Why, back in the '52 Morris Minor sidevalve days...

















A little squeeze bottle with diluted sudsy ammonia, applied via left arm, thumb+forefinger, occasionally -- kept that windshield streak free and clear. (No $150 German w/s washer motors needed - oh, and apparently: real 'rubber' lasted longer then, as regards these 'improved' hi-tech "elastomer wiper appliance-attachment$")
