iabu as I'm posting for traffic.
On way back from holiday recently a whole pint of (full fat if it makes a difference) milk managed to get spilled onto DS pram. I only noticed the next day but have stripped it as far as I can, washed the detachable bits, wiped down and scrubbed the non detachable bits with soapy water twice and left in garden. Still smells 
It seems to be emanating from the crease of the seat so in my desperation I've just febreezed for fabric like a maniac and put it back outside. If this doesn't work what can I do?!
Obviously its nice weather and ds is nearly getting too big for it and I want to sell it soon so we want to be out for walks, preferably without smelling like sour milk!
