How to remove vomit stains from clothing
Scrape any solids off the garment.
As with any stain, the faster you move to treat the stain, the more success you will have removing it. This may be particularly difficult with vomit, since handling clothing covered with vomit is not very appealing, but it's in your best interest to work quickly.
Rinse the stain with warm water. If treated immediately, a strong blast of water may be enough to get the vomit out of your clothes.
