Cream Rinse Off

How to diminish the foul smelt fuzz fabric under the carpet of my car?
I have accidentally spilled a carton of full cream milk over my car two days back. I tried washing it off with shower foams, rinsed in hot water and air-dried but it doesn’t seem to work. I was hesitant to use any detergent that may damage my fuzz fabric. The smell is profusely strong. Please advised. Thank you to all in advance.
Seriously now, take the car to a detailer and let them get the milk and smell out. It will require removing the carpet and padding to get it all out, then reinstalling the pad and carpet. It will look like new and smell even better. Worth it, and you will not break a sweat or a nail.
