Getting rid of vomit smell from sofa cushions

[spydie]

Poor DD has been quite unwell and vomited over both our sofas the covers are removable and have gone through the wash. However the seat cushions stink! They are foam and I've used the stain remover on them that usually sorts odours (cat vomit...) but they still stink.

Any ideas? Other than 2 new sofas!?

Diluted zoflora.

Used for dog sick, it works.

Second bicarb.

Soap powder in warm water.

Another vote for bicarbonate of soda. Used it in the car for vomit smell after lots of cleaning products failed, and it worked a treat.

I used an animal odour spray in the end as we had some stashed away, the kind with enzymes that neutralizes urine smells, since it had mostly dried already. Worked a treat!!
