Answer 1

Glass cleaning fluid. Only blue, not green. Mister propper, take the blue one without a sprayer - it is not expensive and proven.
You don't need vodka - there is sugar and glucose - it's not good for the head.

Answer 2

There are special liquids googled, for example, here color-print39.ru/servisnye_zhidkosti/promyivka-dly...
