To get motor oil out of clothes, first use the lifting motion to blot the oil from the fabric and sprinkle the stain with cornstarch or baby powder. Let it sit with the powder for five to ten minutes and remove the powder with a nail brush or paper. Next, put one or two drops of dishwashing liquid on the stain with a little water and rub using your thumb. Take a brush and try rubbing the soap into the fabric in circular motions. Finally, wash the fabric as usual and hang it on a hanging line or place it flat on the ground.
