Find information about different cleaning methods used for Ecophon systems and how you can avoid unnecessary soiling of the ceiling. This is of great importance since cleaning properties affect both life-span and economy.


It is important to choose the most suitable system (also considering the corrosion class) for the intended application. Consider the enviroment regarding type of soiling and what cleaning methods (incl. frequency) and agents (and its concentration) that are to be used. If there are doubts regarding the cleaning agent it is always wise to test the chemical on one tile before using it on the whole area.

How to avoid unnecessary soiling

  • Regular maintenance of the ventilation system
    Ventilation is often responsible for soiling ceilings. Regular maintenance of the ventilation system is one way of minimising this. Generally, a displacement ventilation system (a ventilation system with low velocity air supply located at low level) gives less soiling than a mixing ventilation system (with the air supply in the ceiling).
  • Avoid pressure differences
    Another way to keep the ceiling clean is to avoid pressure differences between the room and void. Open grilles, perforated shadow-line trims, open light fittings or similar can eliminate such pressure differences. If there is a pressure difference, the ceiling will act like a filter and might become dirty. It is important that the ceiling can be cleaned throughout its service life. This applies particularly to ceiling tiles that become soiled around ventilation components, or when installations in the ceiling void are serviced.
  • Wear clean cotton gloves
    To avoid unnecessary soiling it is alo advisable to always wear clean cotton gloves when handling the panels.
  • Install the ceiling as late as possible 
    For the same reason the ceiling should be installed as late as possible in the building process.
  • Clean particularly exposed areas regularly
    If the entire ceiling or parts of it are particularly subjected to soiling, it is important to get it regularly cleaned. In this way the cleaning work will be straight forward, rather than allowing dirt to build up over long periods of time. Using clips on the back of the ceiling tiles facilitates cleaning.

Evaluation of Ecophon systems

The Ecophon systems have been subjected to extensive tests and evaluations, both by third party institutes and internally. Example of equipment and standards used are the Gardner test equipment (as described in EN ISO 11998). The cleaning methods and frequencies are based on our knowledge on how the systems are maintained and cleaned in various applications and through cooperation with leading international suppliers of cleaning agents and equipment. This is taken under consideration during the development of new products to be able to deliver the most cost efficient systems.

Hydrogen peroxide vapour (HPV) test

Ecophon systmes are subjected to a HPV (hydrogen peroxide vapour) test. HPV is often used to disinfect rooms in hospitals. The HPV test is designed by Bioquell (producer of HPV equipment) to determine how different products and materials are affected by HPV.

The test is performed in a specified room (27 m3) where the product is exposed to Bioquell´s HPV decontamination system. A timed gassing cycle is run: the room is then returned to an ambient temperature of 20 to 25°C before each cycle. The test has totally 40 cycles and the panels are exposed to a dosage of 14 g/m3 HPV. All Ecophon Hygiene products withstand HPV.

Expected lifetime

The expected lifetime of a ceiling system is approximately 20 years and the performed tests on the systems have been designed for at least that period of time. The systems will therefore be insignificantly affected with respect to the declared properties (such as fire safety and acoustics) after 20 years of use. However, unique circumstances can affect the systems in an unpredictable way. 

Cleaning methods

Find below explanations to the cleaning methods mentioned in the Technical properties section on the product pages.


Dry cleaning

Dusting should be carried out with a dry, soft (microfibre) cloth, a soft brush or similar.

Vacuum cleaning should be conducted with reduced suction and a soft brush as for textiles, curtains etc.


Wet wiping

Wet wiping should be carried out with a soft sponge or (microfibre) cloth saturated with water or a detergent solution of the same type and concentration as is recommended for use on indoor painted surfaces. Use circular movements with moderate pressure during wiping of the surface.


Wet cleaning (Low pressure)

Wet cleaning is a three step process. Apply the cleaning foam or gel on the surface to let it dissolve the dirt. Rinse the surface with water, and wipe it dry with a clean, well wrung-out (microfibre) cloth or sponge so that the dirt released into the rinsing water does not dry and leave stains. Some cleaning agents are quite corrosive - choose a suitable corrosion class on the system depending on the cleaning agent.


High pressure washing

High pressure washing uses only water at varying temperatures and pressures.

The recommended working pressure is 2-4 MPa (20-40 bar). Working pressures up to 8 MPa can be used, provided that the scattering angle is at least 30° and the distance between the nozzle and the surface is at least 300 mm. Most effective rinsing is achieved by holding the nozzle at an angle of about 45° to the surface.



Disinfection is a method to kill microorganisms with common types of chemicals such as ethanol, isopropanol and sodiumhypochlorite. Apply the disinfecting chemical by spray or by using a wetted (microfibre) cloth.


Steam cleaning

Steam cleaning uses only steam to dissolve stains and kill microorganisms. The steam can be produced at different pressures which creates higher or lower water content of the steam. The steam should be applied through a nozzle together with a microfibre cloth or a soft rubber scraper. Use circular movements with moderate pressure during cleaning.
