Indoor Air

Maintenance cleaning that is kind to indoor air

Maintenance cleaning has to be done on a regular, perhaps daily or weekly, basis. The idea is to maintain an agreed level of cleanliness and ensure that facilities function well between cleans. Cleaning frequency is based on a facility’s purpose and preferred level of cleanliness.


Good maintenance cleaning affects indoor air. Cleaning textiles should be prepared in a specially designated cleaning room. Employees should take only pre-prepared mops and cloths along. A pre-prepared solution is created from measured dilutions of a concentrated cleaning agent. The cleaning textiles are moistened with the solution. For the easy preparation of cleaning textiles, concentrate can also be added to the fabric conditioner compartment of a mop washing machine. Ready-to-use spray products and bottles are not recommended for pre-preparation or professional cleaning.

An aseptic approach, which binds dirt rather than spreading it from cleaned to uncleaned areas, is a key element of maintenance cleaning. Regular dusting of upper surfaces and cleaning of ventilation outlets are also important to maintaining clean indoor air. Keep surfaces clear of clutter to promote dust-free tops.


Correctly dispensed cleaning agents do not accumulate on surfaces if modern cleaning methods are used. They do not even wet surfaces when used sparingly. Automatic floor scrubbers and microfibre mops prevent the accumulation of cleaning agent, by removing any excess solution from surfaces.

Cleaner indoor air can be achieved with the right cleaning agent and cleaning machines. Being more efficient than manual cleaning, cleaning machines should be used for maintenance cleaning whenever possible. Floors should be cleaned with automatic floor scrubbers. The cleaning agent and any grime it removes will be picked up by the machine.


In general, a very small amount of cleaning agent should be used for maintenance cleaning. The typical dilution is 1–5 ml/1 l water, or 0.1–0.5%. Because getting the amount right is important, we recommend a dispenser or pump for dispensing a cleaning agent. Indoor air is most affected by a cleaning agent’s odour and solvents. A fragrance-free and solvent-free cleaning agent should be used for maintenance cleaning. Another indicator of product safety is the Nordic Ecolabel, which indicates compliance with a number of user safety standards.


  • a fragrance-free cleaning agent
  • a solvent-free cleaning agent
  • a product with the Nordic Ecolabel
  • an allergy-approved product
  • a dispenser or dispensing equipment
  • cleaning equipment and machines that are in good condition
  • floor care methods that reduce basic cleaning

Insufficient maintenance cleaning makes facilities less attractive and lowers the value of real estate. Good maintenance cleaning guarantees the safety and cleanliness of facilities, and improves indoor air quality.
