A method of cleaning a radar sensor for a vehicle comprises monitoring a signal output from an external radar sensor for the vehicle with an electronic control unit and comparing the signal output to a signal quality threshold. Debris is cleaned from a protective screen located between the sensor and the external environment of the vehicle when the signal output is below the quality threshold. Cleaning the debris from the protective screen is performed by one of heating the protective screen by activating a heating element located proximate to the protective screen or spraying a fluid from a nozzle located in a bezel surrounding the protective screen and proximate to the protective screen over the exterior surface of the screen.
