Removing set-in grease stains (grease stains that have already dried or been through the dryer) takes more effort than treating fresh stains, but many can still be removed with the right method.

Why grease stains are difficult

Grease and oil are hydrophobic, meaning they repel water. During washing and especially drying, heat can cause the oil to bond more firmly to the fabric fibres, making the stain harder to remove.

Common grease stains include:

• Cooking oil
• Butter and margarine
• Salad dressing
• Bacon grease
• Motor oil
• Lotion and body oils
• Makeup and sunscreen

Method 1: Dishwashing Liquid (Most Effective)

Dishwashing liquid is designed to break down grease and is often the best first treatment.

What you’ll need

• Liquid dish soap (preferably one formulated for grease)
• Soft toothbrush or small brush
• Warm water
• Laundry detergent

Steps

1. Lay the garment flat.
2. Place a towel underneath the stained area.
3. Apply enough dish soap to completely cover the stain.
4. Gently rub it into the fabric with your fingers or a soft toothbrush.
5. Let it sit for 15–30 minutes.
6. Rinse thoroughly with warm water.
7. Wash according to the care label using the warmest water safe for the fabric.
8. Air-dry the garment.
9. Check whether the stain is gone before using a dryer.

Repeat if necessary.

Method 2: Baking Soda + Dish Soap

This works well for older or heavy grease stains.

You’ll need

• Baking soda
• Dish soap
• Toothbrush

Instructions

1. Sprinkle baking soda generously over the stain.
2. Leave it for 30–60 minutes so it can absorb oil.
3. Brush off the powder.
4. Add a few drops of dish soap.
5. Scrub gently.
6. Let sit for another 15 minutes.
7. Wash normally.
8. Air-dry and inspect.

Method 3: Enzyme Laundry Detergent

Many modern laundry detergents contain enzymes that help remove food and grease stains.

Instructions

1. Apply liquid detergent directly to the stain.
2. Rub gently.
3. Leave for 20–30 minutes.
4. Wash using the warmest temperature allowed on the garment’s care label.
5. Check before drying.

Method 4: White Vinegar (For Residual Marks)

White vinegar won’t dissolve grease by itself, but it can help remove detergent residue and lingering marks.

1. Mix equal parts white vinegar and warm water.
2. Soak the stained area for 20 minutes.
3. Wash with detergent.
4. Air-dry.

Method 5: Rubbing Alcohol (For Tough Grease)

Suitable for some sturdy fabrics.

Steps

1. Test on a hidden area first.
2. Dab rubbing alcohol onto the stain.
3. Leave for 10–15 minutes.
4. Blot with a clean cloth.
5. Wash immediately.

Do not use on delicate fabrics without checking the care instructions.

Method 6: Heavy-Duty Laundry Stain Remover

Commercial stain removers formulated for grease can be very effective.

Instructions

1. Spray or apply the stain remover directly.
2. Wait the recommended time on the label (often 5–15 minutes).
3. Wash as directed.
4. Repeat if needed.

If the Garment Has Already Been Through the Dryer

Heat can set grease stains, but they may still come out.

1. Apply dish soap.
2. Let it sit for 30–60 minutes.
3. Scrub gently.
4. Wash.
5. Air-dry.

Older stains often require multiple treatments.

Things to Avoid

• Don’t put the garment in the dryer until the stain is gone. Heat can make the stain much harder to remove.
• Don’t use bleach unless it is appropriate for the fabric and colour.
• Don’t iron over a grease stain.
• Avoid using very hot water on delicate fabrics.

---

Prevention Tips

• Treat grease stains as soon as possible.
• Blot excess grease with a paper towel instead of rubbing it deeper into the fabric.
• Keep a small stain-removal product available in your kitchen or laundry room.
• Inspect clothes after washing and before drying to make sure stains are gone.

Quick Reference

With patience and repeated treatment, even many set-in grease stains can be removed or significantly faded. The key is to avoid additional heat until you’re sure the stain has disappeared.
