Whether you nick yourself while shaving or receive an unexpected scratch, it’s important to treat blood stains on your clothing as soon as possible; blood stains are relatively easy to remove before they set but can be nearly impossible to wash out after 24 hours. If you can get to the stain before it sets, remove blood stains by pouring full-strength white vinegar on the spot. Let it soak in for five to ten minutes, then blot well with a cloth or towel. Repeat if necessary, then wash immediately.
