Step-by-Step Removal Method

  1. Scrape off any excess grease. Use a dull knife or spoon to gently lift off any hardened grease. Be careful not to spread it.
  2. Apply dish soap directly to the stain. Squirt a small amount of liquid dish soap onto the grease spot. Gently rub it in with your fingers or a soft brush. Dish soap is designed to cut through grease.
  3. Sprinkle baking soda over the soap. Cover the area with a generous layer of baking soda. The baking soda will help absorb the oil and lift it from the fibers.
  4. Let it sit for 15-30 minutes. This gives the dish soap and baking soda time to work on the grease. For very set-in stains, you can leave it for up to an hour.
  5. Gently scrub the stain. Use a soft-bristled brush or an old toothbrush to work the mixture into the fabric in a circular motion. Avoid scrubbing too hard, as it can damage the cotton fibers.
  6. Rinse with warm water. Hold the apron under warm running water to rinse out the soap and baking soda. Check if the stain is gone.
  7. If the stain remains, repeat the process. Sometimes set-in grease needs a second treatment. You can also try a pre-treatment stain remover before washing.
  8. Wash the apron as usual. After the stain is gone, wash the apron in the washing machine with your regular detergent, following the care label instructions. Use the warmest water setting that is safe for the fabric.

What Not to Do

  • Do not use hot water on the stain before treatment. Heat can set the grease further into the fibers.
  • Avoid rubbing the stain with a cloth. Rubbing can push the grease deeper. Always blot or gently scrub.
  • Do not dry the apron until the stain is completely removed. The heat of the dryer will set the stain permanently.

Fresh vs. Set-In Stains

If the grease is fresh, you can often remove it by blotting with a paper towel to absorb excess oil, then applying dish soap and washing. For set-in stains, the baking soda method is more effective because it gives the degreaser time to break down the oil. The steps above are tailored for set-in stains, but you can adapt them for fresh ones by skipping the soaking time.
