Blood stains are easier to manage when you treat them before heat and drying enter the process. For washable clothing, the safest starting point is usually simple: cold water, an appropriate laundry pretreatment, and a check of the care label before washing.
This guide is intended mainly for everyday washable clothing. Dry-clean-only garments, silk, wool, and other delicate fabrics may need different care.
Rinse a fresh blood stain with cold running water. Pretreat any remaining mark with liquid laundry detergent or a stain remover suitable for the fabric, then wash according to the care label. Check the stained area before using the dryer. If the mark is still visible, treat it again first.
Blood is a protein-based stain. Heat can make a blood stain more difficult to remove, so cold water is the better starting point for rinsing and initial treatment.
Check the Garment Before You Treat the Stain
Blood
Cold water
Washable clothing
Drying too soon
Read the garment care label before applying a stain remover, bleach, or other laundry treatment. A method that is acceptable for a washable cotton T-shirt may not be suitable for silk, wool, a dry-clean-only garment, or a fabric with unstable dye.
What You Need
- Cold running water
- A clean white cloth or paper towel
- Liquid laundry detergent or a fabric-safe stain remover
- An enzyme-based laundry pretreatment if appropriate for the garment
You do not need to start with several household remedies at once. A simple laundry treatment is easier to control and makes it easier to follow the directions for both the garment and the product.
How to Remove a Fresh Blood Stain
Rinse With Cold Water
Hold the stained area under cold running water. When practical, rinse from the back of the stain so the water carries residue away from the fabric rather than farther through it.
Blot Instead of Scrubbing
If excess moisture or blood remains on the surface, press it gently with a clean white cloth. Avoid aggressive scrubbing, especially on knits, delicate surfaces, or fabrics that can pill.
Pretreat the Remaining Stain
Apply a liquid laundry detergent or stain remover that is suitable for the fabric. Enzyme-containing laundry products can be useful for protein-based stains, but use the amount and treatment time specified on the product label.
Wash According to the Care Label
Once the stain has been pretreated, wash the garment using a cycle and water temperature permitted by its care label. Do not increase the temperature simply because the stain is difficult.
Check Before Using the Dryer
Inspect the stained area while the garment is still wet. If you can still see a brown, red, or shadow-like mark, pretreat and wash it again before machine drying.
What If the Blood Stain Has Already Dried?
A dried stain usually needs more time than a fresh one, but the process does not need to become complicated.
Start by rinsing or soaking the washable garment in cool water. Then pretreat the remaining stain with a laundry product designed for stain removal. An enzyme-based pretreatment may be useful when it is compatible with the fabric.
After treatment, wash the garment according to the care label and check the stain before drying. More than one treatment may be needed for an older stain.
Should You Use Hydrogen Peroxide?
Hydrogen peroxide is sometimes used on persistent blood stains, but it should not be the automatic first step for every garment. It may affect the color or finish of some fabrics.
If you consider using hydrogen peroxide or a bleaching product, first confirm that the garment and product instructions allow it and test the product on an inconspicuous area. A standard laundry pretreatment is a better first choice for many everyday garments.
Common Mistakes That Make Blood Stains Harder to Handle
- Starting the first rinse with hot water
- Scrubbing delicate fabric aggressively
- Using several cleaning products together
- Ignoring the garment care label
- Putting the garment in the dryer while the stain is still visible
When to Stop Treating It at Home
Stop repeated home treatment if the fabric begins to lose color, the surface changes, or the care label does not allow the method you are using.
Dry-clean-only clothing, silk, wool, valuable garments, and items with special finishes are better handled according to their care instructions or by a professional cleaner.
