How to Get Vomit Smell Out of Mattress

Dealing with a vomit smell in your mattress can be both frustrating and unpleasant. Whether it’s because of a child’s upset stomach, a pet accident, or an adult’s illness, the lingering odor can disrupt your sleep and leave your bedroom feeling less than fresh. Many people feel overwhelmed when faced with this task, but with the right approach, you can fully restore your mattress to its original, odor-free state.

How to Get Vomit Smell Out of Mattress

This guide on how to get vomit smell out of mattress will walk you through simple yet effective solutions to eliminate vomit smells from your mattress completely. We’ll outline the tools and materials you’ll need, provide clear step-by-step instructions, and address common questions to ensure you’re confident throughout the cleaning process. By following these guidelines, you’ll be able to reclaim the comfort and hygiene of your sleeping environment in no time.

Tools and Materials You’ll Need

Before you begin, gather the following tools and materials to ensure the cleaning process is smooth and efficient:

  • Rubber gloves to protect your hands
  • Paper towels or absorbent cloths
  • A small bucket or a large bowl
  • Baking soda
  • White vinegar
  • A spray bottle
  • Mild dish soap
  • An enzymatic cleaner (optional but highly recommended)
  • Old toothbrush or soft brush
  • Vacuum cleaner with upholstery attachment
  • Clean water
  • Fan or hairdryer (for drying)
  • Airtight trash bag (for disposing of soiled materials)

Having these items on hand will make the cleanup easier, faster, and more effective in removing both the stain and the lingering odor. It’s important to act quickly, as prompt attention often prevents long-term damage and deep-set smells.

8 Simple Step-By-Step Guidelines on How to Get Vomit Smell Out of Mattress

Step 1: Remove Excess Vomit Immediately

The first step in addressing vomit on your mattress is to remove as much of the solid material as much as possible right away. Using paper towels or an absorbent cloth, carefully lift the solids off the surface. It’s crucial not to press or rub, as this can push the vomit deeper into the mattress fibers, making stains and odors harder to eliminate.

Mattress is to Remove as 
Much of the Solid Material

Once you have removed the majority of the debris, dispose of it in an airtight trash bag to prevent spreading the smell. This action also reduces the risk of the bacteria and odor becoming more ingrained in your mattress. Even if it feels inconvenient in the moment, quick action here will save you time and effort later on.

Step 2: Blot Up Moisture and Avoid Scrubbing

After clearing away the solids, the next important step is to absorb as much of the remaining liquid as possible. Take fresh paper towels or a dry absorbent cloth and gently blot the affected area. It is important to blot rather than scrub—excessive scrubbing will not only spread the mess but can force it deeper into the mattress.

Continue blotting until no more moisture can be absorbed. Don’t worry if the area is still slightly damp; the goal is to remove as much excess as possible. This sets the stage for the next round of deep cleaning and ensures that your later efforts will be more successful in neutralizing odors.

Step 3: Apply a Vinegar Solution for Deep Cleaning

Prepare a cleaning solution by mixing equal parts white vinegar and water in a spray bottle. White vinegar is excellent at neutralizing odors and breaking down organic matter. Lightly spray the affected area, avoiding oversaturation, which could lead to mold or mildew growth. Allow the vinegar solution to sit for 10–15 minutes so it can break down residual odors and germs.

After allowing it to soak, blot again with a clean, dry cloth to remove as much liquid as possible. You may repeat this process once or twice if the smell is particularly strong. The vinegar scent will fade away as it dries, taking much of the vomit odor with it and leaving your mattress much fresher.

Step 4: Use Baking Soda to Soak Up Odors

Generously sprinkle baking soda over the still-damp area of your mattress. Baking soda has natural deodorizing properties that help to draw out and neutralize stubborn smells. Gently pat the baking soda into the surface so that it can reach the source of the odor deep within the mattress fibers.

Gently Pat the Baking Soda 
Into the Surface So That

Allow the baking soda to sit for at least several hours—overnight, if possible—for maximum effectiveness. The longer it rests, the more odor it will absorb. During this time, the baking soda will not only help neutralize the smell, but it will also aid in drying out any remnants of moisture.

Step 5: Vacuum Thoroughly to Remove Residue

Once the baking soda has had sufficient time to work, use your vacuum cleaner’s upholstery attachment to thoroughly remove it from the mattress. Be sure to go over the area several times, as baking soda particles can sometimes settle deep into the fabric.

Vacuuming at this stage removes not just the baking soda but also any remaining dirt or debris loosened during the earlier steps. If you notice that some odor lingers, you can repeat the baking soda application for an added boost. A clean, vacuumed surface is essential for both comfort and odor removal.

Step 6: Treat With an Enzymatic Cleaner (If Needed)

If a stubborn smell persists after the previous steps, an enzymatic cleaner—especially one formulated for organic stains and odors—can be a game changer. Spray the cleaner directly onto the affected area, following the manufacturer’s instructions for application and dwell time.

Enzymatic cleaners work by breaking down the proteins and organic compounds found in bodily fluids like vomit, targeting the source of the smell rather than just masking it. Once the recommended time has elapsed, blot the area once again with a clean cloth to remove excess moisture. This extra step is particularly helpful if you notice recurring odors after initial cleaning.

Step 7: Allow the Mattress to Air Dry Completely

It’s imperative to allow the mattress to dry completely after cleaning to prevent the growth of mold or mildew. If the weather permits, open windows to increase airflow in the room. Alternatively, use a fan or hairdryer set on cool to expedite drying. Avoid making the bed or putting sheets back on until you are confident the mattress is fully dry.

Check the area a few hours after finishing the cleaning process. Mattresses can sometimes feel dry on the surface but remain damp inside. Ensuring complete dryness not only eliminates odor but also preserves the integrity and longevity of your mattress.

Step 8: Prevent Future Odors With Regular Maintenance

Once your mattress is clean and odor-free, establishing a routine can help ward off future problems. Consider using a waterproof mattress protector, which acts as a barrier against spills, stains, and accidents. Wash your bedding regularly and vacuum your mattress monthly to prevent dust and buildup.

Establishing a Routine Can Help 
Ward Off Future Problems

Taking preventative measures keeps your mattress fresh, healthy, and comfortable for years to come. This not only saves time and hassle but also contributes to a restful and pleasant sleeping environment for you and your family.

Following these steps on how to get vomit smell out of mattress and keeping it clean can help you maintain your mattress for a longer period of time. Remember, prevention is key when it comes to maintaining the cleanliness and longevity of your mattress.

Frequently Asked Questions

Q1: What If The Vomit Smell Doesn’t Go Away After Cleaning?

If the vomit smell lingers even after following the recommended cleaning steps, try repeating the vinegar solution and baking soda treatments. Sometimes, stubborn odors require multiple rounds. Using an enzymatic cleaner can also be very effective for persistent smells. Be patient and don’t hesitate to reapply as needed, as lingering scent molecules may take time to fully break down.

Q2: Is It Safe To Use Bleach On My Mattress?

Bleach is not recommended for cleaning mattresses, especially memory foam or fabric surfaces. It can damage mattress fibers and leave behind harsh chemical residues. Instead, use gentle yet effective alternatives like white vinegar, baking soda, and enzymatic cleaners. These options remove odors without risking harm to your mattress material or your health.
