Let’s be frank. Airbnb guests are downright awful dishwashers. How do we know this? Because of the sheer number of sticky (or grimey or smelly or stained) dishes we’ve encountered during our travels. At this point, when we pick up a glass in an Airbnb, we instinctively raise it to our nose for a quick sniff and glance inside before getting a drink of water.

And while we’d like to think that we personally do a decent job leaving Airbnb dishes a little better than we found them, most guests aren’t thinking much about future guests as they wash the dishes. Usually they’re keeping an eye on the clock. It’s likely the morning of checkout, maybe an hour left in their stay, and they’re doing a slapdash job cleaning out the sink before heading out the door.
