To remove fresh blood stains, simply rinse with cold water and wash the fabric like usual. For older stains, it is best to use a Stain Remover
. If you do not have a stain remover at home, soak the stained fabric in 1 tablespoon salt and 1 dl water for a couple of hours. Avoid using warm water, as it can make the stain permanent. If the stain remains, mix two parts baking soda with one part water, let it soak for half an hour, then brush off the excess and dab with a damp cloth before washing.
