How to remove dry cat vomit stains

Because the acid in cat vomit can stain quickly, it's best to clean vomit stains as soon as possible. But sometimes you can be surprised to find dry cat vomit on your carpet or furniture. You must remove not only all of the dried-on vomit but also its odour so you don't have a smelly surface even after the vomit stain is gone.

Using your vacuum attachments, remove as much dry vomit from the surface of your carpet or furniture as possible.

Pour club soda on the stain. Starting at the outer edges of the stain and working toward the middle, blot the stain with a clean white cloth.

Rinse your cloth frequently with plain water, and apply more club soda to the stain, if needed. Continue to blot until no more stain transfers to your cloth.

Press a clean, dry cloth onto the surface to wick out moisture from the club soda. Keep moving to a dry part of the cloth until no moisture remains.

Cover the stain with baking soda. Let the baking soda remain in place overnight to remove odour and to dry out the surface.

Vacuum up the baking soda, and sprinkle a liberal amount of pet odour neutraliser onto the spot. Leave the neutraliser on the spot for several hours so the enzymes can break down and absorb any remaining odour or bacteria.

Using your hose attachments, vacuum the pet odour neutraliser from your carpet or furniture.


Cat vomit that's yellow means it has bile in it and should be sprayed with a disinfectant spray as well as club soda.
