## Recipe to Remove Set-In Grease Stains (Recipe in First Comment)

**Ingredients:**

* 1 tablespoon dishwashing liquid (preferably a grease-fighting brand like Dawn)
* 1 tablespoon baking soda
* 1 tablespoon white vinegar
* 1 teaspoon hydrogen peroxide (optional, for white or colorfast fabrics)
* Warm water

**Instructions:**

1. **Make a paste:** In a small bowl, mix dishwashing liquid, baking soda, and hydrogen peroxide (if using) to create a thick paste.
2. **Apply to stain:** Lay your stained garment flat and gently rub the paste into the grease stain using a soft toothbrush or cloth. Make sure to cover the entire stain thoroughly.
3. **Let it sit:** Allow the paste to sit on the stain for 30 minutes to an hour. Baking soda absorbs grease, while the dish soap breaks it down. Hydrogen peroxide helps lighten stubborn stains on whites.
4. **Rinse:** Rinse the treated area under warm water, rubbing gently to remove the paste.
5. **Vinegar soak:** Soak the stained area in a mixture of one part white vinegar to two parts warm water for 15-20 minutes to break down residual grease and neutralize odors.
6. **Launder as usual:** Wash the garment in the warmest water safe for the fabric, using your regular detergent.
7. **Air dry:** Do **not** put the garment in the dryer until you confirm the stain is completely gone; heat can set the grease permanently.

## Why Are Grease Stains So Tough?

Grease and oil stains are tricky because they are **hydrophobic**, meaning they repel water. This water resistance prevents normal washing from removing the oil molecules trapped in fabric fibers.

When grease sets in, it penetrates deeply into the fibers, bonding with the fabric through physical and sometimes chemical means. Heat (from washing or drying) can further bake the oil into the material, making the stain more resistant to removal.

Understanding this helps us realize why water alone is insufficient and why targeted agents like dish soap (which breaks down oil), baking soda (which absorbs it), and vinegar (which can neutralize residues) are essential.

## The Science Behind Each Ingredient in the Recipe

* **Dishwashing liquid:** Designed to cut through tough kitchen grease, it contains surfactants that surround and break down oil molecules, making them easier to wash away.
* **Baking soda:** A mild abrasive and absorbent, it lifts grease from fibers and deodorizes the fabric.
* **Hydrogen peroxide:** Acts as a mild bleaching agent, particularly useful for whitening stained fabrics. Avoid using on colored fabrics unless tested first.
* **White vinegar:** Breaks down residue, neutralizes odors, and softens fabric after treatment.

## Step-by-Step Techniques for Removing Set-In Grease Stains

### Step 1: Identify the Fabric Type

Before applying any treatment, check the care label. Natural fibers like cotton and linen generally tolerate stronger treatments than delicate fibers like silk or wool. For delicate fabrics, reduce treatment time or consider professional cleaning.

### Step 2: Pre-Treat the Stain

Use the recipe paste as described above. If the stain is fresh, gently blot with paper towels to absorb excess grease before applying the paste.

### Step 3: Gentle Scrubbing

Use a soft toothbrush or cloth to rub the paste into the stain with circular motions. Avoid aggressive scrubbing that could damage fabric.

### Step 4: Waiting Period

Allowing the paste to sit gives the ingredients time to penetrate and lift the stain. For particularly stubborn stains, you may leave the paste on for longer, up to 2 hours.

### Step 5: Rinsing and Soaking

After rinsing, soak the garment in vinegar solution to help loosen any remaining grease and restore fabric softness.

### Step 6: Washing and Drying

Wash in the warmest water safe for your fabric with a good-quality detergent. Always air dry after washing; heat from dryers can set any remaining grease stain permanently.
