Methods are disclosed to facilitate the removal by complete release or shattering of a frozen mass of ice or snow which has become merely trapped beneath a wiper blade during its movement. In particular there are described methods and accompanying structures for removing such frozen masses by vibrating a wiper blade at high intensity of vibration. In other methods, frozen masses are released by the use of pressurised air acting against a window across which the wiper blade operates.
