Vegetable used as early windscreen wiper

[Dad17]

what vegetable was used a windscreen wiper in the early days of motoring?

[stanleyman]

It might have been half of a potato.

I think it was 2 sticks of celery. Early police cars used to stick half a potato on the roof as a substitute for a flashing light. A PC had to walk in front of the car waving a flag and shouting NER-NER NER-NER..probably.

If they had a smash I suppose it would be mashed potato.

early cars often had leeks

...and some suffered from car-rot

[mata hari]

Yes I agree it was the old spud!

they say that if your wipers are past there best that you should cut a potato in half and rub it on the blades to make them work better!!
