How to Remove Blood Stains from Carpet the Right Way

Blood on the carpet can be alarming, but a fresh blood stain doesn’t always mean the carpet is ruined. The key is knowing what to do — and what not to do — before the stain has a chance to set.

Blood is a protein-based stain, which means heat can make the problem worse. If you discover blood on your carpet, resist the temptation to reach for hot water or start scrubbing. A careful approach can make a significant difference.

Start With Cold Water

If the blood is still fresh, begin by gently blotting the area with a clean, white absorbent cloth. Do not rub or scrub. Rubbing can push the blood deeper into the carpet fibers and spread the stain.  For a refresher on the proper technique, see our guide on how to blot a carpet stain correctly.

Next, lightly dampen a clean white cloth with cold water and blot the stained area. Work from the outside of the stain toward the center to help prevent it from spreading.

Continue blotting with clean sections of the cloth as the blood transfers from the carpet. You may need to repeat the process several times.

For additional guidance, the Carpet and Rug Institute’s blood stain removal recommendations provide a helpful reference for treating small blood spots on carpet.

What Not to Do

One of the biggest mistakes when treating blood on carpet is using heat.

Avoid:

  • Hot or warm water
  • Steam
  • Hair dryers or other heat sources
  • Aggressive scrubbing
  • Colored towels that could transfer dye to the carpet
  • Using large amounts of cleaning solution

Heat can cause protein-based stains such as blood to become more difficult to remove. Excessive moisture can also allow a spot to travel deeper into the carpet backing or cause it to wick back after drying.

A Simple Approach for Small, Fresh Spots

For a small amount of blood on a synthetic carpet, start with cold water and careful blotting. If some discoloration remains, a small amount of mild dish soap diluted with water may help.

Apply the solution sparingly to a clean white cloth rather than soaking the carpet. Gently blot the area, working from the outside toward the center. Follow with a small amount of clean water to remove cleaning residue, then blot the area as dry as possible.

Always test any cleaning solution in an inconspicuous area first. Carpet fibers, dyes and finishes can react differently to cleaning products.

Pro Tip: Don’t Reach for the Strongest Cleaner First

Our pro tip: With blood stains, more cleaning product isn’t necessarily better.

The goal is to remove the blood without damaging the carpet fiber or leaving behind a sticky residue that attracts soil. Professional carpet cleaners identify the type of fiber and the nature of the stain before choosing the appropriate cleaning chemistry.

If you’re unsure what product is safe for your carpet, it’s better to stop than to experiment with multiple household cleaners. An unsuccessful DIY attempt can sometimes make professional stain removal more difficult.

When Should You Call a Professional?

A small, fresh spot can often be addressed at home, but there are situations where professional carpet cleaning is the better choice.

Consider calling a professional when:

  • The blood stain is large or extensive.
  • The blood has dried into the carpet.
  • The stain has penetrated into the carpet backing or padding.
  • You’ve already tried several cleaning products without success.
  • The carpet is wool or another delicate natural fiber.
  • You’re concerned about discoloration or damage to the carpet.
  • The blood is associated with a larger bodily-fluid spill.

Blood and other bodily fluids can require special cleaning and handling procedures, particularly when the amount is more than a small household spot. The IICRC notes that larger blood spills may require a technician with specialized training.

Professional Carpet Cleaning Can Make the Difference

When a blood stain doesn’t respond to careful spot cleaning, don’t keep adding products and scrubbing. Professional carpet cleaners have specialized stain-removal chemistry, equipment and experience to determine the safest approach for the carpet.

At Carter’s Carpet Restoration, our experienced technicians understand that not every stain should be treated the same way. The right cleaning method depends on the type of carpet fiber, the age of the stain and how deeply the substance has penetrated the carpet.

If you’ve tried to remove a blood stain and it’s still visible, let the professionals take a look before the stain becomes a bigger problem.
