10 questions stand in the way of our contestant staying clean, we even give them two possible answers, but is it answer A or answer B? They have a 50 / 50 chance of picking the right one to avoid the gunge.

Joe wears the full Chelsea kit with socks and enters the tank. Each time he gets a question wrong, a mixture of red and black gunge is poured over him. At the end of the game he wipes the gunge off the kit and then steps out of the tank.
