Professional cleaning has moved from experience-based manual labor to a documented trade with common standards, regulated chemistry and strict environmental requirements. We follow the traces that can be documented: the common Nordic quality standard DS/INSTA 800 from 2000, CLP labeling of cleaning chemicals, the AMU education path and today's stricter environmental requirements.
Introduction
Cleaning as work is ancient, but professional commercial cleaning as a profession has developed closely together with its regulatory basis. Today a cleaning technician works according to a common quality standard, doses chemicals according to label and safety data sheet and prevents infection with system. This article sticks to the part of the story that can be documented in standards, legislation and the profession's own teaching materials.
From manual work to system
For a long time, cleaning was an experience-based trade, where quality was measured by how often cleaning was done — the frequency — and by individual skill. What really made cleaning into a trade is not one new tool, but the requirement to be able to put numbers on the result: what does 'clean' mean in a particular type of space, and how do you verify it objectively?
DS/INSTA 800 — quality becomes measurable (from 2000)
The decisive shift came with the common Nordic standard DS/INSTA 800 which was first released on 1 September 2000. It reversed the logic: instead of agreeing on a frequency you measure the result — how clean it actually is after cleaning. A room is divided into object groups (furniture walls floor ceiling) assessed for certain types of dirt and held up against an agreed quality level. The standard was later revised; the version the trade uses today is the 4th edition from 2018 with errata sheet from 2019.
- 01Result measurement rather than frequency — you assess how clean something is, not how often it is cleaned.
- 02Object groups and contamination types—a common language for what is inspected.
- 03Inspection unit up to 100 m² – the basis for spot checks.
- 04An agreed quality level (1–5) — so requirements and control can be understood by both customer and provider.
Chemistry is regulated (CLP from 2008/2017)
At the same time, cleaning chemistry was systematized. Classification, labelling and packaging of chemicals in the EU is governed by the CLP Regulation (EC No. 1272/2008), which is based on the UN's globally harmonized system (GHS). Since 2017, only red/white hazard pictograms have been valid. For the cleaning industry, this means that products bear signal words and H and P statements, and that a safety data sheet (SDS) with 16 fixed sections is available for dangerous products. This made precise dosing, hazard symbols and personal protective equipment into documented requirements rather than loose practice.
- 01CLP/GHS — common European hazard symbols (GHS01–GHS09) and signal words.
- 02Safety data sheet (SDS) — 16 mandatory points including personal protective equipment under point 8.
- 03Chemical risk assessment — the workplace must assess the risk of the means used.
