Just 1 question will decide who enters The Human Carwash and who enters The Gunge Tank. The person in the carwash is guaranteed to get very messy, however at the end of the ride, 2 ropes await the mucky losing contestant. One of the ropes is connected to the grand finale of the carwash, the other is attached to the gunge tank release above the winning opponent. Both contestants are unaware as to which is connected to which.
