A few weeks ago, Prius was taken over! The windshield becomes a milk glass every few weeks. With spirit and glass cleaner it smears, as well as with nitro thinning silicone and wax remover? Only possibility to rub off with a kitchen crepe under high effort, and constantly replace until whole roll is consumed. Drive now 40years, such a lubricated I had never before, and was cleaned only every few years. What dissolves this lube, which looks as if the disc is always fogged inside and strongly hygroscopic. Antifreeze negative, moisture negative, refrigerant negative, gassing electrolyte from the NIMH battery?
