She was sick few days ago in her cot, it went through the protection sheet thingy, I tried sponging it off but still smelled. Turned the matress over and she had diarrhoea all over it last night (she has a some sort of stomach bug at the mo).
Short of buying a new matress, is there anything I can do to get rid of the smell?
I think it went into the sponge bit iyswim
