Keeping your vehicle's windshield clean is extremely important to make it safer for you and other drivers on the road. A dirty windshield can obstruct your view while driving and also make your car look dingy. Fortunately, it's possible to make your windshield clean, streak-free and sparkly new. Here's a step-by-step guide on how to go about it. Plan Your Cleaning Cleaning the windshield should be the last thing you do if conducting a thorough clean-up of your vehicle. Otherwise, there will be chances of spilling or dropping of liquids on its spotless surface when cleaning other areas. Also, park your car in the garage or shade before beginning to clean. If the vehicle is parked out in the sun, the glass cleaner might evaporate even before you begin to scrub it off. Get all the Equipment Ready First, choose a good quality ammonia-free glass cleaner. Plain water is also a great cleaner but it is not as effective. Use your cleaner with a high-quality microfiber towel. If you have difficulty reaching the different areas of your windshield, use a step-stool to gain some height. Start with Cleaning the Exterior Lift the wipers up so that the area beneath them gets cleaned as well. Leave them in that position for the entire duration of the cleaning process. Now spray one half of the windshield with two or three squirts of glass cleaner. If your windshield is very large, you may need to use four or five squirts. Begin Wiping Vertically With your microfiber rag in hand, extend your arm to the upper centre of the windshield and bring it straight down along the central vertical line of your windshield. Return your hand to the top of the windshield but now slightly towards the side you\u2019re standing on. Wipe another vertical line down parallel to the first and continue wiping one half of the windshield in this way, progressively moving closer to the side of you\u2019re located on. You may use the step-stool to reach all the areas. Switch to Horizontal Wipes Once you\u2019ve completed a vertical wipe-down, switch to horizontal direction. Start again at the upper centre of the windshield and drag the towel straight out toward your side. Then, wipe another row just below the first one and toward the same side. Continue in this manner until the half of the windshield you started with is cleaned completely. Repeat the Pattern on the Other Half Now repeat the same process to clean the other half of the windshield. If, in this entire process, you need to go over a certain spot more than once, wipe over it with a straight back-and-forth motion. In case you discover chips or cracks, get the required auto glass repairs from trusted service providers like Windshield Experts before they worsen. Finish with Buffing Now you have to buff the windshield with a fresh piece of hand towel by moving your hand in a circular motion. Start on one side of the vehicle and move to the other side till the entire surface is covered. Depending on the size of your windshield, you might need several clean microfiber towels to wipe off the cleaner completely. Clean the Inner Side Cover the dashboard with used microfiber towels so that any glass cleaner doesn't get dripped on it. Now spray some glass cleaner on a soft scrub pad and begin scrubbing. Start from the upper-right corner of the passenger\u2019s side and move down the windshield in parallel rows, working your way to the driver\u2019s side. Remain in the passenger seat or lean into the car from the side door to avoid bumping or hitting the steering wheel while cleaning. Wipe Dry After that, use a dry microfiber towel to wipe through the entire surface and ensure there's no liquid left behind. Move your hand around the entire surface of the windshield in a small, tight circle. Cleaning the windshield in this way will also protect it from potential damages and spare you from the windshield repair cost.
