We live in the Pacific Northwest which is known for it’s rainy weather. Even with this reputation our windshield wiper blades go for long periods of time without being used. After setting against the window and bent to one side for a long time the blade will want to stay bent to one side and not flip back and forth like they were originally design to.
Using a tennis ball between the arm and the coach will take this pressure off the blade and thus they will not take a set in one direction.
Couple of lessons learned:
1) Put remove the tennis balls on your moving checklist.
2) When you put the ball between the coach and the wiper arm be sure not to pinch the windshield washer tubing.
