There are a few things you can do to clean vomit out of a car.

  1. Pour a pot of boiling water onto the vomit and let it sit for a few minutes. This will remove most of the vomit and make the car smell better.
  2. Use a plunger to push the vomit out of the way and pour cold water over it to cool it down. This will help to clean the car and remove any residue from the vomiting.
