Fearless cleaners

I always wondered how skyscrapers and generally tall buildings remain clean from the outside. It seems that the traditional way is the one used in order to clean them. However a few are fearless enough to do this job, since they have to hang and clean at the same time, whilst being hundreds of metres above the ground.
