Cleaning up vomit, blood, or other fluids in a car can be an unpleasant but necessary task. Whether caused by motion sickness, an accident, or unexpected spills, these messes not only create discomfort but can also lead to stains, odors, and potential health risks if you don’t address them properly. A quick cleanup is essential for maintaining your vehicle’s hygiene and comfort.
This guide provides a straightforward approach to tackling these tough messes. Following the right procedures and using the correct supplies can effectively restore your car’s interior. We will walk through the necessary steps to clean, disinfect, and deodorize your vehicle, ensuring it is safe and pleasant for you and your passengers.
First Cleaning Steps to Take
Your first priority after an incident is to act quickly. The longer fluids sit, the deeper they seep into upholstery and carpeting, making them much harder to remove. Prompt action minimizes staining and helps control odors before they become overwhelming.
Begin by safely pulling over if you are driving. Open the car doors and windows to ventilate the area, which helps disperse strong smells and aids in the drying process.
Essential Supplies
Gathering the right cleaning supplies is crucial for effectively handling bodily fluids. You will need personal protective equipment, such as disposable gloves and a face mask, to protect yourself from exposure to germs and biohazards.
Assemble paper towels or old rags for blotting, a plastic scraper for solid waste, and a bucket of cold water. An enzymatic cleaner is essential, as it contains enzymes that break down the proteins in organic matter like vomit and blood. You will also need a quality disinfectant to kill any remaining bacteria and viruses.

Step-by-Step Cleaning for Vomit
Start the cleaning process by removing any solid material. Use a plastic scraper or a similar tool to lift the waste from the surface without rubbing it deeper into the fabric. Dispose of the waste in a sealed disposable bag.
Next, blot the affected area with paper towels or a clean cloth to absorb as much liquid as possible. Avoid scrubbing, as this can spread the stain. Continue blotting with fresh towels until you can’t pick up any more moisture.
Apply an enzymatic cleaner generously to the entire soiled area. These cleaners are specifically designed to break down the organic compounds that cause stains and odors. Allow the cleaner to sit for the time recommended on the product label, typically between 10 and 15 minutes.
After the enzymatic cleaner has had time to work, gently blot the area again with a clean, damp cloth. Use cold water to rinse the cloth frequently. Repeat this process until all traces of the cleaner and the stain are gone.
Finally, dry the area thoroughly. You can use a fan, a hairdryer on a cool setting, or simply leave the car doors open in a well-ventilated space. Ensure the upholstery is completely dry to prevent the growth of mold and mildew.
Step-by-Step Cleaning for Blood
Cleaning blood stains also requires a specific approach. Always use cold water, as hot water can cause the proteins in blood to set, making the stain permanent. Begin by blotting the fresh stain with a cloth dampened with cold water.
For dried blood stains, you may need a slightly different technique. Create a paste of cold water and salt or baking soda. Apply the paste to the stain and let it sit for about 30 minutes before scrubbing it gently with a soft brush.
After pre-treating the stain, apply an enzymatic cleaner. Follow the same procedure as you would for vomit, allowing the cleaner to penetrate the stain before blotting it away with a damp cloth.
Scrub the area thoroughly with cold water, making sure to remove all cleaning residues. Dry the fabric completely to avoid any musty smells or mold growth. Proper drying is just as important as the cleaning itself.
Odor Elimination
Even after a thorough cleaning, lingering odors can remain. Leave the car windows open for as long as possible to allow fresh air to circulate and carry away unpleasant smells.
Baking soda is an excellent natural deodorizer. Sprinkle a generous layer over the cleaned and dried area, and let it sit for several hours or even overnight. The baking soda will absorb any remaining odors from the fabric.
After letting it sit, vacuum the baking soda thoroughly. For persistent odors, you can also place a bowl of white vinegar or a container of activated charcoal in the car overnight. These substances are highly effective at absorbing and neutralizing strong smells.
If these methods are not enough, a professional-grade odor eliminator or an ozone treatment might be necessary. These options are more potent and can often remove even the most stubborn odors from your vehicle’s interior.

Prevention Tips
Preventing future incidents is always better than cleaning up after them. If you or your passengers are prone to car sickness, there are several remedies you can try. Over-the-counter medications, ginger candies, or acupressure wristbands can help alleviate nausea during travel.
For pets, ensure they are securely contained in a carrier or with a pet seatbelt. Avoid feeding them a large meal before a car trip. Having spill-proof containers for drinks and snacks can also prevent messes before they happen.
When to Seek Professional Help
While many situations can be managed with DIY cleaning methods, some are best left to professionals. If the bodily fluid has soaked deep into the car’s seats or carpets, a professional detailer has the equipment to perform a deep extraction cleaning.
For significant contamination involving large amounts of blood or other biohazards, it is safest to contact a specialized bio-remediation service. These professionals are trained to handle hazardous materials safely and effectively. For incidents such as these, call Affinity Bio Solutions for biohazard car detailing and professional assistance.
