How to Remove Blood from Carpet

Blood stains on carpet can look alarming, but they're very treatable — especially when fresh. The most important rule: always use cold water, never hot. Heat causes blood proteins to coagulate and bond permanently to carpet fibers, making the stain nearly impossible to remove. Act fast and follow these steps.

What You'll Need

Cold water (never warm or hot)
3% hydrogen peroxide (available at any pharmacy)
FOLEX Instant Carpet Spot Remover (32 oz)
Nutricost Baking Soda (2 LBS) – for deodorizing if needed
HOMEXCEL Microfiber Cleaning Cloths (Pack of 12)
Empty Spray Bottles (16oz, 2-Pack)
Dish soap (clear, a few drops)

Method 1: Cold Water and Dish Soap (Fresh Blood)

Step 1: Blot Immediately

Using a clean white microfiber cloth, blot the blood stain immediately to absorb as much as possible. Press firmly and lift — never rub. Use a white cloth so you can see how much blood is transferring.

Step 2: Apply Cold Water

Fill a spray bottle with cold water and spray the stained area lightly. Blot again with a fresh cloth. Repeat several times, working from the outside of the stain inward.

Step 3: Apply Dish Soap Solution

Mix 1 teaspoon of clear dish soap with 1 cup of cold water. Apply to the stain and let it sit for 5 minutes. Blot firmly with a clean cloth. The soap helps lift the blood proteins from the fibers.

Step 4: Rinse and Blot

Spray clean cold water over the area to rinse out the soap. Blot thoroughly until no more color transfers and the area is as dry as possible.

Method 2: Hydrogen Peroxide (Stubborn or Dried Blood)

Hydrogen peroxide is highly effective on blood stains because it reacts with the iron in blood, breaking down the proteins. Use 3% hydrogen peroxide — the standard pharmacy concentration.

Step 1: Test First

Always test hydrogen peroxide on a hidden area of the carpet first. It can lighten some carpet colors, especially darker shades. If the carpet color is unaffected after a few minutes, proceed.

Step 2: Apply Hydrogen Peroxide

Pour or spray a small amount of hydrogen peroxide directly onto the blood stain. You'll see it fizz — that's the reaction breaking down the blood. Let it sit for 5–10 minutes.

Step 3: Blot and Rinse

Blot the area firmly with a clean white cloth. Rinse with cold water and blot again. Repeat if necessary until the stain is gone.

Method 3: FOLEX Spot Remover (Any Blood Stain)

FOLEX Instant Carpet Spot Remover is one of the most effective commercial options for blood stains. Apply it directly to the stain, work it in gently with your fingers, and blot with a clean cloth. No rinsing required. Repeat as needed.

Removing Dried Blood from Carpet

Gently scrape away any dried, crusted blood with a dull knife or spoon.
Rehydrate the stain with cold water and let it sit for a few minutes.
Apply hydrogen peroxide or FOLEX and let it dwell for 10 minutes.
Blot firmly and repeat until the stain lifts.
Rinse with cold water and blot dry.

Critical Rules for Blood Stain Removal

Always use cold water — hot water permanently sets blood stains.
Never rub — always blot to avoid spreading and fiber damage.
Act fast — fresh blood is dramatically easier to remove than dried blood.
Test hydrogen peroxide on a hidden area before applying to visible carpet.

Final Thoughts

Blood stains respond well to cold water, dish soap, and hydrogen peroxide when treated promptly. For stubborn or dried stains, FOLEX is an excellent commercial option. The key is always cold water and blotting — never hot water or rubbing.
