Olive oil can clean and condition your leather surfaces, but if you apply too much olive oil you may end up with a stubborn stain. The leather soaks up the oil and cleaning solutions cannot budge it. Although it may seem like an effective method to clean up the oil, applying solvents to the leather does not remove the olive oil. Sometimes these solvents can even cause the oil to spread, making a larger stain. Absorbent materials such as cornstarch actually draw the oil from the leather, leaving no residue behind.
Sprinkle a light layer of cornstarch directly onto the olive oil stain.
Rub the cornstarch lightly into the leather until you feel the leather becoming warmer under your fingers. Be careful not to scratch the leather or rub too hard. As the leather warms, the pores open and the cornstarch can absorb the olive oil.
Wipe away the cornstarch with a dry, soft cloth and check to see if the olive oil stain is still present.
Repeat the cornstarch until the olive oil is completely removed. Depending on the size of the olive oil stain, you may need to repeat this process several times. With patience, you can remove even large stains.
