Cleaning and Material Resistances

Use a soft cloth and normal cleaning agents suitable for stainless steel surfaces when cleaning our keyboards. Place a small amount of the cleaner on the dampened cloth and remove any dirt with circular movements and only slight pressure. 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.

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.

Use a cleaning brush to clean our plastic keyboards in a dry state. You can also wet the keyboards to clean them if they have at least an IP65 degree of protection - e.g. to remove any sticky dirt. Use a cleaning brush and, if necessary, a normal cleaning agent under warm running water (max. +60°C) to clean our plastic keyboards.

The IP protection (ingress protection) classes apply in line with DIN EN 60529:2014-09 and provide information about the degree to which solid foreign objects and dust (indicated by the first IP figure) or moisture and water (indicated by the second IP figure) penetrate that item.

The protection classes are not valid with regard to electrical safety and protection from outside influences.

All the degrees of protection for the following categories are tested at our own company laboratory:

• IPX7 – Protection against temporary immersion
• IPX8 – Protection against continuous immersion

The test takes place in a tank. An idle period of 72 hours ensures that the temperature of the water adapts to the room temperature. An optical check on the surface and function then takes place and checks are made to determine whether any water has penetrated the item.

You will find our products categorised according to the IP classes [here].
