Ecophon ceilings can be dusted, vacuum cleaned, wet cleaned or foam cleaned with high pressure hosing, depending on actual sound absorber and construction of the ceiling system.
In order to obtain a long-lasting ceiling with a long service life and economical maintenance, the visible surface should be dirt and dust repellent and easy to keep clean. Ecophon panels with Akutex T are a good choice, as they have a coating that prevents dust from adhering. Therefore, they have a high resistance to soiling.

How to prevent soiling
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).
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.
To avoid unnecessary soiling it is advisable to always wear clean cotton gloves when handling the panels.
For the same reason the ceiling should be installed as late as possible in the building process.
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.
Dusting should be carried out with a dry, soft cloth, a soft brush or similar.
Vacuum cleaning must be conducted with reduced suction as for textiles, curtains etc.
Manual wet cleaning
Wet cleaning should be carried out with a soft sponge or cloth saturated with a detergent solution of the same type and concentration as is recommended for use on painted surfaces. After washing, rinse immediately with clean water. Use circular movements with moderate pressure during both the washing and rinsing of the ceiling surface. Wipe dry with a clean, well wrung-out cloth or sponge so that the dirt released into the rinsing water does not dry and leave marks.
High pressure washing
In rooms with a requirement for regular washing or washing methods such as foam cleaning with high pressure hosing, we recommend Ecophon Hygiene panels with Connect C3 grid system. The Hygiene systems can withstand more frequent and/or extensive cleaning and the Connect C3 grid system fulfils corrosivity category C3 according to ISO 12944-2.
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 of the ceiling is at least 300 mm. Most effective rinsing is achieved by holding the nozzle at an angle of about 45° to the ceiling.
Resistance to wet abrasion
There are several methods for testing the resistance of painted surfaces to wet abrasion. Ecophon has used the Gardner machine (as described in ASTM D 2486 and SS 184164) to determine the wet abrasion resistance of the panel's surface. The Gardner machine features a standardised abrasive brush that is passed over the panel's surface. The number of cycles needed to penetrate the surface is counted and can be used as way of judging the relative strength of various painted surfaces.
