The first is the simplest one you just need to pour few drops of synthetic vinegar on the glass and with the help of a cotton cloth rub the glass until the hairspray dissolves. Then take a dry cloth and clean the glass. Try any brand of synthetic vinegar or whatever might be convenient for you.

Pour a moderate quantity of the mixture and rub the glass with the help of a cloth. In the end take a dry cotton cloth and wipe it completely.
