Cleaning the wind screen with a clean scraper! Auto service 470 is built to keep a water can on the upper shelf. The customer simply fills water with a button press. The lower part is designed with a water container to effectively clean the scraper, and the ability to rub the scraper against a “washboard”. By pushing a button, the customer rinse the scraper with clean water. The unit is built in stainless steel with a thermostat controlled heater.
