Use a soft cloth and a vinegar-based household cleaner to clean our keyboards. Exert slight pressure with the cloth, which has been soaked with the cleaner and then squeezed out, and remove any dirt with circular movements. Then wipe the cleaned surface with a damp cloth in order to remove any remaining cleaning agent. When disinfecting, we recommend that you use an alcohol-based disinfectant in line with the manufacturer’s specifications.

Never use any abrasive substances, such as steel wool or aggressive scouring agents, to remove stubborn marks. Do not use any cleaning agents containing substances that are listed as non-resistant in the following table.
Chemical resistance according to DIN 42115
In a departure from DIN 42115, the reaction time was extended to a period of 24 h. The assessment took place directly after chemical residue was removed and was then repeated after 24 h.
