

Why Quick Action is Crucial

Prevents Setting: Blood begins to thicken and bind with carpet fibers as it dries, making it significantly harder to remove once it sets.

Eases Cleaning: Tackling the stain before it dries means you’ll likely need less effort and fewer cleaning products to remove it.

Correct Blotting Technique

Absorb the Moisture: Use a clean, white cloth or paper towel to blot the stained area gently. This method helps to absorb as much blood as possible without pressing it further into the carpet.

Avoid Rubbing: Rubbing the stain can not only spread the blood but also work it deeper into the carpet fibers, increasing the risk of a permanent stain.

Work from the Outside In: Start blotting from the edges of the stain and move towards the center. This technique prevents the stain from spreading outward.

Choosing the Right Materials for Blotting

Use Clean White Cloths or Paper Towels: White materials are preferred for blotting because they don’t risk transferring dyes onto the carpet, which could make the situation worse. Additionally, their high absorbency effectively soaks up moisture.

Folded vs. Flat: Folding the cloth or paper towel provides multiple layers of absorbency and allows you to switch to a clean section easily as you blot up the blood.

By understanding the importance of acting quickly and employing the correct blotting technique, you can effectively prevent a blood stain from becoming a permanent fixture on your carpet. Remember, the initial response to a spill plays a pivotal role in the overall ease and success of the stain removal process.

2. Cold Water Rinse and Blot

After the initial blotting, the next crucial step in removing blood stains from carpets involves a cold water rinse and subsequent blotting. This method helps to dilute and further remove any remaining blood, preventing it from setting into the carpet fibers. Here’s a detailed look at how to effectively carry out this process.

Why Cold Water?

Prevents Setting: Cold water helps prevent the blood from coagulating, which makes it easier to rinse out the carpet fibers. Warm or hot water, conversely, might set the stain, making it harder to remove.

Dilutes the Stain: Rinsing with cold water dilutes the remaining blood, reducing its concentration and making it easier to blot away.

Step-by-Step Cold Water Rinse and Blot Method

Rinse with Cold Water:

Gently pour cold water directly onto the stained area to help dilute the blood. For smaller stains or delicate carpets, consider using a spray bottle to control the amount of water applied.

Gentle Blotting:

Use a clean, dry cloth or paper towel to blot the area gently. The goal here is to absorb the diluted blood without pressing the stain deeper into the carpet fibers.

Repeat as Necessary:

Continue to rinse the area with cold water and then blot gently. With each rinse and blot, you should see less and less blood transferring onto your cloth.

Avoid Rubbing or Scrubbing:

It’s crucial to blot gently without rubbing or scrubbing the stain, as these actions can work the blood deeper into the carpet and potentially damage the fibers.

Evaluate the Stain:

After several cycles of rinsing and blotting, if the stain is still visible, you may need to move on to a cleaning solution for further treatment. However, many fresh stains will significantly lighten or completely disappear with just this method.

Final Steps

Air Dry:

Once the stain is no longer transferring onto your blotting cloth, allow the carpet to air dry completely. You can expedite the drying process by using a fan or a dry, absorbent towel to blot the wet area.


After the carpet has dried, vacuum over the treated area to restore the texture of the carpet fibers.

This cold water rinse and blot technique is a simple yet effective way to tackle blood stains, significantly reducing or completely removing them before they are set. Patience and repetition are key—as long as you’re seeing improvement, keep rinsing and blotting.

3. Applying Potato Starch or Cornstarch

After addressing the initial stain with cold water and blotting techniques, employing potato starch or cornstarch can offer an innovative approach to further lifting the blood stain from your carpet. These natural powders act as absorbents, drawing out moisture and remaining blood particles from the fibers. This step is particularly useful for stubborn or slightly damp stains that need extra attention.

How Starch Helps in Blood Stain Removal

Absorbency: Both potato starch and cornstarch have high absorbency properties, which help them draw out moisture and residual blood from the carpet fibers.

Safe for Carpets: These natural substances are gentle on carpet fibers, reducing the risk of damage or discoloration.

Step-by-Step Guide to Using Starch

Sprinkle the Starch:

Generously sprinkle potato starch or cornstarch over the entire stained area. Ensure the stain is completely covered with a thin layer of starch.

Let It Sit:

Allow the starch to sit on the blood stain for at least 30 minutes. For deeper stains or if the area is still moist, leaving it for a few hours or even overnight can be more effective.

Gently Work the Starch:

With your fingers or a soft brush, gently work the starch into the top layer of the carpet fibers. This action helps the starch reach deeper into the stain without damaging the carpet.

Vacuum the Area:

After allowing sufficient time for the starch to absorb the stain, use a vacuum cleaner to remove the dried starch from the carpet. The vacuum will also help lift any loosened particles of the blood stain.

Inspect and Repeat if Necessary:

Check the area to see if the blood stain has been lifted. If a shadow of the stain remains, you can repeat the process with fresh starch.

Final Considerations

Vacuum Thoroughly: Ensure all starch is completely vacuumed up to prevent any residue from attracting more dirt to the area.

Spot Test: Although potato starch and cornstarch are generally safe for carpets, conducting a spot test in an inconspicuous area can prevent unexpected reactions, especially on delicate or colored carpets.

Using potato starch or cornstarch is an effective, eco-friendly method for tackling lingering blood stains on carpets. This technique, combined with prompt action and proper cleaning steps, can significantly enhance your chances of restoring your carpet to its original condition.
