How to Remove Blood from Leather: Fresh vs Dried, Cold Water First

Blot the blood, then dab with a cloth barely dampened in cold water, and never wipe or use hot water. Extension guidance for fabrics says to treat blood with cold water because hot water can set the stain, and leather makers say to dab, not wipe, so the blood does not spread into the pores. Test everything on a hidden spot first, and stop as soon as the cloth picks up color.

This is one of the stains in our leather stain removal guide. For an unknown mark, use the general method in how to remove stains from leather.

Before you start: a hygiene note

Blood can carry infections. The US CDC says hepatitis B spreads mainly when an infected person's blood enters another person's body, and even very small amounts can be enough. A biohazard cleanup firm starts with disposable gloves and paper towel to blot up excess blood.

So wear gloves, bag the used towels, and wash your hands afterward. If the blood is not yours, or someone is injured, ask a health professional about any exposure. In workplaces, US rules require employers to decontaminate surfaces with an appropriate disinfectant after a blood spill. Disinfectants can harm leather, so see how to disinfect leather safely before you reach for one.

What you need

• Disposable gloves and paper towels
• Two or three white, lint-free cloths, so no dye transfers
• Cold water, ideally distilled, to avoid mineral marks
• A mild soap or a leather cleaner made for your type of leather
• Cotton swabs for small spots

How to remove fresh blood from leather

1. Blot at once. Dab with a clean cloth and do not wipe, because wiping pushes the blood into the pores. Press from the outer edge of the mark inward, using a clean part of the cloth each time.
2. Do the water test. Rub a drop of water on a hidden spot. If it darkens in, the leather is porous, such as aniline, and you should use the careful route in the finish table below.
3. Use cold water. Dampen a white cloth in cold water and wring it out so it is barely damp. Dab the stain, then blot with a dry cloth, and repeat until no more blood transfers. Extension guidance for fabrics describes this repeat-and-blot rhythm.
4. Try mild soap. If a mark stays, work up suds of mild soap in water on a cloth and dab. Check the cloth for dye as you go.
5. Wipe off the soap. Use a cloth dampened in plain water, then blot dry.
6. Dry slowly. Let the leather dry at room temperature, away from sun and heat.
7. Condition only if needed. Condition once it is fully dry and only if the area has dried out.

How to remove dried blood from leather

Dried blood is harder, and fresh is easier. We found no leather source with a tested method for old, dry blood. The closest guidance is repeated cold-water dabbing for fabrics, then a leather cleaner you have tested on a hidden spot.

1. Go slowly. Dab with a barely damp cloth in cold water, blot, and repeat. Do not scrub.
2. Move to mild soap suds only if cold water stalls.
3. After two or three careful rounds with no change, stop. A cleaning firm says leather polish can cover what remains as a last resort, and a professional can help if the stain stays.

Fresh vs dried blood at a glance

One forum post on saddles says slightly warm water softens blood better than cold. Extension guidance says cold first because hot water can set protein stains. We follow the cold-water advice, since it is the safer starting point and the forum post is one person's experience.

Blood on leather by finish

When to stop before hydrogen peroxide bleaches the dye

Peroxide shows up in many blood guides, so here is where the sources stand. One leather maker lists hydrogen peroxide for blood and red-dye stains. A cleaning firm quoted by that maker says to test first because it may bleach, and says drugstore strength bleaches least. A cleaning article says peroxide can fade dye, leave bleach-like spots and dry the leather.

If you try it, use a cotton swab on a hidden spot and stop at the first sign of lightening. Our full view is in can you use hydrogen peroxide on leather?. Do not use peroxide on suede, nubuck or anything you cannot test.

Blood on a leather jacket or couch

• Jackets. The same steps apply. A motorcycle clothing maker says its cleaning service may refuse items with blood or mud deep in the leather, which shows how hard set-in blood can be.
• Couches. Work in small sections and blot, and stop early if the leather is uncoated or the stain covers a large area. For serious stains, visit a professional leather cleaner.
