Of course clean the carpeting with Windex or similar cleaner (non soap) that will remove dirt and greases. You hand press the carpet one direction forcing the nap to lay down. Mark the location for your decal with timing marks as getting them straight is pretty deceiving. Remove the backing and apply the logo with reasonable force, pressing it thoroughly once you locate it. Take a terry cloth towel and an iron, use a medium to medium high setting as the polypropylene carpet strands cant handle high heat. Slowly press the logo down with the iron on the terry cloth towel. You should be good to go then! BCB
