Evan's had been stinky for a while but I couldn't figure out why.
I lysoled it, frebreezed it, and bleached it to no avail.
So I got it ready to run it through the washer, pulling out miscellaneous wrappers and crumbs when I noticed a strangely colored spot on what I thought was the fabric of one pockets.
Not so much.
That solved that mystery.
