Dirt speaks

Clean Plus provides a sign that it's cleaning time.

This really cool execution for Clean Plus by McCann Worldgroup in Thailand, promoting its cleaning services, lets the dirt in its clients’ offices, service apartments and factories do the talking. As time passes, dust adheres to the poster’s surface, eventually revealing office appliances, furniture or factory icons depending on the location it’s posted, with the tagline ‘It’s cleaning time. Call us.’
