Part 2: Step-by-step method

For fresh stains, you can often treat them with dish soap and warm water. Dish soap is designed to cut through grease.

  1. Apply dish soap: Squirt a small amount of liquid dish soap directly onto the stain.
  2. Gently rub: Use your fingers or a soft-bristled brush to work the soap into the fabric. Rub in a circular motion for about a minute.
  3. Let it sit: Allow the soap to sit on the stain for 5 to 10 minutes.
  4. Rinse with warm water: Rinse the area thoroughly with warm water to remove the soap and oil.
  5. Launder as usual: Wash the shirt in the washing machine using the hottest water safe for the fabric (check the care label). Use your regular laundry detergent.
  6. Check before drying: After washing, check the stain. If it's still visible, repeat the treatment or try the baking soda method below. Do not put the shirt in the dryer until the stain is gone, as heat can set the stain permanently.

How to Remove Set-In Olive Oil Stains

If the stain has dried or been through the dryer, you'll need a stronger approach. Baking soda is a gentle abrasive that can help lift the oil.

  1. Make a paste: Mix baking soda with a little water to form a thick paste.
  2. Apply the paste: Spread the paste over the stain, covering it completely.
  3. Let it sit: Leave the paste on the stain for at least 30 minutes. For stubborn stains, you can leave it for up to an hour.
  4. Scrub gently: Use a soft-bristled brush or an old toothbrush to gently scrub the paste into the stain.
  5. Rinse and wash: Rinse the area with warm water, then launder as usual.
  6. Repeat if needed: If the stain remains, repeat the process or try the dish soap method again.

What Not to Do

  • Do not use hot water on fresh stains: Hot water can set the oil stain into the fabric. Use warm or cold water for initial treatment.
  • Do not rub the stain: Rubbing can spread the oil and push it deeper into the fibers.
  • Do not dry the shirt until the stain is gone: Heat from the dryer can make the stain permanent.
  • Avoid harsh chemicals: Bleach or strong solvents can damage cotton fibers or discolor the fabric.
