Dampen the stain with warm water and apply baking soda to the area, enough to cover the stain about 1/4 inch (1/2 cm) thick. The baking soda will absorb the smell and also help lift the stain from the fibers. Pour lemon juice or vinegar over the stain. The baking soda will begin to fizz.Mar 10, 2017
Will puke smell go away?
Does vomit smell disappear? Yeah. Eventually. It dissipates over time, or if it's a spring day and you can open the windows to air out the room, you can remove vomit smell reasonably quickly.
How long does it take for the vomit smell to go away?
You can either open a bag of charcoal and leave it in, or you could simply put a few briquettes on a metal tray. Either way, your car will be rid of the nasty vomit smell in about 12 to 24 hours, depending how strong it is.
