Forget Expensive Car-Care Chemicals: How to Get Your Windshield Crystal Clear

A car's windshield can become coated with dust and grime surprisingly quickly, regardless of the season. Washer fluid may provide a temporary solution, but it isn't enough to deliver a truly spotless finish.

Auto30 took a closer look at how drivers can get their windshields crystal clear using a simple household product.

What to Use to Clean a Car Windshield

Ordinary vinegar, a staple found in most kitchens, can help clean a windshield until the glass is clear and streak-free.

The key ingredient is acetic acid, which is known for its disinfecting and degreasing properties. It can help break down dried-on bugs, bird droppings, tree sap, and streaks left by hard water containing high levels of minerals.

How to Make a Vinegar Cleaning Solution

Don't apply concentrated vinegar directly to the glass. Instead, dilute it with an equal amount of water. Use a microfiber cloth to wipe the windshield to help prevent scratches.

It's also worth remembering that frequent use of undiluted vinegar can damage rubber seals, plastic components, and the vehicle's paint.

How to Use Vinegar in Winter

Some drivers also use vinegar during the winter to reduce interior windshield fogging and help prevent ice from forming on the glass.

There is a real chemical principle behind this method: a substance dissolved in water lowers the mixture's freezing point, much like salt does on roads during the winter.
