If you use your windshield wipers when your windshield is mostly dry, are you damaging them at all?
My understanding has been that using your wipers on a dry windshield increases the amount of friction the motor has to work against, and therefore wears it out quicker as well as causing potential damage to the rubber blades. Is this true? If so, how much do you have to overwork the motor before it goes kaput?
This has always been a pet peeve of mine. They make cars smart but they can't make the washer squirt before the wipers turn on.The primary concern with wiping dry windows is abrasion. as you drive or simply being parked dirt and grit accumulates on the glass. Some of it possibly glued in place by tree sap. As the dry wiper moves across the glass it is dragging the grit with it. This causes the wiper rubber to wear and scratch the glass.
