Take appropriate precautions to prevent the spread of disease when handling blood or blood products.
Most fresh blood stains can be removed with cold water.
For fresh blood, pat the stain with a cloth dabbed in cold water and then blot the stain with a clean dry cloth. Repeat the process until no more blood transfers to the cloth.
Dried blood may be more difficult to soften and remove.
Before washing, gently scrape the dried blood with a fingernail file or similar object.
Avoid bruising the suede. Use a soft toothbrush to break up the blood, then use the cold water and cloth method discussed above.
If water alone does not work, try a dilute solution of a mild soap such as Woolite, Joy, Dove, or Ivory in cold water.
Do not use warm or hot water as it may set the blood into the suede.
