Natural sugar can do more than make your coffee sweet. For grass-stained clothes, try making a sugar paste to lift the stains out of the fabric. Simply make a thick paste with white sugar and warm water. Apply the mixture to the stain, rub it in gently and let the paste sit for at least an hour. The sticky mixture will absorb the grass stain naturally, and since there are no fats or lipids in sugar, it will easily wash out in a normal wash cycle.
