Keeping glass clean and free of debris is one of the most basic premises of auto glass maintenance. A clean windshield is easier to see through while driving. It is also far safer than a windshield with an accumulation of debris. Debris can scratch a windshield which can leave to lasting damaged and fast deterioration. Trying to clean a windshield with abrasive debris using wipers is a bad idea, as it just makes the regular fluid abrasive. When washing a windshield by hand, use a gentle touch and a non abrasive cleaner to ensure lasting windshield functionality.
Standard windshields and tinted windshields alike can benefit from regular cleaning. Obviously, a driver doesn’t want to operate a vehicle with a dirty windshield as it can obstruct views and cause distractions. This puts the driver at greater risk for accident and injury. It can also risk damaging the windshield if left to pile up to dangerous levels. Cleaning a windshield should only be done with gentle, non abrasive cleaners and cleaning supplies. This will protect the life of the windshield during and immediate wash and during the overall life of the windshield.
When a driver uses windshield wipers with a gritty windshield, they risk damaging the windshield and causing scratches or other abrasions. Dirt, dust and debris particles can all be scraped across the windshield by a windshield wiper can easily damage the glass, even when windshield wiper fluid is used. The same is true of washing the car overall. Using a soft cloth, warm water and a very delicate cleaner with no abrasive particles is almost always the best way to clean a windshield. This method will protect extra features like window tinting, window mounts for antennas and defrost/defog strips or real or front windows.
There’s nothing wrong with trusting your windshield wipers for a little bit of dust or the occasional bug, but using them when the windshield is seriously dirty can be a bad idea. When a windshield has been covered with dirt, natural debris or other gritty materials, taking a careful and delicate approach is usually best. Using a non abrasive cleaner to remove the dirt carefully is the safest, and usually the cheapest, way for a driver to ensure the window is safely and carefully cleaned. A simple dish soap or auto soap with no harsh or abrasive chemicals or additives is usually fine for this use.
