How to Clean a Bowl (if your wife rarely reads your blog)

I eat a bowl of Greek yogurt, peanut butter, and granola every morning-- and it's delicious-- but the down side is that it's very difficult to clean the bowl; even the dishwasher struggles to remove peanut butter and yogurt residue . . . so I've found the best, most environmentally copacetic way to remove this residue (without resorting to using a paper towel) is to let the dog lick the bowl clean . . . but my wife finds this gross-- luckily, she rarely reads this blog.
