There is nothing
worse than driving in the rain with bad windshield wipers,
when your windshield gets blurry from the water your blades
aren't whisking away. Here is how to clean them yourself,
rather than simply buying a new pair.
Using an old cloth,
dampen the cloth with white vingear, then run the cloth down
each windshield wiper blade twice. Then use a second cloth
with water, and rub down each blade to remove any residual
vinegar. Your wipers will work much better next time you are
driving in the rain.
