I only rarely drink milk, but this morning I bought a plastic bottle (one pint) and drank part of it on the way to work. After I’d been at work for a while, I realized that I’d left the milk in the car, so I went out to fetch it. I opened the car door, reached in, and grabbed the bottle. Unfortunately the cap wasn’t screwed on tightly, and I wound up with milk all over myself, the driver’s seat, and other parts of the car.
I ran in for some paper towels to wipe it up, but some of it must have soaked into the leather seat and the carpet. I’m afraid that it’s going to smell terrible later today. Google turned up this article on how to deal with it.
