Step-by-Step Removal Guide
1
Blot, never rub
Blot fresh blood with a white cloth or paper towel dampened with cold water. Work from the edge toward the center so the stain does not spread.
Important: Hot water and steam cleaners set blood. Keep everything cold.
2
Dish soap solution
Mix 1 tablespoon of dish soap in 2 cups of cold water. Dab it on with a cloth, wait 5 minutes and blot. Repeat until nothing more transfers to the cloth.
3
Hydrogen peroxide on light carpet
Dab 3% hydrogen peroxide on the stain, let it foam for a few minutes and blot. Test on a hidden area first: it can lighten colored carpet.
4
Enzyme carpet cleaner for dried blood
Scrape off any crust with a spoon, spray an enzyme carpet cleaner, leave it for the time on the label and blot.
Tip: For wool carpet, skip the peroxide and use a wool-safe enzyme cleaner.
5
Rinse and dry
Dab with cold clean water to remove the soap, then press a thick dry towel on the spot with your weight. Let it air dry and vacuum to lift the pile.

Frequently Asked Questions
How do I get dried blood out of carpet?
Scrape off the crust, then use an enzyme carpet cleaner or the dish soap solution, followed by hydrogen peroxide on light carpet. Old stains may need a few rounds.
Will hydrogen peroxide bleach my carpet?
It can lighten colored or dark carpet. Test it on a hidden area and blot it away after a few minutes.
Can I use a steam cleaner on blood?
No. Heat bonds blood proteins to the fibers. Use a cold-water extractor instead.
How do I get blood out of a wool rug?
Use cold water and a wool-safe cleaner only, blot gently, and avoid peroxide and alkaline products. For valuable rugs, call a professional.
What if the stain comes back after drying?
This is called wicking: blood left in the backing rises to the surface as it dries. Treat again, then put a thick towel weighed down on the spot while it dries.
