If you strip it with regular bleach, which will clean the dingy, you have to put a new linoleum finnish back on it or else it will be dull and dirty looking again right away. When you use bleach, it strips all of the finish off of the floor. JUst make sure you replace it with a sponge mop after the bleaching and you will be fine. You can buy it at Home Depot or most stores, easy to find.
