Looks like a leaky roof, doesn’t it? It isn’t. It’s Dr Pepper. Nathan put one in the freezer, left it too long, and then opened it immediately when he pulled it out.
To his credit, he cleaned it up very well—and it really was everywhere. Agitated Dr Pepper don’t play.
I’ll hit this with some diluted bleach in a spray bottle a few times over the course of the next couple of weeks and see what happens.
