If you don't believe it, I have my pile rotting foam and rusted IC's
in the closet. I'll post a photo when (and if) I recover from my
latest culinary disaster.

Here's an example. My guess is about 15 years in the back of the
closet. I'll confess to having a roof leak about 10 years ago, which
may have aggravated the problem:

I don't have a sample of the foam that crumbled. Just visualize the
black foam turning to anything between dust and crumbs when moved.
