How to Remove Grease Stains from a Cotton T-Shirt

A single drop of oil or butter can leave a dark mark that’s hard to ignore. But don’t worry — removing grease from a cotton t shirt is easier than you think. With a few simple steps, you can restore your shirt’s clean look without damaging the fabric.

 

These methods work for all types of cotton, including premium Supima cotton t shirts, known for their softness and durability.

Why Grease Stains Stick to Cotton

Cotton’s absorbent fibers trap oil quickly. When that oil dries, it leaves behind translucent patches that regular washing won’t remove. To fix this, you’ll need to lift and dissolve the grease before laundering.

Method 1: Dish Soap (Best for Fresh Stains)

Dish soap cuts through grease effectively — just like it does on cookware.

Steps:

  1. Place the shirt flat and put a paper towel under the stain.
  2. Apply a few drops of dish soap (clear and mild).
  3. Gently rub with your fingers or a soft brush.
  4. Let it sit for 10–15 minutes.
  5. Rinse with warm water, then wash as usual.

This method is safe for Supima cotton t shirts, which are delicate yet resilient.

Method 2: Baking Soda (For Set-In Grease)

If the stain has dried or survived a previous wash, use baking soda.

Steps:

  1. Sprinkle baking soda generously over the stained area.
  2. Let it sit for 30–60 minutes to absorb the grease.
  3. Brush off the powder gently.
  4. Add a drop of dish soap, scrub lightly, and rinse.
  5. Wash on a warm cycle.

Baking soda naturally breaks down oil and neutralizes odor without harming fine cotton.

Method 3: Vinegar and Warm Water Solution

For stubborn or large stains, vinegar is a great natural degreaser.

Steps:

  1. Mix 1 part white vinegar with 2 parts warm water.
  2. Soak the stained area for 10–15 minutes.
  3. Add a few drops of dish soap and rub gently.
  4. Rinse and wash as usual.

This combo removes deep grease while keeping Supima cotton soft and smooth.

Method 4: Cornstarch or Baby Powder (Gentle Option)

Perfect for lightweight or white shirts.

Steps:

  1. Cover the stain completely with cornstarch or baby powder.
  2. Let it sit for several hours (or overnight).
  3. Brush it off carefully, then wash as usual.

This method gently draws oil out of cotton fibers without any scrubbing — ideal for delicate Supima cotton t shirts.

Important: Avoid Heat Before the Stain Is Gone

Never use a dryer or iron on a stained shirt. Heat will “bake in” the grease, making it permanent. Always air dry after treatment and check under bright light before using heat again.

How to Keep Cotton Stain-Free

  • Wash cotton tees regularly in warm (not hot) water.
  • Treat stains immediately before washing.
  • Avoid fabric softeners — they can trap oil residue.
  • Store shirts folded and away from kitchen splashes or lotions.

FAQs About Grease Stains on Cotton

Can I use hot water to remove grease?
Warm water is best — hot water can set the stain before it’s lifted.

 

Does baking soda really work on old grease?
Yes — it absorbs oil that’s already embedded in the fabric.

 

Will vinegar discolor cotton?
No, white vinegar is safe for all cotton types, including Supima.

 

Can I dry the shirt in sunlight?
Yes, after the stain is gone. Sunlight naturally deodorizes cotton.

Removing grease from a cotton t shirt doesn’t require special chemicals — just simple household ingredients like dish soap, baking soda, and vinegar.
