Cleaning dried grease stains is hard but not impossible, and you can again make the cloth clean. Take the cloth, and add a pinch of baking soda over the stain. Next, squeeze a lemon over it, and rub it gently.  The granules of baking soda break down the stain and help remove it, while the lemon juice helps protect the fabric. Once done, toss the cloth in the washing machine, and it’s done.
