Office, Service Apartment, Factory

Dust accumulates but it can’t be seen, so clients don’t use a cleaning service as often as they should. To let them know it’s time for cleaning, we let the dirt speak. We created posters covered with clear glue, placing them in the offices, service apartments and factories of our clients. As time passed, the sticky parts of the posters would capture dirt and form shapes of office appliances, furniture or factory icons. The dirt would also stick to a headline that said: ‘It’s cleaning time. Call us.’ This reminded our clients that it was time to be cleaned again.
