Blood stains are protein-based, making them particularly stubborn. When you notice a blood stain, never use warm or hot water – this will cause the stain to set permanently by cooking the proteins into the fabric. Whether dealing with period blood or accident-related stains, cold water is your best friend when you need to get blood out of clothes. Denim and other sturdy fabrics can handle aggressive treatment, but delicate materials require gentler approaches.
Fresh Blood Stain Removal
Step 1: Immediate Cold Water Treatment
When you notice a blood stain, act immediately:
- Remove the garment and rinse the stained area with cold water as soon as possible
- Use a clean cloth soaked in cold water to blot the stain
- Continue rinsing until water runs clear
- Never put the garment in the dryer until the stain is completely gone
Step 2: Hand Soap Method
If cold water alone doesn’t help get blood out:
- Apply liquid laundry detergent directly to the damp stained area
- Work gently with fingertips using circular motions to treat the stain
- Let sit for 10 minutes, then rinse with cold water
- Wash your jeans in a cold wash cycle
Step 3: Enzymatic Treatment
For stubborn fresh stains:
- Apply enzymatic detergent or stain remover to target stains
- Soak the stain for at least 30 minutes for enzymes to break down the protein
- Rinse thoroughly before washing
- This method is easier to get results with than harsh chemicals
Remove Dried Blood Stains
Dried blood requires different approaches since proteins have bonded with fabric fibers. These stubborn stains need patience and specific steps to remove effectively.
Hydrogen Peroxide Method
Using hydrogen peroxide works well for white jeans and light fabrics:
- Test on hidden area first (avoid using on rayon or acrylic)
- Apply 3% hydrogen peroxide directly using cotton ball
- Watch for foaming action – this means it’s working to break down the protein
- Let sit 5-10 minutes, then rinse with cold water
- Be careful with dark denim as hydrogen peroxide can cause bleaching
Meat Tenderizer Method
- Mix powdered meat tenderizer and water to make a paste
- Apply paste to stain and let sit 30 minutes
- The enzymes in tenderizer help break down protein bonds
- Rinse thoroughly with cold water
Oxygen Bleach Treatment
For tough dried stains on denim:
- Mix oxygen bleach powder with cold water according to package directions
- Soak the stain for 30 minutes to 2 hours
- This gentler alternative to chlorine bleach won’t damage colors
- Rinse thoroughly and wash garment normally
Baking Soda Treatment
- Make a paste with baking soda and cold water
- Apply to stained area and gently work into fabric
- Let sit for 30 minutes before rinsing
- This method is gentle on all fabric types including delicate denim
Step-by-Step Guide for Treating a Blood Stain
For Fresh Stains:
Following these steps will help get blood stains out effectively:
- Rinse with cold water as soon as you notice the stain
- Apply small amount of detergent directly to the stained area
- Blot with clean cloth soaked in cold water
- If stain persists, apply enzymatic cleaner to treat the stain
- Wait 15-30 minutes for treatment to work
- Rinse thoroughly with cold water
- Check if stain is still visible before washing
- Wash in washing machine on cold setting
- Air dry – never put in dryer until stain is gone
For Dried Stains:
Use these steps to remove stubborn stains:
- Scrape off any dried blood flakes
- Choose appropriate method (hydrogen peroxide for white jeans, enzymatic for dark denim)
- Apply treatment and let work for recommended time to treat blood stains effectively
- You may need to repeat steps 2-3 multiple times for stubborn stains
- Once stain is gone, wash the garment normally
- Air dry to ensure complete removal
Important Tips for All Blood Stains
Always remember:
- Cold water as soon as possible prevents stain setting
- Much blood requires multiple treatments – don’t give up

- Never use warm water on blood stains whether fresh or dried
- If stain has set, it may need several treatment cycles
- Follow the step-by-step guide exactly for best results
Common mistakes when trying to remove blood stains:
- Using hot water (causes proteins to cook into fabric)
- Putting garment in dryer before stain is completely gone
- Giving up after first attempt
- Mixing cleaning products without testing
When Blood Stains Like These Need Professional Help
Seek professional help when:
- Multiple home treatments have failed
- Jeans are expensive, vintage, or sentimental

Remember to always air dry after treatment and never rush the process by using heat.
FAQ: Common Questions About Blood Stain Removal from Denim
For dried blood stains, I recommend starting with an enzymatic cleaner specifically designed for protein stains. Apply the cleaner directly to the stain, let it work for 15–30 minutes, then rinse with cold water. For stubborn stains, try the hydrogen peroxide method or a paste made from meat tenderizer and cold water. Multiple treatments may be necessary for complete removal.
Yes, blood can be successfully removed from denim jeans in most cases. Fresh blood stains have a 95% success rate when treated promptly with cold water and proper techniques. Even dried blood stains can be removed with the right approach, though they may require multiple treatment cycles and specialized products.
Cold water is essential because blood is a protein-based stain, and heat causes proteins to coagulate and bond more tightly with fabric fibers. Hot water essentially “cooks” the blood into the fabric, making removal much more difficult or impossible. Always use cold water (60°F or below) for blood stain treatment.
For quick removal of fresh blood stains, immediately rinse the stain with cold water from the back of the fabric. If cold water alone doesn’t work, apply liquid hand soap directly to the stain, work it in gently, and rinse. For faster results on stubborn stains, use an enzymatic cleaner designed for protein stains.
Dried blood stains are not permanent in most cases, though they are more challenging to remove than fresh stains. With proper treatment using enzymatic cleaners, hydrogen peroxide, or other specialized methods, most dried blood stains can be successfully removed. The key is persistence and using the right technique for your specific situation.
Create a paste using baking soda and cold water, apply it to the stain, and let it sit for 30 minutes before rinsing. While baking soda can help with some blood stains, it’s not as effective as enzymatic cleaners or hydrogen peroxide. For best results, use baking soda as a preliminary treatment before trying more effective methods.
The most effective products are enzymatic cleaners like Carbona Stain Devils #4 or OxiClean MaxForce. For household alternatives, hydrogen peroxide (3% solution) is highly effective, especially on fresh stains. Always test any product on an inconspicuous area first to ensure it won’t damage or discolor your jeans.
