Crime scene cleaner Heiko Schotte cleans at record speed. If he completes his cleaning job by half past three, he might still make it in time for the Mud Olympics.

In this new episode of "A Licence to Clean" we find out what the Mud Olympics are, whether Schotty will arrive on time after all, and how many currants you need for a cake.
