Otto Christ AG updates technical specifications for car wash brush materials
German manufacturer Otto Christ AG has released updated technical guidelines regarding the selection and maintenance of materials for rollover car wash systems.
Otto Christ AG, a manufacturer specializing in vehicle wash technology, has published revised operational recommendations for its rollover car wash systems. The guidelines focus on the selection of washing materials—specifically brush filaments—to balance cleaning performance with paint surface protection.
As vehicle manufacturers utilize increasingly sensitive clear-coat finishes, the requirements for physical wash components have become more stringent. The technical update emphasizes how material density and fiber geometry impact wear and the mechanical friction applied to vehicle surfaces during the wash cycle.
The report clarifies the maintenance requirements for brushes to prevent surface contaminants from affecting wash results. By standardizing these material parameters, the company aims to reduce the mechanical stress on vehicle exteriors while maintaining the operational lifespan of the wash brushes. These specifications apply to the current range of rollover units installed across the firm's global service network.
