Removing Grease Stains from Cotton: A Step-by-Step Guide

Grease stains can be a nightmare — especially on your favorite cotton T-shirt or cotton-blend pants. Whether it’s cooking oil, motor grease, or a rogue French fry slip-up, these stains don’t go away with a basic wash.

At The CoBuilders, we don’t just clean spaces — we help our clients and contractors stay sharp with real-world cleaning know-how. In this guide, we’re breaking down exactly how to remove grease stains from cotton so you can save your wardrobe (and your sanity).

Why Grease Stains Stick to Cotton

Cotton is absorbent and breathable, which makes it great for clothing and linens — but it also means that oil-based stains can soak deep into the fibers. If not treated correctly (and quickly), the grease can bond with the cotton, making it harder to lift over time.

Step-by-Step: Removing Grease Stains from Cotton

Step 1: Act Fast

The sooner you treat the stain, the better. Blot the area with a dry cloth or paper towel — don’t rub, or you risk pushing the grease deeper into the fabric.

Step 2: Apply a Dry Absorbent (Optional)

If you're not near water, sprinkle baking soda, cornstarch, or baby powder directly on the stain. Let it sit for 5–10 minutes to absorb as much grease as possible. Then gently brush it off.

Step 3: Use Dish Soap

Dish soap is designed to cut through grease — and it's safe on most cotton fabrics. Apply a few drops directly onto the stain. Gently rub it in with your fingers or a soft-bristled toothbrush.

Let it sit for 5–15 minutes before rinsing with warm water.

Step 4: Rinse and Launder

Rinse the treated area with warm water, then wash the cotton garment on the hottest setting that’s safe for the fabric (check the care label!).

Add a little oxygen-based bleach (like OxiClean) for extra stain-fighting power, especially for white or light-colored fabrics.

Step 5: Air Dry First

Avoid tossing the item in the dryer until you’re sure the stain is gone. Heat can permanently set the grease. Instead, let the garment air dry and inspect it — if the stain is still there, repeat the steps before drying again.

Bonus Tip: What Not to Do

• Don’t use bar soap — it can set oil stains, not remove them.
• Don’t rub aggressively — this can damage cotton fibers or spread the stain.
• Don’t skip checking the care label — some cotton blends may require cooler water or delicate cycles.

Grease Stain FAQs

Q: Can you remove an old grease stain from cotton?

Yes — but it may take more than one round of treatment. Use a mix of dish soap and baking soda, and let it sit longer before washing.

Q: Is vinegar good for grease stains?

White vinegar helps remove odors and some food stains, but it’s not the most effective on grease. Stick with dish soap for oil-based messes.
