Clearing vomit from any surfaces is probably one of the most unpleasant jobs of being a parent. Just follow these steps to clear the vomit stains from any surface.
Do not use hot water. It will hold the protein stench to the fabric.
Remove vomit stains. Start by scraping as much excess vomit as possible from the carpet or clothing by using a plastic scraper and blotting with paper towels. Run cold water through the stain to force the stain out through the fabric.
Treat and scrub. Sprinkle a pinch of baking soda on half a lemon and scrub it on the stain. Apply Surf Excel liquid detergent on it and soak in cold water. You can also use 1 tablespoon of ammonia and ½ a tablespoon of Surf Excel liquid detergent for carpets and other surfaces.
Use a toothbrush. Scrub away the stains with a brush. Use a sponge for carpets or sofas to absorb the stain.
Let it sit. Set it aside for 3 to 5 minutes. Wash in warm water, using a liquid laundry detergent.
