Several television stations broadcasted a television commercial for a product named "Kober Zertifikat Plus", a washable paint.
The commercial began with displaying a test room and a voice claiming that "a simple test shows how the product is able to eliminate 99,99% of the existing housing bacteria during the first 24 hours after it is applied".
The advertisement ended with a text alleging that the antibacterial effect was tested in German and Japanese labs.
However, it was established that the antibacterial effect was tested only on 2 specific types of bacteria.
