Microfiber is a type of synthetic fabric made primarily of polyester. This durable material holds up well to constant use and does not fade or deteriorate over time. This makes it a popular choice for a variety of items including clothing, furniture and cleaning supplies. Nevertheless, even something as resilient as microfiber can be damaged by stains, especially blood. No matter what type of material it lands on, blood has proteins that, once dry, can be almost impossible to remove. With patience and perseverance, however, dried blood can be safely cleaned, restoring the appearance of microfiber fabrics.
Remove as much dried blood as possible before starting the stain removal process. Scrape any visible deposits with a butter knife or putty knife, slowly moving the edge of the knife against the grain of the fabric. Run the vacuum over the area to remove any loose, dried solids.
Reconstitute the remaining blood with a generous application of 3 percent hydrogen peroxide. Perform a spot test before attempting to treat a larger area. Dip the end of a cotton swab into the peroxide and rub it gently on an inside seam. Wait for the peroxide to dry, then visually inspect the fabric. If no color change has occurred, apply the peroxide to the stain, pouring a small amount directly onto the discolored portion of the fabric. As the solution begins to foam, blot it up with paper towels. Be careful not to rub, as this may cause the stain to spread.
Treat any remaining discolorations with meat tenderizer. Pour 1 tbsp. of meat tenderizer into a small bowl. Add enough water to make a thick paste. Spread the paste over the blood stain and scrub it into the fabric with an old toothbrush. Work from the outside edges toward the center, using small circular motions.
Leave the paste on the stain until it is completely dry. This will give the enzymes in the meat tenderizer time to break down the proteins in the blood. Remove the dry paste with a vacuum and rub the treated area with a baby wipe to remove any remaining residue. If the stain persists, repeat the entire procedure.
