To remove olive oil stains from cotton, start by dabbing the stain with a paper towel to absorb as much of the oil as possible. Next, apply baking soda to draw out the oil, and massage with dish soap and hot water to remove the remaining oil. This process requires paper towels, baking soda, liquid dish soap and hot water.
- Dab the stain with a paper towel
Use a dry paper towel to dab the stain. Change to a new paper towel as needed to avoid transferring oil back to the material. Press firmly on the stain several times to remove as much oil as possible.
- Apply baking soda to the stain
Press baking soda onto the olive oil stain, and gently rub the baking soda into the stain. Let it sit for at least 15 minutes. Dust the baking soda off the material, and check the stain. If the stain is still noticeable, apply more baking soda, and let it sit for another 15 minutes.
- Massage with liquid dish soap
Remove the baking soda, and apply liquid dish soap to the remaining stain. Thoroughly massage the dish soap into the stain for a few minutes, then rinse with hot water. Repeat this process as needed until the stain is gone.
