This week, DDB/S.F. debuts what is arguably the second best campaign we've ever seen for a bathroom tile cleaner. (The best, of course, was the Gold Lion-winning "Prison Visitor" spot for Vim from directing team the Perlorian Brothers and Toronto agency Zig. Tough category suddenly.) In a series of 15-second spots for Tilex -- directed by Villains' Douglas Avery -- we see quick cuts of people who just can't handle the fact that "all homes have mold." Like it or not, these people need some Tilex, which positions itself here as "The Mold Killer."
