History of Window Cleaning

Are you wondering about the backstory of window cleaning? We have five interesting historical facts regarding window cleaning.

  1. Construction boom: Thanks to the construction boom in 1860, the demand for window cleaners began. With more buildings and, therefore, more glass, more window cleaners were required.
  2. Then came the squeegee: The best way to clean windows is with a squeegee. The original squeegee, which originated in the early 1900s, was big and heavy.
    In fact, a fisherman’s tool used to scrape the fish residue off boat decks was used as inspiration. In 1936, the modern-day squeegee, which we know and recognize today, hit the market.
  3. Windex hits the market: Windex, one of the most popular window cleaning products, appeared in 1936. During the Great Depression, Philip Drackett invented the famous glass cleaner.
  4. The Victorian way: Before the invention of the squeegee and Windex, Victorian servants or housewives would clean their windows with hot water, a bucket, and cleaning cloths. If necessary, they would add vinegar to shine the windows up and tackle grease. They even used newspapers to give it a final polish. What’s really cool is that we still use this technique today!
  5. The 1990s changed everything: The squeegee held its ground for many decades, but the water-fed pole system changed how professionals clean windows. This makes it much easier and quicker for window cleaners to get the job done without the need for ladders or cherry pickers.

Window Cleaning Safety

Window cleaning isn’t one of the safest jobs in the world. There come many risks with window cleaning. Here are some key facts.

  1. Before scaffolds: Thankfully, we now have scaffolding, which makes this job safer. But before scaffolding and secure platforms, window cleaners used window ledges to lean on taller buildings. In fact, one man from the 1900s would suspend a wooden chair using rope and hook a cotton belt around his waist to scale a building. Deaths were not uncommon back then.
  2. Weather makes for danger: A window cleaner must always check the weather before starting their working day (1). They shouldn’t work in extreme heat or expose themselves to too much sun. Windy days aren’t safe either. Some companies prohibit workers from cleaning in winds higher than 25 miles per hour. And to top it off, they shouldn’t work in the extreme cold either. There are a lot of factors that can make this job more dangerous.
  3. Falling hazard: The main risk for window cleaners is falling. To prevent this, window cleaners must work on surfaces with edge protection, such as a structural parapet or a guardrail at least 42 inches tall. They should also use a full body harness, rope grab, a lanyard, and an anchor point as fall protection. Cleaners must never walk on overhead glass in a skylight or atrium, making these windows more challenging to clean.
  4. Ladders are dangerous: While you might think hanging from a rope to clean windows is more dangerous, that’s not true these days. The fall protection in place is very effective. In the US, there has been only one high-rise death per year for the last four years. In fact, most falls from a window cleaner occur using portable ladders.
  5. Long pole systems are preferred: If a window cleaner can keep both feet on the ground and use a long-pole system to clean the windows, this is much safer. Window cleaners mustn’t take unnecessary risks or misuse equipment, which can increase the chances of injury.

That’s why it’s vital to have fall prevention. Accidents can occur. That would have been quite a stressful working day for this window cleaner.
  2. Average pay: Skyscraper window cleaners make between 19 and 27 dollars per hour in the US (2). The median pay is 23 dollars per hour.
  3. It can take months to clean a skyscraper: Cleaning a skyscraper is no small task. For instance, six people take about four months to clean the Empire State Building. When they finish, they have to start all over again!
  4. Skyscraper window cleaners see it all: You won’t necessarily know when the window cleaner is coming round if you live in a high-rise building. Window cleaners see it all. They have seen people sleeping, using the bathroom, and walking around in their birthday suits!
