After a while and depending on the surrounding environment, a layer of insects and dirt may appear on the wind turbine blade in operation – in particular on the blade leading edge. Such a layer badly influences the blade effectiveness. Thus, a regular blade cleaning is recommended. Various (biodegradable) cleaning agents can be applied for gel coat surface cleaning and maintenance.
Three brush system with biodegradable soap supply allows for efficient removal. On average 10 hours required to clean all 3 blades of one turbine, unless the blades are extremely dirty and need additional cleaning.
