Is it better to blot or rub a blood stain?

You should always blot, never rub, a fresh blood stain, as rubbing pushes the blood deeper into the fabric and can damage fibers, while blotting lifts the blood out; use a clean, cold, damp cloth and dab the stain, working from the edges inward, then rinse with cold water and repeat until gone, using stain removers on stubborn spots before washing in cold water.

Use 30°C for darks, delicates, and lightly soiled items to save energy and prevent fading; use 40°C for most everyday cottons and mixed fabrics that need a more thorough clean.
