2026.02.04

車内に嘔吐物があるのは最悪の混乱の一つです. それ自体が心地よい光景ではありません, そして、物理的な証拠が取り除かれても、その臭いは忘れがたいものになるかもしれません. 乗り物酔いや、病気の乗客、ペットの胃の不調などが原因かもしれません, でもどちらにせよ, proper cleaning and elimination of smell is what will be needed to clean up your car interior to its fresh and sanitary state. This step process guide encompasses easy, hassle free approaches that can be adopted by any car owner in approaching this challenge.

How to Clean Up Vomit in Your Car

Why It’s Important to Act Quickly

Vomit does not merely spot, and when touching non-fabric surfaces like seats of cars, carpets, or other upholstered surfaces, the organic content of vomit can soak to the core of the fibres resulting in difficult to remove stains and odors. The more it is left the more the odour attaches itself to the fibres and padding making it more difficult to take off in the future. To maximize on the process, the cleaning should commence as soon as you realize the mess as opposed to postponing.

What You’ll Need

Before starting, gather these common cleaning tools and supplies:

Absorbent cloths or paper towels
Kitchen towels or microfiber towels
Baking soda (natural odour absorber)
Vacuum cleaner (ideally wet/dry)
Warm water
Gentle cleaning solution (dish soap or mild cleaner)
オプション: enzyme cleaner, steam cleaner

Being prepared helps you clean more efficiently and prevents the mess from spreading further into the car surfaces.

方式 1 — Remove, Vacuum and Neutralize Odour

This technique focuses on quick absorption, stain removal, and odour neutralization — all using basic tools.

歩 1: Remove the Fresh Vomit

Begin by removing as much of the fresh vomit as possible. Use cloths, paper towels, or disposable materials to lift the solids and excess liquid off the seat, carpet, or floor. Avoid rubbing — その代わりに dab gently so you don’t push the mess deeper into the material.

歩 2: Absorb Excess Moisture

次に, use absorbent towels or microfiber cloths to soak up leftover liquid. The priority is to get rid of moisture that could seep further into fibres. Press the towel lightly — don’t exert too much pressure, as that can spread the residue and expand the area you need to clean.

If you have a wet vacuum, now is a great time to use it. A wet/dry vacuum can extract liquid and solids more effectively compared to cloths alone.

歩 3: Apply Baking Soda for Odour Removal

After removing the bulk of the mess, sprinkle a generous layer of baking soda over the affected area. Baking soda is an excellent natural odour absorber — it helps draw smells out of the fabric. Let it sit for about 30 分, then vacuum it up thoroughly.

If odour persists, consider steam cleaning with extraction or enzyme cleaners next.

方式 2 — Freshen the Interior & Eliminate Lingering Smell

Cleaning the stain is only part of the job — bad odours can persist even after the surface looks clean. Here’s what to do next:

1. Ventilate Your Car

Open all doors and windows and let fresh air circulate through the interior for at least 30 分. Good airflow accelerates drying and helps dissipate lingering smells. Leave the car in a shaded, open space if possible.

2. Use Odour-Neutralizing Sprays

After thorough drying, you can gently mist an antibacterial fabric freshener over the treated area. This can further reduce smells and make the interior feel refreshed. Focus on spots where residue might still be present, such as seat edges and carpet seams.

3. Sunlight Helps

暖かい, shaded sunlight can help break down odour molecules. Parking the car under daylight with open doors gives fresh air and sun heat time to lift deeper smells out of fabrics.

Advanced Tips for Tough Cases

Here are additional techniques if the basic methods don’t fully remove the smell:

Use a Steam Cleaner

A steam cleaner with extraction can work extremely well on stubborn vomit stains and odours. The heat helps sanitise and lift residues that cloths can’t reach. Professional detailing tools often use steam for deep cleaning upholstery.

Enzyme Cleaners

If conventional cleaners aren’t fully effective, consider enzyme-based cleaners. These products break down organic material at a molecular level, which can be especially helpful for deep odour removal.

Avoiding Compressed Ozone

Some DIY guides mention ozone generators as a way to eliminate odours. While ozone can neutralize smell, it must be used with caution and typically only outside or by trained professionals due to potential health risks.

Focus on Hidden Spots

When cleaning vomit, don’t forget to check areas beyond the immediate stain:

Seat edges and seams: These often trap fluids.
Floor mats: Remove and clean separately if possible.
Under carpets: Liquid may have seeped underneath.
Seat belts and buckles: Wipe with a damp cloth and cleaner.

Trapped moisture or residue in these hidden spots can cause lingering odour even after surface cleaning.

When to Seek Professional Help

There are occasions when a DIY cleaning is not sufficient - particularly when vomit has saturated padding or seats or backed carpeting. Professional car detailing services would be useful in those instances with tools and products that would be used in removing stains and odours intensely.

塗装保護フィルム (PPF) or interior protection products or other tinting/protective coatings can be used to minimize future damages to your car and make it easier to clean up the next time or something to think upon when your car is clean again.
