The history of cleaning – from scrubwoman to professional service professionalism

Cleaning has existed as long as humans have lived together, but for most of history it was not a profession – it was domestic work that mostly fell on women and servants. Getting clean was something you just did, not something you were trained for, had standards for or were measured on. The path to the modern service assistant is the story of how this work became a profession with knowledge of chemistry, hygiene, machines and quality.

Before industrialization cleaning tools were few and simple: brooms and sweepers made of twigs or bristles, a scrub brush, cloths from old clothes, a bucket, and lots of muscle power. Wooden floors were scrubbed on the knees with sand, lye, and soft soap, and water often had to be carried in and heated over fire. Soap was an expensive household product that people previously made themselves from fat and ash (lye), and it was neither standardized nor mild on hands. Cleaning was physically hard work that took a long time, and the result depended entirely on the individual's diligence and strength.

§The industrialisation — cheap soap and the first machines

With industrialisation in the 1800s cleaning changed markedly. Soap could now be made at factories in large scale and became cheap enough that ordinary homes and businesses could use it abundantly. Over the century an entire industry of cleaning products grew: scouring powders soap flakes and later the first true cleaning and disinfection products. Towards the end of the 1800s and beginning of the 1900s also came the first mechanical aids — carpet sweepers and forerunners of the vacuum cleaner — that began to ease the worst drudgery.

§Bacteriology Makes Cleaning Health

The most important change in the 1800s was not a tool but an insight. Until the middle of the century people did not know that invisible microorganisms spread disease. In 1847 the Hungarian physician Ignaz Semmelweis showed at a hospital in Vienna that mortality from childbed fever dropped dramatically when doctors washed their hands — from around 18 per cent down to a few per cent. During the Crimean War in the 1850s Florence Nightingale reduced mortality at a military hospital through cleanliness ventilation and clean linens. And in the 1860s and 1870s Louis Pasteur Robert Koch and Joseph Lister finally explained why with germ theory. Suddenly cleaning was not just nice — it was health.

“Semmelweis could see that hand washing saved lives long before anyone could explain why. The explanation — microorganisms — came only a generation later.”

§From domestic wear to profession

As cities, factories, hospitals and offices grew, cleaning became something you bought as a service. Throughout the 1800s and 1900s, cleaning developed from domestic work to a profession with employees whose sole task was to keep things clean — in hospitals, institutions and large companies. Over time, work clothes, fixed procedures and eventually actual education came too. The trade changed its name several times and became broader: from 'cleaning assistant' towards the modern service assistant, who in addition to cleaning also handles practical service, hygiene, waste management and quality assurance.

§The modern era — microfibre, chemistry understanding and machinery

The post-war period and recent decades have brought a series of technical leaps. Floor washing and polishing machines took over the heavy floor work, microfiber cloths and mops made it possible to clean efficiently with very little water and chemicals, and products were assembled according to dirt type with knowledge of pH and detergents. At the same time came eco-labels such as the Nordic Swan and EU Flower, which make it possible to choose products with less environmental and indoor climate impact. The profession went from raw physical work to knowledge: today you must understand what a product does and why a method works.

§When 'clean' became something you could measure

One of the most recent and largest shifts is that cleaning quality has become objective. The Nordic standard DS/INSTA 800 makes it possible to agree measure and document a quality level so customer and provider speak the same language. Where 'clean' previously was an opinion that varied from person to person it is today something you can check against an agreed level. It is perhaps the clearest sign that cleaning has become a profession: when the result can be measured professionalism can also be assessed.

Looking back, the history of cleaning is a journey from muscle power to knowledge. The scrubbing woman and the modern service assistant share the goal — to clean and maintain hygiene — but where it once meant working hardest, today it is about choosing right: correct method, correct dosage, minimal strain and measurable quality.

“The craft went from being about who scraped hardest to being about who chooses right.”
