At this point, do not dry in the dryer. An enzyme presoak works well on protein stains like blood, body fluids and grass. WASH garments using small loads and a full water level. Do not overload washer. Use the hottest water safe for fabrics being washed.
Some detergents have color-safe bleach or bleach alternative built into the product.
However, remember that these products do not disinfect. Other products sanitize and control odors. Follow label directions for proper use in the laundry. IF there are rust or rust-colored stains on fabrics, use a commercially prepared rust remover to help remove them. Look for these products in the laundry or fabric dye section of the supermarket.
