Rope climbing training is essential
You will learn how to tie different kinds of knots, find out how to anchor the rope, and get to know all the tools involved. Those who haven’t been through training are not allowed to hang down the side of a building. Sometimes you need to combine two ropes when you’re cleaning your way down a skyscraper, which is why knowing how to tie a knot properly is essential. A rope-access certificate is even required at some companies.

Not every building has bolt anchors on the rooftop
Especially newly-built buildings. So you need to use weight stacks to anchor the rope by setting them up against anything upright; for example, a water tank or a wall. After that you need to lead the rope against the anchored object and find something to tie a knot on, such as a sturdy fence, then use the rope to lead you down the building.
The worst-case scenario must be considered every time you perform the job
Accidents can happen if you fail to check all the safety measures and the conditions of your tools. You need to check these things very carefully before every job: the ropes, safety harnesses, carabiners and climbing pulleys. These are basically the same tools used by mountain climbers. If one of these is not in perfect condition, it needs to be replaced immediately. You should always work as a team so there’s always someone helping you. And make sure you keep your body close to the building at all times.
Windows of brand-new buildings are usually the most difficult to clean
Because of construction materials left on the surface such as defects and wall paint. Another hard task is wiping off stains from old buildings’ windows. You need to use different kinds of cleaning agents suitable for each requirement.
