Defective windshield wiper: rub slice with apple

If the windshield wiper on your car gets into the rushes when it rains, and you still have to drive without being able to repair it, do the following:
Buy an apple, cut it in half, then drive with the cut surface of the apple from top to bottom over the windshield. The apple leaves an almost invisible film on it. This makes the water bead off. The water does not stop and then runs off directly and you can see again despite heavy rain.

I used this trick over 30 years ago on a truck and drove in heavy rain from Holland to Switzerland without windshield wipers. Works flawlessly.
