[00:00:00] As we know, some car owners are not concerned with shiny paint or glossy rims. However, it's our obligation to ourselves and our fellow drivers to ensure the best possible vision while on the road. So today, we're going to tackle removing road contamination on your windshield. And on part two of this series, we'll be focused on cleaning the stubborn and hazy yellow film on interior glass for a glare-free ride home. That's coming up on AutoBlog Details. My name is Larry Kosilla,

Here are the items you'll need for this task. Windshields are subject to a vast array of punishment that range from acidic bugs, sand, rain, road oil, stones, and even old wiper blades. So taking a few minutes each month

[00:01:00] to inspect the windshield is vital to your safety. First, lift the windshield wipers off the glass, as we'll work on them last. Next, apply a liberal amount of glass cleaner as lubrication for the razor blade. The razor blade extension is extremely helpful for gaining leverage and the proper glass-to-blade angle required for this technique. Glass is extremely hard, which allows us to use the razor blade for the most efficient clean possible. With the glass cleaner as lubrication, hold the extension at a 45 degree angle

[00:01:30] and move top to bottom in tight, overlapping, parallel lines. This will quickly remove any embedded bugs, road tar, or sap from the windshield which causes the wiper blade to bounce over these contaminants, thus reducing the blade's contact with the glass and its ability to wipe water away, leaving streaks in your line of sight. Repeat on the other half of the windshield. Then, add another quick mist of glass cleaner. Wipe dry with a shorthair microfiber towel. And immediately buff with a regular microfiber towel

[00:02:00] to remove any remaining moisture which may become water spots as it dries. With the wiper blade still off the glass, spray two squirts of glass cleaner into an old microfiber towel or paper towel. Pinch the cloth between your thumb and pointer finger, and gently squeeze the cloth as you slide it down the rubber wiper blade. This will remove any baked-on road debris and extend the life and efficiency of the rubber. Afterwards, you'll see black gunk on the towel from the blade, which is totally normal.

[00:02:30] However, if the rubber is dried-out or broken in any way, replace them altogether. For an added layer of protection from the elements, add a hydrophobic repellant for increased rain and bad weather clarity. With just a few basic and inexpensive tools, you can clean your windshield efficiently and more effectively than traditional rags, newspapers, or paper towels.
