How to Remove Dried Blood from a Wool Rug: A Surface-Safety Guide

1. Scrape off dried blood. Gently scrape away any dried flakes with a dull knife or spoon. Work from the edges toward the center to avoid spreading. Do not press hard.
2. Blot with cold water. Dampen a clean white cloth with cold water and blot the stain gently. Work from the outside edge toward the center to prevent spreading. Do not rub, as this can damage wool fibers.
3. Apply dish soap solution. Mix a few drops of gentle dish soap with a cup of cold water. Dip a clean cloth into the solution and blot the stain. Let it sit for 5–10 minutes to break down the blood.
4. Blot with cold water again. Use a fresh cloth dampened with cold water to blot away the soap and loosened blood. Change the cloth as it picks up the stain.
5. Repeat if needed. For stubborn stains, repeat steps 3–4. You can also add a tablespoon of white vinegar to the soap solution for extra lifting power. Let the vinegar solution sit for a few minutes before blotting.
6. Rinse and dry. Blot with a cloth dampened with plain cold water to remove any soap residue. Then press with a dry towel to absorb excess moisture. Allow the rug to air dry completely, away from direct heat or sunlight.

Fresh vs. Dried Stains

Fresh blood is easier to remove because it hasn't set. For fresh stains, blot with cold water immediately, then follow the same dish soap method. Dried stains require more patience and repeated blotting. If the stain is very old, you may need to repeat the process several times or consider professional cleaning. For dried stains, you may also want to let the soap solution sit longer (up to 15 minutes) to help break down the protein.

Surface-Specific Precautions

Wool is a natural protein fiber that is sensitive to heat, alkali, and agitation. Always use cold water and gentle products. Test any solution on a hidden area first to ensure it doesn't cause discoloration. Avoid wringing or twisting the rug, as this can distort its shape. Also, avoid using a brush with stiff bristles; if you use a brush, choose one with soft bristles and use light strokes. For wool rugs with a high pile, be extra gentle to avoid matting the fibers.

Common Mistakes to Avoid

• Using hot water. Hot water sets blood stains and can shrink or felt wool.
• Rubbing the stain. Rubbing can damage wool fibers and spread the stain.
• Using bleach or harsh chemicals. These can discolor or weaken wool.
• Using a steam cleaner. The heat and moisture can set the stain and damage the rug.
• Over-wetting the rug. Excess moisture can lead to mold or mildew, especially in wool.
