This is the bin where we store all the dog food, and the day before it was time to refill it we were going to dump out the hand full that was left and wash it out. But the dogs were going nuts because we were NEAR THE FOOD BIN, TOUCHING THE FOOD BIN, LOOKING AT THE FOOD BIN, so I took pity, saved some water and let them have a go. And afterward that bin was cleaner than the day we'd bought it.
