How To Clean Vomit From Car Exterior


Ever had a vomiting accident in your car? People often vomit out the window instead of inside the car. That’s not a good idea though, vomit can damage the paint job. If somehow vomit got on the exterior of your car, you may be wondering: How to clean vomit from the car exterior?

  1. Spray vomit stain with WD-40
  2. Let the goo loosen up
  3. Wash off the vomit
  4. Wash your car
  5. Re-polish & Wax

The cleaning process depends on how big and dry the vomit is. A step-by-step guide follows.

Can Human Vomit Damage Car Paint

Everyone has been in a situation where some of the car passengers had to puke. Whether it’s from being drunk or it’s just a bad road, it’s an unpleasant situation.

The best thing to do in these situations is to stop the car and let the person puke outside. You can’t always do that. For instance, if you stop on a highway you may cause a crash.

The intuitive thing that people do is puke out the window. That way, there will be no stain on the seats. More so, you don’t have to deal with the vomit smell.

However, that may not be a great idea. The vomit will stick to the side of your car. It contains stomach acid. And we all know that any type of acid is bad for the paint.

If you are wondering whether stomach acid is strong enough to damage car paint, yes it is. For the first few minutes, your car may be safe. But if it dries and becomes solid matter, there will be a stain on the exterior.

Now, how quickly you get rid of the vomit is really important. Dried vomit leaves a stain and it’s much harder to get rid of. Vomit is best cleaned when it’s fresh.

How To Clean Fresh Vomit

If you are lucky enough to be able to quickly clean the vomit, you don’t have to worry about anything. Stomach acid is strong enough to damage the paint job but not that fast.

Fresh vomit on a car is cleaned just by rinsing with a water hose. All you have to do is hose down the stain. Make sure you are pushing it down, and not contaminating the rest of the car.

Remember, this only works if the incident happened in your yard for instance. So, you are able to quickly hose the vomit. You can’t do this while you are driving.

Let’s say that you were able to get to a car wash or to your house in a few minutes. You should still rinse with a garden hose. There are high chances that you will have a stain though.

So, you still may have to get rid of some dried vomit and treat the stain with something. We will talk about that soon.

How To Clean Dry Vomit

The worst scenario is vomiting outside the car’s window on a long trip. The truth is, you won’t be able to stop and clean the stain. Nor you will be able to find a car wash, especially if you are on the highway.

By the time you are able to clean the car, there will be a lot of dry pieces of solid matter. The liquid will turn into a stain. Your car’s paint will stain like it started to fade.

I agree, this is not ideal. Don’t worry though, there is a solution. Your car won’t look like that always. There are three ways to approach this.

Cleaning Method 1

Cleaning Method 1

The best way to clean a vomit stain is to go to a car wash and pay for the right cleaning services. Take your car to a professional cleaner service. These places offer the usual car wash but will treat vomit stains specifically for an additional charge.

The thing is, you can’t be sure if your car will need re-polishing and other treatment. Also, the cleaning solution you will be using matters too. These places have cleaning solutions specifically for vomit stains.

Cleaning Method 2


If you feel like you can clean the stain on your own, by all means, do it. You will also have to re-polish and wax the exterior.

  1. Soak up any liquid left with paper towels.
    I don’t think there will be any liquid left but just to be sure, check if there’s any left.
  2. Apply a bug & tar remover or WD-40.
    You need to use something that will dissolve the goo and acid. There are plenty of cleaning products you can choose from. I recommend a bug & tar remover or WD-40.
  3. Let the stuck vomit dissolve.
  4. Wash off the vomit.
    Just a quick rinse with a water hose will do.
  5. Wash the entire car.
  6. Repolish your car.
  7. Add a coat of wax.

If you do this right, and the stain is not that bad, you may have gotten rid of the stain. If the stain persists, go to a professional.

Method 3

I know that some of you don’t want to choose something as strong as WD-40. So, there’s something you can use as a mild solution.

  1. Mix Dawn Dish Soap With Water. 
    In a bucket of water, add Dawn Dish Soap. It’s the strongest dish soap but still mild enough for your car.
  2. Soak a microfiber towel in the bucket.
    Don’t let it be soaking wet. Just absorb the soapy water. Make sure you are using a damp cloth on the car.
  3. Place the damp cloth over the stain.
    Try to stick it to the stain.
  4. Hold the cloth over the stain.
    This should dissolve vomit. But it a good period of time. The soap is not that strong, so it takes time for the vomit to dissolve.
  5. Wipe away the dissolved matter.
  6. Rinse with hose.
  7. Wash the car with shampoo.
  8. Re-polish & wax.
