I accidentally spilled milk in my trunk. Probably about a cup's worth. What an awful, awful messs. I did my best to soak it up, but it's July, and about 3 days later the cabin and trunk smelled so bad you can barely stand to be in the car. I tried Resolve carpet cleaner and Turtle's Wax Oxy interior cleaner. I also sprayed it with Oxy Clean. It's helped, but it still stinks. Any suggestions?
This happened to a friend of mine a while back
Only way to get rid of it completely was to remove the trunk carpet and liner, clean then both outside of the vehicle and let them air dry
While they are out you will want to clean the trunk floor metal as well
