Removing Rotten Juice Smell in Car?

I recently bought a box of "juices" (a juice ice block you have to freeze). I forgot to take the ice blocks inside and came back to them in my car a few days later exploded. They left my car smelling like rotten juice. The juice exploded onto my back seats and has sunk into them. I've tried cleaning my seats with a rag of cold water and also have tried air fresheners and nothing is working. If anyone is able to help that would be great!
