Cleaning and Maintance of perforated and slotted surfaces

Cleaning and Maintenance

General information:

Acoustically effective products should generally be treated differently from products with a closed surface.

Veneered/lacquered surfaces:

Cleaning of a veneered/lacquered surface should be done at the earliest after the lacquer has dried through, depending on the temperature not earlier than 7 days.


Please do not use abrasive cleaners or cleaners with bleaching additives under any circumstances.


Moisture penetration into the perforation must be avoided as swelling of the panels may occur. Moist cleaning of the panels is not permitted, especially splashing of water must be avoided at all.


If panels are more heavily soiled, a very slightly damp cloth should be used. Use this to wipe the surface of the panels in the direction of the grain and then dry with a soft cloth.

Other cleanings:

Never use glimmer-forming or silicone-containing cleaning and care products (“furniture polish”), as this treatment makes subsequent refreshing and repair work on the lacquer surface more difficult or impossible.

Dust removal:

For the care of perforated or slotted surfaces, we recommend using a dry dust cloth and dusting the surface in the direction of the grain.
The use of microfibre cloths, which can attack the finish lacquer, is not recommended – especially for lacquered surfaces.

Outdoor use:

Perforated/slotted surfaces are not intended for outdoor installation.
