If you're sure it's an oil stain, pour a very little bit of Dawn dish soap onto a clean, damp cloth. Rub in gently until the stain is gone. With another clean damp cloth, wipe over the stain until the Dawn has been removed. With a paper towel, blot the area well, then let it air dry. I have a Micro Plush couch also %26amp; most stains will come off with cold water. If it's oil, you need a degreaser, which is why I suggest Dawn dish soap.
