How to Remove Blood from Carpet
This stain sets quickly. Start treatment as soon as possible for the best results. The longer you wait, the harder it becomes to remove completely.
Removal Method
Blot excess with a clean cloth. Apply COLD water only. Never use hot water on blood (heat sets protein stains permanently).
Mix 1 tbsp dish soap + 2 tbsp hydrogen peroxide (3%). Apply to the stain. Let sit 5 minutes.
Blot with cold water. Repeat until the stain lifts. For dried blood, apply hydrogen peroxide directly and let sit 10 minutes before blotting.
Meat tenderizer paste: mix unseasoned meat tenderizer with cold water into a paste. Apply to the stain for 30 minutes. The enzymes break down blood proteins.
- NEVER use hot water on blood stains (permanently sets the protein)
- Do not rub (spreads the stain and pushes it deeper)
