← Stain and Surface GuideBlood Stain Removal Guide
Blood is a protein-based stain, which means hot water is the enemy. Heat cooks the proteins into the fibers, so always start with cold water and treat it as soon as you notice it.

Clothing
- Rinse the stained area under cold running water immediately, working the fabric with your fingers to loosen the stain.
- For a dried stain, soak the garment in cold water with a scoop of enzyme-based laundry booster for at least 30 minutes.
- Apply a liquid stain remover directly to the spot and gently rub the fabric together before washing.
- Wash in cold water on the normal cycle, then check the spot before putting the garment in the dryer.
Safety note: Never use hot water or place a bloodstained item in the dryer until you have confirmed the stain is completely gone, since heat will set it permanently.
Mattress
- Blot the stain with a cloth dampened in cold water, pressing rather than rubbing to lift the blood without pushing it deeper.
- Make a paste of cold water and a small amount of enzyme cleaner, apply it to the stain, and let it sit for 5 to 10 minutes.
- Blot again with a clean, cold, damp cloth until the stain lifts, repeating as needed.
- Once the stain is gone, blot the area dry and let it air out fully before putting sheets back on.
Safety note: Keep liquid use to a minimum on a mattress and avoid soaking it, since trapped moisture inside the padding can lead to mold or mildew.
Carpet
- Blot up any wet blood with a clean cloth, working from the outer edge of the stain inward.
- Mix cold water with a small amount of dish soap and apply it to the spot with a cloth, blotting rather than scrubbing.
- For a dried or set-in stain, apply an enzyme-based carpet cleaner and let it sit for the time listed on the label.
- Blot with a clean, cold, damp cloth to rinse, then let the carpet air dry fully.
Safety note: Stick to cold water throughout the process, since any warm or hot water can set the stain permanently in the carpet fibers.
