Ash season is hard on glass in the Sonoma Valley — here is how to protect yours.
Kenwood sits in the narrow stretch of the Sonoma Valley between Sugarloaf Ridge and the Mayacamas, and by late summer the whole corridor along Highway 12 knows the drill. Smoke settles in the valley overnight, and by morning there is a fine gray film on every vehicle parked from Warm Springs Road down to Oakmont. Most people reach for the wipers. That single reflex does more windshield damage around here than any rock on the highway.
Wildfire ash is not soot. It carries fine silica and mineral particles — essentially powdered rock and burned mineral content — and it is harder than the laminated glass in your windshield. Run a dry wiper blade across it and you are dragging grit over glass under spring pressure. The result is the hazy arc of fine scratches you notice the first time you drive Highway 12 east into the morning sun, or west toward Santa Rosa at dusk. Those scratches do not buff out, and a badly scoured windshield eventually has to be replaced for visibility alone.
Evacuation routes out of Kenwood are narrow and often gravel-shouldered, and everyone is moving at once. A chip you have been putting off is exactly the thing that spreads across your line of sight on that drive. Handling it early is cheap insurance.
