How to Remove Blood from Carpet

Blood on Carpet: Don't Panic

Carpet fibers trap stains quickly, but blood can absolutely be removed — especially if you act fast. The golden rule: cold water only, and blot don't rub. Here's the full step-by-step method.

What You'll Need

Step-by-Step: Fresh Blood on Carpet

Blot immediately. Use a clean microfiber cloth to absorb as much blood as possible. Press firmly and lift straight up — never rub sideways or you'll spread the stain and push it deeper into the fibers.
Apply cold water. Dampen the area lightly with cold water and blot again. Repeat until no more blood transfers to the cloth.
Spray carpet stain remover. Apply Carpet Spot Remover directly to the stain. Let it sit for 5 minutes.
Blot from outside in. Work from the edges of the stain toward the center to prevent spreading.
Rinse with cold water and blot dry. Repeat if needed.
Sprinkle baking soda over the damp area to absorb moisture and odor. Leave for 30 minutes, then vacuum.

Step-by-Step: Dried Blood on Carpet

Scrape up any dried crust gently with a spoon or dull knife.
Dampen with cold water to rehydrate the stain. Let it sit for 5 minutes.
Apply Carbona Stain Devils. Carbona Liquid Stain Devils is enzyme-based and breaks down dried blood proteins effectively. Let sit 10–15 minutes.
Blot thoroughly with a clean microfiber cloth.
Follow with hydrogen peroxide for stubborn stains. Apply hydrogen peroxide, let fizz, then blot. Test on a hidden area first for colored carpets.
Rinse and dry. Blot with a damp cloth to remove residue, then sprinkle baking soda and vacuum once dry.

What NOT to Do on Carpet

❌ Don't rub — it spreads the stain and damages carpet fibers
❌ Don't use hot water — it sets blood stains permanently
❌ Don't over-wet the carpet — excess moisture can cause mold under the padding
❌ Don't use chlorine bleach on colored carpet
