Is it advisable to activate the windshield wipers when the glass is completely dry?

Question

DentroTest · Accepted Answer

No, you should never activate the windshield wipers when dry. Dust and dirt accumulated on the glass act as an abrasive material (like sandpaper) that, when dragged by the blades without water lubrication, can irreversibly scratch the windshield surface. These micro-scratches scatter light from other vehicles' headlights, increasing the risk of glare and reducing visibility. Furthermore, excessive friction deteriorates and tears the wiper blade rubber quickly. If you need to clean the glass, you must first activate the windshield washer (fluid jet) to moisten the area.
