The successful removing of blood from a carpet depends very much on the used methods and cleaning products. It is not recommended using solutions that are warm or hot when removing blood, as the protein in the blood causes these stains to adhere firmly to the fibers when exposed to heat, making it near impossible to remove the stain. The best way to deal with blood stains is to treat them with cleaning solutions that are cold. Cold liquids break down the bonds of the blood with the carpet fibers so they can be successfully removed.
