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.
