Good Morning B., you might try spraying the area with white vinegar and water, let it dry and then sprinkle a little bit of baking soda on it. kind of dust it in to the material. Unfortunately I use this to get the pp smells ( from puppy) out of my carpet. My doggie is 1 now and I am still finding puddles once in a while.. grrrrrrrrrrrrrr
God Bless hope something helps, I remember busting a gallon of Milk on my floorboard when I was like 17. We went to the dairy twice a week. When that car got hot, the smell was sicking...
Have a blessed day
