The reference work for the cleaning trade: DS/INSTA 800, pH and surfaces, dosing, microfibre, colour coding, disinfection and working environment — plus templates and checklists for everyday use.
A trade with responsibility, system and a direct path from apprentice to specialist
Professional commercial cleaning is much more than dusting: quality is measured against a standard (DS/INSTA 800), chemicals are dosed precisely, and cross-contamination is prevented systematically. Here's why the trade is worth considering — and how to get started via AMU.
Quality is measured by the result, not by the frequency
DS/INSTA 800 is the key standard for cleaning quality in the Nordic countries. It measures how clean a place is AFTER cleaning — not how often cleaning is carried out. Here are the principles: quality levels, object groups, soiling types and inspection units.
Acidic, neutral and alkaline — and what they are used for
pH determines what a cleaning agent can do: acidic agents dissolve limescale, alkaline ones dissolve grease, neutral ones are for everyday cleaning. Here is the breakdown — and the important safety rule of never mixing acidic and alkaline.
How to read the label and safety data sheet on cleaning chemicals
Cleaning chemicals are regulated by the CLP Regulation. The safety data sheet has 16 fixed sections, and the label carries a signal word, H- and P-statements, plus one or more of the 9 hazard pictograms. Here is what they mean.
When to use what — and why microfibre works
Microfibre cleans through mechanical scraping, static electricity and capillary absorption — often with plain water and no chemicals. The three moisture states (dry, damp, wet) determine what the cloth can do, and washing/maintenance determine how long it lasts.
Avoid cross-contamination with red, yellow, blue and green
Colour-coded equipment prevents bacteria from being moved from, say, the toilet to the kitchen. A widespread Danish model is red/yellow/blue/green — but sources vary, so let the workplace define its own chart.
Alcohol, chlorine and quaternary compounds — concentration and contact time
Disinfection requires the right concentration AND contact time. Alcohol 70–85 %, chlorine 0.1 % (1000 ppm), quaternary ammonium compounds 0.5–5 %. The efficacy must be documented to EN standards.
Gloves for wet work, ergonomics and workplace risk assessment
Cleaning is physical and involves chemicals and wet work. The Working Environment Authority recommends gloves for wet work, a chemical risk assessment must be in place, and good ergonomics prevent musculoskeletal disorders.
Zones, frequency, output and crew size
A cleaning plan starts with a survey: area in m², zones and frequencies. With a productivity figure (m²/hour) you can calculate the time and team size — but remember that a productivity figure is always an estimate.
Linoleum, vinyl, ceramic tiles, natural stone and wood — and acid sensitivity
The choice of cleaning agent depends on the floor type. Most importantly: natural stone, limestone and marble are acid-sensitive and must not come into contact with acidic agents. Here is an overview and the principle behind it.
Room × task × frequency × responsible person
A cleaning plan describes which tasks are carried out where, how often and by whom. Here is a column template you can copy and fill in — with no binding figures, so it fits your premises.
Office · toilet · kitchen · corridor · meeting room
A short checklist per room type so no object groups are forgotten. The lists are bullet points you can copy — frequency and method are adapted to your plan.
Visual inspection per object group + joints
A form for visual inspection per DS/INSTA 800: record types of soiling per object group and count occurrences. The actual accept/reject limits are read off in your own licence.
Product · pH · pictogram · dosage · protective equipment
A register of the workplace's cleaning chemicals — so that dosage, pH, hazard symbols and protective equipment are gathered in one place. The fields are filled in from each product's label and safety data sheet.
Sammenhæng mellem kemi, mekanik, temperatur og tid
Sinners cirkel beskriver de fire faktorer der tilsammen bestemmer rengøringsresultatet: kemi, mekanik, temperatur og tid. Øger du én faktor, kan du sænke en anden — og det giver et praktisk redskab til at vælge den rigtige metode.
300 µl/m², 90 % miljømærkede produkter og strammere transport
Kriterie-version 4 for Svanemærket rengøringsservice trådte i kraft 18. november 2024. Kemiforbrug skæres til maks. 300 µl/m², andelen af miljømærkede midler hæves til 90 %, og alle nye køretøjer skal være el/hybrid eller bio-/naturgas. Her er hvad det betyder i praksis.
Arbejdspladsbrugsanvisningen er afskaffet — risikovurderingen består
Fra 1. januar 2026 er den danske arbejdspladsbrugsanvisning (APV-kemibilaget) afskaffet som separat dokument. Det ændrer ikke ved kravet om en kemisk risikovurdering og instruktion af de ansatte. Her er hvad der faktisk er ændret — og hvad der ikke er.
Hvordan professionel rengøring blev målbar, reguleret og uddannet
Professionel rengøring har bevæget sig fra erfaringsbaseret håndarbejde til et dokumenteret fag med fælles standard, reguleret kemi og skarpe miljøkrav. Vi følger de spor, der lader sig dokumentere: den fællesnordiske kvalitetsstandard DS/INSTA 800 fra 2000, CLP-mærkningen af rengøringskemi, AMU-uddannelsesvejen og nutidens skærpede miljøkrav.
