After the vinegar has had its moment, blot up the excess liquid with a dry towel. Then, sprinkle a thick layer of baking soda over the entire area. We’re talking a heavy coating, like you’re dusting a giant donut. Baking soda is the sponge of the gods. It absorbs moisture, smell, and your lingering shame.
Now, walk away. Seriously. Leave it for at least 6-8 hours. Go binge a show. Take a nap on the couch. The baking soda is working the night shift. When you come back, vacuum it up. The smell should be gone, and the stain should be a faint shadow of its former self.
If the stain is still there, repeat the cold water and vinegar step. Persistence is the only thing that beats biology. You are stronger than stomach acid.
The Secret Weapon: Enzyme Cleaner (If You’re Serious)
If the vomit is old or you’re dealing with a stubborn yellow halo, go to a pet store and buy an enzyme cleaner. Yes, the kind for dog pee. Enzimatic cleaners literally eat the organic matter. Spray it on, let it dry, and watch the stain disappear like your hopes of a clean sleeping surface ever again.
