If you allow blood spots to set and dry into fabric, they become notoriously hard to remove. Rinse the spot on clothing as quickly as possible in cool water while gently chafing the fabric between your fingers. If this can’t be done right away, blot the spot with a cloth or paper towel moistened with cool water. If you act quickly enough, any remaining shadow or ring likely will disappear once the garment is washed.
For set-in blood stains, soak colorfast fabrics in an enzyme cleaner such as Biz or Shout!, and then rinse with water. Use mild laundry detergent on non-colorfast garments.
Strategies for cleaning stains on carpeting or upholstery are complicated by the stain-fighting chemicals frequently applied to these materials. Blot carpets with paper towels dampened with water and a tiny amount of dishwashing liquid; blot dry once the spot is gone.
Depending on the application process used, spot cleaning upholstery with water or solvents may — or may not — be recommended. To protect any warranty that may be in force, check for a care label underneath the furniture or read any printed instructions that came with the piece. If neither is possible, consult with the retailer who sold the furniture, or check the manufacturer’s website for a section such as “care and maintenance,” which may include helpful tips.
