How to Remove Set-In Grease from a Cotton T-Shirt

1. Blot the stain: Place a clean cloth under the stain and blot the area with a paper towel to absorb any excess grease. Don't rub, as this can push the grease deeper into the fibers.
2. Apply dish soap: Squirt a small amount of dish soap directly onto the stain. Gently work it in with your fingers or a soft brush. Dish soap is designed to break down grease.
3. Let it sit: Allow the dish soap to sit on the stain for 10-15 minutes. This gives it time to penetrate the grease.
4. Add baking soda: Sprinkle a generous layer of baking soda over the dish soap. Baking soda is a mild abrasive and helps absorb grease. Let it sit for another 10-15 minutes.
5. Gently scrub: Using a soft-bristled brush or old toothbrush, gently scrub the stain in a circular motion. Be careful not to be too aggressive, as this can damage the cotton fibers.
6. Rinse with warm water: Rinse the area with warm water to remove the dish soap and baking soda. Check if the stain is gone. If it's still visible, repeat steps 2-5.
7. Wash as usual: Once the stain is gone, wash the t-shirt in the washing machine using the hottest water safe for the fabric, according to the care label. Use your regular laundry detergent.
8. Air dry: After washing, air dry the shirt. Do not put it in the dryer until you're sure the stain is completely gone. Heat can set the stain permanently.

What Not to Do

• Don't use hot water on fresh grease: Hot water can cook the grease into the fabric. Use warm or cool water for the initial treatment.
• Don't rub the stain: Rubbing can spread the grease and push it deeper into the fibers. Always blot or dab.
• Don't use bleach on cotton: Bleach can weaken cotton fibers and cause yellowing. Stick to gentle methods.
• Don't dry the shirt until the stain is gone: Heat from the dryer can set the stain permanently, making it nearly impossible to remove.

Fresh vs. Set-In Stains

Fresh grease stains are easier to treat because the oil hasn't had time to bond with the fibers. For fresh stains, blot immediately and apply dish soap right away. You can often skip the baking soda step for fresh stains.

Set-in stains, like the one this guide focuses on, require more patience. The baking soda and dish soap combination is effective, but you may need to repeat the process a few times. If the stain is very old, you might also try a pre-treatment stain remover, but test it on a hidden area first.

Alternative Methods

If dish soap and baking soda don't work, you can try white vinegar. Mix one part white vinegar with two parts water and apply it to the stain. Let it sit for 10 minutes, then blot and wash. Vinegar helps break down grease and neutralize odors.
