What You Need to Remove Vomit Stains

Before you start, gather the right tools and cleaning agents to effectively break down the stain without damaging the fabric.

• Cold Water – Prevents the stain from setting and rinses out excess vomit.
• Baking Soda – Absorbs moisture and neutralizes acidic components.
• White Vinegar – Helps break down proteins and eliminate odors.
• Liquid Dish Soap – Lifts grease and proteins from the fabric.
• Hydrogen Peroxide (for Whites & Color-Safe Fabrics) – Works as a gentle bleaching agent for stubborn stains.
• Enzyme-Based Stain Remover (OxiClean, Zout, or Biokleen) – Breaks down protein stains more effectively than regular detergents.
• Lemon Juice (for Natural Stain Removal) – A mild bleaching agent for lighter fabrics.
• Laundry Detergent with Enzymes – Essential for breaking down organic matter.
• Soft-Bristle Brush or Toothbrush – Helps work the cleaning solution into the fabric.
• Absorbent Paper Towels or Clean Cloths – For blotting excess vomit before washing.
• Bucket or Large Bowl – For soaking heavily stained clothing before washing.

Having these items on hand makes it easier to act fast and prevent the stain from becoming permanent.

What to Do Immediately After Vomit Gets on Clothes

The faster you act, the better your chances of completely removing the stain.

Step 1: Remove Excess Vomit

• Use a paper towel, spoon, or dull knife to gently scrape off any solid material.
• Avoid rubbing, as this can push the stain deeper into the fibers.

Step 2: Rinse with Cold Water

• Hold the stained fabric under cold running water from the back of the stain.
• This helps flush out the particles instead of embedding them deeper.
• Do not use hot water yet, as heat can permanently set the stain.

Step 3: Pre-Treat the Stain

Before putting the garment in the washing machine, use one of the following methods to break down the stain.

Best Methods to Remove Vomit Stains from Clothes

Method 1: Baking Soda and Vinegar (For Fresh Stains)

Why it Works: Baking soda absorbs acid and moisture, while vinegar breaks down proteins and removes odors.

Steps:

1. Sprinkle a generous amount of baking soda onto the stain.
2. Let it sit for 10-15 minutes to absorb moisture and neutralize acid.
3. Pour white vinegar onto the baking soda. The fizzing reaction helps lift the stain.
4. Scrub gently with a soft-bristle brush or cloth.
5. Rinse with cold water, then wash as usual.

Method 2: Enzyme-Based Stain Remover (For Protein-Based Stains)

Why it Works: Vomit contains proteins, and enzyme cleaners are designed to break them down.

Steps:

1. Apply an enzyme-based stain remover (OxiClean, Zout, or Biokleen) directly onto the stain.
2. Let it sit for 15-30 minutes to break down the proteins.
3. Wash in cold water with a regular enzyme-based detergent.

Method 3: Dish Soap and Hydrogen Peroxide (For Stubborn Stains on White Clothes)

Why it Works: Dish soap lifts grease and proteins, while hydrogen peroxide is a mild bleaching agent.

Steps:

1. Mix one tablespoon of dish soap with one tablespoon of hydrogen peroxide and two cups of cold water.
2. Apply the mixture to the stain and let it sit for 10 minutes.
3. Blot with a clean cloth, then rinse with cold water.
4. Wash as usual in cold water.

Method 4: Lemon Juice and Salt (For Delicate Fabrics Like Wool and Silk)

Why it Works: Lemon juice acts as a natural bleach, and salt helps absorb moisture.

Steps:

1. Sprinkle salt over the stained area.
2. Squeeze fresh lemon juice onto the salt.
3. Let it sit in the sun for 15-20 minutes (only for light-colored fabrics).
4. Rinse with cold water and hand wash the garment.

Method 5: Ammonia Solution (For Heavy Vomit Stains on Durable Fabrics)

Why it Works: Ammonia breaks down protein-based stains effectively.

Steps:

1. Mix one tablespoon of ammonia with one cup of cold water.
2. Dab the stain with a cloth soaked in the solution.
3. Let it sit for 5 minutes, then rinse with cold water.
4. Wash as usual.

How to Remove Vomit Odor from Clothes

Even if the stain is gone, vomit odor can linger. Here’s how to fully eliminate the smell:

• Add Vinegar to the Wash Cycle – Pour one cup of white vinegar into the fabric softener compartment to neutralize odors.
• Use Baking Soda in the Wash – Add ½ cup of baking soda to your detergent for extra odor removal.
• Dry Clothing in Fresh Air – Sunlight helps disinfect fabrics and eliminate lingering smells naturally.

What to Do If the Vomit Stain Has Already Set

If the stain has been left untreated for several hours or days, follow these steps:

1. Soak the Clothing in Cold Water – Let it sit for 1-2 hours before applying stain removers.
2. Apply an OxiClean and Water Paste – Let it sit for 30 minutes, then rinse.
3. Wash with a Heavy-Duty Detergent – Use a detergent with enzymes for deep cleaning.
4. Repeat Treatment if Needed – Some older stains may require multiple treatments.

Mistakes to Avoid When Removing Vomit Stains

1. Using Hot Water Too Soon – Heat can permanently set the stain.
2. Scrubbing Too Hard – Can damage delicate fabrics and push the stain deeper.
3. Skipping the Pre-Treatment Step – Directly washing vomit-stained clothes can make removal harder.
4. Drying Clothes Before the Stain is Fully Removed – The heat from the dryer will set any remaining stain permanently.

Final Thoughts

Vomit stains don’t have to ruin your clothes if you act fast and use the right methods. By using the right pre-treatment, washing techniques, and odor-removal steps, you can restore your clothing to a stain-free, fresh-smelling condition.

The key is immediate action, cold water rinsing, and enzyme-based stain removers. If a stain has already set, multiple treatments and oxygen-based cleaners can still help restore the fabric.
